Our Guide To Cleaning & Maintaining Your Vortex Binoculars

Vortex is well-known for creating their outdoor adventure gear on the market since the 1980s, and when it comes to binoculars, they are one of the leading high-end brands in the market. 

Since Vortex binos do not come cheap, you must keep them in good condition, which means the binocular lenses have to stay clean as well as the binocular body from loose dust and loose dirt.

In our small guide we will cover why it is important to clean your Vortex binoculars and how often you should be doing, a step by step guide of how to clean them properly and some tips for maintaining them too.

Why You Should Clean Your Binoculars & How Often

Binoculars throughout their time when you use them will become exposed to all kinds of elements such as dust and pollen, and to prevent damage to the lens, you have to clean them regularly as part of binocular maintenance. 

Although it is important to regularly clean your binoculars when they start to look dirty, you should never clean them in excess as this can end up damaging the lens coatings.

Our Step By Step Guide To Cleaning Vortex Binoculars

Cleaning your Vortex binoculars is simple but you do have to make sure you are cleaning them properly to prevent any damage to their lens. 

We will list our step by steps to cleaning your Vortex binos below. 

Cleaning The Lens 

To clean the lens of your binoculars you need to make sure you have a micro fibrous cloth, pen brush, lens cleaners solution and some compressed air to get rid of dust particles. 

Never use paper towels or any facial tissue to clean binocular lenses as they can leave fibres and damage the lens. 

  • Step one - Before using your damp lens cloth you need to make sure you get any ingredient of dust out of the lens to prevent scratches. Hold your binos upside down and use your pen brush around the lens to loosen any debris then finish with the can of compressed air. 
  • Step two - Use a cotton swab with some of your lens cleaning solutions and move it over the lens coatings, never pour your solution straight onto the Vortex lenses.
  • Step three - Now use your microfiber lens cloth to wipe away the solution in circular motions and take off any more smudges.

Cleaning The Body 

Cleaning the outside of your binoculars is simple, all you need is a damp soft cloth to wipe down the exterior and use any cotton buds to get into the crevasse and remove dirt. 

Tips For Maintaining Your Vortex Binoculars 

To keep your Vortex high-quality binoculars in the best condition not only do you need to be cleaning them for a brilliant image but you should be maintaining them too. 

We've listed the best tips for maintaining your Vortex binoculars below.

  • Never touch the lenses - Avoid touching the lenses of your Vortex binos with your hands, fingerprints can produce a cloudy image on your lens.
  • Check the manual - If you want to take your Vortex binos apart for cleaning, always check the manual before unscrewing any important parts, not only could this potentially void the warranty but it could also damage the binos!
  • Use a lens cap - Always use the provided lens caps on your Vortex binoculars, this is super important to prevent them from becoming scratched.
  • Store them in their case - When you are not using your binoculars you should ensure you are storing them in a case to prevent them from dust and knocks.
  • Never over clean - As we mentioned at the beginning of our article, overcleaning your binoculars will ruin coated lenses causing them to wear off faster, only clean your binos when you need to.
  • Use the right cleaning products - A damp cloth with a cleaning solution is all you need for cleaning your vortex binos, never use paper products or detergent on lenses for cleaning as you can damage the ultra-thin coatings.
  • Make sure they are protected - Most Vortex binoculars are pretty rugged and waterproof as well as fog proof, but you should still take care when exposing them to harsh weather conditions and moisture, never take binoculars out on the field unless they are weather armoured. 

Final Words 

Overall, Vortex binoculars are easy to clean and maintain, just make sure you are using the right kind of cleaning equipment and you always use compressed air to get rid of any dust particles first. When you are not using your Vortex binos you should make an effort to keep them protected with a lens cap and storage case. 

Always clean them when needed and avoid excessively cleaning the coated lenses to increase their performance. 


Whats The Farthest You Can See With Binoculars?

Whether you want to stargaze, bird watch or view your favourite concert up close, binoculars can help us see objects close up from far away, but just how far can you see with a pair of binoculars? 

Well, you can see as far as you like with binoculars, but the real question is how much detail you can see on faraway objects, which is determined by the distance we can see with our naked eye, external factors and magnification level of your binos.

In our article below, we will go over all these factors that affect how far we can see with binoculars, as well as how far you can see with different binocular strengths and the longest range binoculars on the market. 

How Far Can Our Eyes See? 

Before we can get into how far powerful binoculars can allow us to see, we have to start with our own eyes.

Our normal vision has no limit when it comes to distance, humans can see any object as long as it is illuminated as a bright image, but the issue of human visions is that we cannot see these objects in detail. 

That is where binoculars come in, as they produce a magnified image with much more detail. 

For example, your normal vision can see up to 48 kilometres away while your power binocular could extend it up to 483km away.

Factors Affecting Viewing Distance

Not all powered binoculars produce the same level of viewing distance, it is affected by a range of different factors which have to be considered to begin with. 

  • Physical obstructions - When observing through your binoculars it is likely there will be an obstruction that can limit how far you see, this obstruction could be trees or other foliage.
  • The weather - High levels of air pollution or even just rain, wind, fog and smoke can reduce your viewing distance.
  • Binocular strength - A 10x binocular magnification will always allow you to see further than 8x binoculars as it magnifies the image 10x closer to you rather than 8x. High-powered binoculars allow you to see more detail the higher the power that you choose.
  • Objective lens - As a wider objective lens lets more light in, this will allow you to see images further away, objective lenses that have a 50mm size will allow you to see further than powered binoculars with a 32mm lens.

How Much Distance Can You See With Binoculars

Now we know the main factors that influence how far we can see with binoculars, we will cover the main powers of binoculars below and their magnification to give you an idea of how far you can see with each different powered binocular.

Binoculars tend to have a magnification power ranging between 6x and 12x allowing you to view images closer or further away, when you choose a higher magnification however you have to make sure you keep the image steady. 

Binoculars Strength

We will list the main magnifications that binos come with below and what they are used for. 

  • 5x magnification - These binos could see up to around 50 metres and are excellent for close up concert viewing or wildlife observation where you need to see detail but not too far away.
  • 8x magnification - You can see as far as you want with 8x magnification binoculars, their magnification is a preferred choice for bird watchers as you still get a wide field of view.
  • 10x magnification - These binoculars allow you to see an image 10x bigger and are the best choice for hunting or safari.
  • 20x and more magnification - You can view as far as the moon or start clusters with a binocular of this power, they have to be kept steady with a tripod, however.

How Far Can I See With 10x50 Binoculars?

A pair of 10x50 binoculars are pretty common on the market so you might just be wondering how far you can see with them. 

As we mentioned above, there truly is no limit on the distance that you can see with these binos, on a clear night with no obstructions and fog, you can defiantly make out stars and the moon, but they wouldn't be in much detail, for this you would have to consider going up to a magnification of 12x.

What's The Longest Range Binoculars? 

This brings us to the question of, what are the most powerful binoculars on the market which can allow me to see the longest distance with detail? 

There are two most popular strongest magnification binos on the market, 25x50mm and 30x60mm, both of these binoculars can be used to see faraway objects in better detail such as the night sky but will need a tripod.

Final Words 

Overall, there is no limit as to how far you can see with binoculars, the only limit is to how much detail you can see these distant objects in, higher magnification binoculars with a greater objective lens allow you to see a further distance as they magnify the image in more detail. Always remember external factors such as the weather or obstruction can limit this view.

Our Guide To Adjusting The Diopter On Your Binoculars

Buying the best pair of binoculars is a great start to getting the best image quality out of your optics, but not knowing how to set the focus and dioptre of your binoculars can produce a blurry image and limit your observation. 

The diopter adjustment on your binoculars refers to the refractive power of the lens, the higher the mm of the diopter than the stronger the lens on your binocular diopter and the more correction it will need. 

To adjust the central diopter on your binocular you have to shut either eye and adjust the image until clear, this will be different if you have a central focus system on your binoculars. 

We will cover more about the difference between the central focusing mechanism and dioptre focusing systems on binoculars below, how to perform the diopter adjustment on your binoculars as well as some troubleshooting tips if your image is still blurry after diopter correction. 

What Is Diopter Adjustment? 

So as we can understand how to set adjustable diopters, we have to understand what this part of your binoculars does first. The diopter adjustment knob on your binoculars is a one-off adjustment that allows you to calibrate each eyepiece of your binos individually for a more fine-tuned precise image. 

 The diopter adjustment barrel is typically located on the right eyepieces of most binoculars and is set up at the beginning when you buy your binos. 

What Is Central Focus Adjustment?

More people are familiar with the central focus adjustment on their binoculars which is located in the middle of their binoculars, this makes your image focus when turned, some of the cheaper binoculars only have a central focus wheel without a diopter but do not give the same level of vision correction as individual diopter adjustment does.

How To Perform Diopter Adjustment On Your Binoculars 

Using the diopter adjustment knob on your binoculars is a simple process and can make a big difference for image clarity and vision correction when set properly. 

We will cover how to use the diopter adjustment setting on common binoculars below but it does differ according to the pair of optics you are using, if you get stuck always double-check your binos manual. 

  • Step one - First of all, find the diopter adjustment knob on your binos, this will likely be on the right eyepiece, make sure you set the diopter adjustment knob to zero before we start focusing.
  • Step two - Close the eye that your diopter lens is on and look through the other eye, choose an object around 30 feet away then move the central focus wheel until you see a crisp image, choosing an unmoving object will work best for this task.
  • Step three - Now close the other eye and turn the diopter adjustment wheel till you see a clearer image again. 
  • Step four - After adjusting the diopter gearing you can now check your vision in both eyes and adjust the central focus wheel until you get the perfect focus image, repeat steps until achieved. 
  • Step five - Now everything is set you can use the diopter lock to keep everything in place, if your binos do not have this then you can mark it with a chalk line to remember when the optimal place is.

Tips For Fixing a Blurry Image On Your Binoculars 

Even after setting your focus and diopter adjustment you might still be seeing a blurry image through your binoculars, we have put together some common troubleshooting reasons as to why this might be happening down below to help you find a solution.

  • Check the eyecups - If you do not wear glasses then you should ensure the eyecups on your binoculars are twisted up out of the way, for eyeglass wearers they need to be set at the shortest difference to make sure they are not limiting your vision.
  • Make sure your binoculars are clean - Smudges and debris can build up on your binoculars lenses if you are not careful, causing a blurry image. To clean your binos properly you must never use a t-shirt, always use a proper lens cleaning solution and a microfibre cloth as well as some compressed air to get rid of any dust.
  • Check the distance between your barrels - Make sure that the barrels of your binos are aligned properly with your eyes at a proper distance, some binos automatically fold back.
  • Evaluate your distance to your subject - If your close focus range is limited then your subject might be too close, hence why it looks blurry, same goes for when your subject is too far away, your magnification might be too limited. 
  • Look at your prescription - It could be possible that your eyesight has changed, this can happen with age, always readjust the diopter and focus on your binos when your eyeglass or contact lenses prescription changes. 
  • Consider light conditions - When viewing subjects through your binos varying weather conditions such as fog and shadows can cause your image to look blurry through the lens even when it is set right.

Frequently Asked Questions About Binocular Diopter & Adjustment 

Do roof prism binoculars have diopter adjustment? 

Yes, roof prism and Porro prism binoculars both have diopter adjustment, some of the more advanced optics might have this on the left barrel with a diopter lock.

Where is the diopter range on my binoculars?

The diopter range is typically on the right side of your binoculars but can sometimes be in the centre too, your binos manual will always say where if you are unsure.

Is the diopter helpful for a sharp image on my binoculars? 

Yes, the diopter is very important for the best quality image as it calibrates both of your eyes individual differences. 

When should I change my diopter adjustment? 

The diopter on your binoculars is always changed when your first get your binos but only has to be changed again if your eyesight changes or someone else is using your binoculars.

Final Words  

To conclude, setting the binocular diopter is important if you want to get the most out of your binoculars, not only for proper focus but also for correcting the difference in your vision between each eye.

Some binoculars might have an all in one central focusing knob or no diopter adjustment at all depending on the quality of the binoculars, always refer to your manual for the proper settings if needed.

Our Guide To Viewing Saturn & Other Planets With Your Binoculars

There's nothing more satisfying than observing the night sky, seeing different planets, their rings and stars up close, but the question is, can you see this all with just a binocular?

Well, yes, you can indeed see the planets as well as Saturn's rings with a binocular, but this has to be an astronomic binocular which works well in low-light observation and has a strong enough magnification over 20x to see the ring definition.

To help you out we have discussed which type of binocular you need to see the planets below, which planets you will be able to see and how binoculars match up to telescopes for planet viewing to give you the best chance of seeing Saturn's rings.

What Type Of Binocular Do I Need For Viewing Planets?

If you want to be able to view Saturn's rings and other planets in the night sky, you have to make sure you are using suitable binoculars and accessories for the job. 

The best astronomical binoculars would need to have a strong magnification level of over 20x if you want to be able to differentiate the rings from Saturn. For the clearest images, you have to make sure that your binoculars have a generous objective lens size to allow light in when viewing deep-sky objects too.

Preferably, the objective lens size of your binocular should be anywhere between 50mm and 70mm to see star patterns and planets. 

You should make sure your binoculars have a decent field of view too for observing a wider portion of the night sky.

Which Planets Can You See With Binoculars?

Now we know the type of binoculars you need for viewing planets and Saturn's rings, you might be wondering what planets you will be able to view when observing. 

We have listed the most likely ones below. 

Mercury & Venus 

These two planets are astronomical essentials for observation as they are the closest planets to us and are easy to spot in the starfield, especially when they are passing between the earth and the sun. Venus can produce stunning images at twilight thanks to it being so bright.


Mars is typically in front of other star parties and is easy to spot thanks to its red bright planet colours amongst the largest moon. Even beginner telescopes and binoculars should be able to see mars without any issues as long as you know where to look.


When looking for Jupiter you will likely notice the four major moons close by which are the Galilean Satellites, Jupiter itself, however, can be hard for amateur astronomers and even professionals to see as it stays hidden often. A tripod will help in this scenario to keep you steady when observing.


Saturn itself can be seen in a night sky image with a golden colour, and if you have a high-quality pair of binos like Celestron binoculars for astronomy, you will probably be able to see Saturn moon, Titan, too in the telescopic image. 

Many people assume you need larger telescopes to see the rings of Saturn, but you might be able to see them with powerful binoculars too, this is not a guarantee, however.

Uranus & Neptune 

These planets might be the farthest away but are not impossible to see if your binoculars have a decent level of magnification. Uranus typically looks green while Neptune is more like a star, they are both very similar and you can always use a finder chart to locate them if you get stuck.


As well as these main planets, you can additionally view bright objects such as a star cluster, comets, asteroids and galaxies. Prominent belt stars can be easily seen with a decent pair of binos. 

Binoculars Vs Telescopes - Which Should I Choose For Planet Spotting?

Many people prefer to use a monocular telescope for viewing star parties and planets because of their greater magnification and tripods, but a good pair of binoculars can be equally as good for this purpose with the right specs and have many advantages too. 

We have compared both a telescope and binoculars below for this purpose to help you decide on which optical zoom is right for you. 

Binoculars For Astronomy 

Binoculars have the upper hand over reflector telescopes when it comes to affordability and portability, you can get compact binoculars with excellent magnification nowadays which fit easily into your pocket when on the move.

These devices are also better when it comes to viewing astronomy essentials such as a star cluster too and the night sky thanks to their wider field of view, not to mention you get a three-dimensional view of a bright star because of the two eyepieces!

Binoculars fall short when it comes to observing planets in isolation such as Saturn's rings due to their more limited magnification. They also tend to come without a tripod and let less light in that telescopes due to their smaller lens.


  • Affordable. 
  • Portable. 
  • Great for viewing stars with a wider field of view. 
  • 3D view.


  • Not as magnified for detail. 
  • Less light. 
  • Little stability.

Telescope For Astronomy 

Telescopes are much more favoured when it comes to astronomical viewing due to their higher magnification power and stability, most often come with a tripod or stand for a better viewing experience, they are more suitable for looking at planets or the moon in detail rather than a wide field of view. 

Downfalls of telescope targets have to be their high price and little field of view which is not as good for viewing a star cluster due to its narrower image, they are also less portable to carry around as you often need a stand.


  • Higher magnification. 
  • Better stability. 
  • Best for isolated planet and moon viewing in detail.


  • Less field of view for star cluster viewing. 
  • Not very portable. 
  • More expensive.

Which One Should I Choose For Seeing Saturn's Rings?

For viewing Saturn's rings in particular we would always suggest going with a large telescope. This will give you the best chance of looking at the planet in more detail, you can use binoculars for this but you would need a very high-quality pair with a good aperture for the best detail. 

If you are wanting a more affordable device to view the night sky with and view energetic stars and patterns, then a binocular could be the better choice. 

Last Words 

To conclude, you can see Saturn's rings with binoculars if you get a very powerful pair with a high magnification of at least 20x and a larger objective lens between 50mm and 80mm for the best light.

We would always suggest using a telescope for a better chance of seeing Saturn's rings but binoculars can be great for looking at the whole night sky in detail too. Never look directly at the sun with your binos or telescopes for your safety.

Our Ultimate Guide On How To Use Rangefinder Binoculars

If you are looking at a binocular for marine purposes, hunting purposes or golf then you will likely come across a pair with rangefinder reticles. 

Binoculars with reticle rangefinders will have either a marked reticle scale for you to work out how far away you are from a subject or a rangefinder laser light that sends a flash of light and automatically works out how far you are from a subject. 

In our guide below, we will cover which binoculars have range finders on them, how reticle range finders work and how to use them as well as how they match up to laser rangefinder binoculars. 

What Are Reticle Rangefinder Binoculars? 

First of all, let's explain what reticle rangefinder bins are. 

These rangefinder binos use a net of fine lines in the eyepiece of each binocular to produce a scale or they will have a type of reticle which are digitally displayed when you look through. 

Similar to a rifle scope, the scale on these types of reticle binos allows you to measure how far away you are from a subject or animal, they can also calculate the angle of a subject and the height of the target object. 

There are different types of measurements of objects on these reticles, but most use a mil-dot reticle to measure distance, so also have silhouettes you can use to get a guess on how far an object is away.

Where Are Range Finding Reticle Binoculars Used? 

Rangefinding reticle binos have several different uses and can be found mostly on - 

  • Marine binoculars - Having a reticle on a marine binocular allows sailors to identify their distance from other marine vessels, lighthouses and boats. 
  • Gold range finders - These types of range finders usually are on a monocular rather than a binocular and allows you to calculate the distance to a hole so as you can choose the perfect golf club. 
  • Hunting & military - On hunting optics as a reticle is used for helping you aim at potential targets by calculating how far away you are, more people are using quality optics with laser light for this in the professional field. 

How To Use Rangefinder Reticle Binoculars

If it's your first time using rangefinder binoculars you might be a little overwhelmed with all the measurements, but we have broken down how to use these marine binocular type systems below to help you out. 

Mil-Dot Formula 

To use rangefinder binos you will have to understand how to use the Mil-dot formula, this works as long as you know the height and length of the object you are spotting through the scale. 

For example, if you knew a building was 70 metres tall and your scale height says it's 90m tall then you simply divide 70 by 90 then times by 1000, this would mean the building is 777m away. 

Numerous spreadsheets already have their calculations on there to speed up the process.

What Are Laser Rangefinder Binoculars? 

As well as your reticle rangefinder binos, you also have laser rangefinder binoculars which are in the higher price range. To calculate the distance the laser system shoots out a flash of light at a target object then the distance is worked out by the amount of time it takes to reach the receiver. 

These binos are excellent for hunting and can spot animals up to 1000 yards away when calculating distance, they are not however good for use on water due to it being a reflective object. 

We have listed both the pros and cons of reticle rangefinder and laser rangefinder binos below. 

Laser Rangefinder Binoculars Vs Reticle Binoculars 

Since both types of rangefinder binoculars are so popular, we have compared both of the rangefinder systems below to help you work out which kind of rangefinder is right for you.

Reticle Rangefinder Binoculars 

Reticle rangefinder binoculars excel over their laser competition when it comes to range, they can be used to calculate longer distances and also are much more affordable. Not all of the models require batteries to function either. 

The drawbacks of these binoculars have to its calculating process which is a little more time-consuming and less accurate. 


  • Calculates longer distances. 
  • More affordable. 
  • Some do not need batteries.


  • Calculating process is time-consuming. 
  • Less accurate.

Laser Rangefinder Binoculars 

Laser rangefinder binos are very accurate on the other hand as they do not rely on human judgement and give a result immediately with no waiting time for calculation needed. 

They do however need a constant power source to run due to the laser and are very expensive. The total range this rangefinder system can calculate is more limited and inaccurate over water.


  • More accurate. 
  • Great for hunting. 
  • Instant result.


  • Not accurate on water. 
  • Needs a power source.
  • Expensive.

Which Rangefinder Binoculars Should You Buy? 

Overall, reticle rangefinder binoculars are the preferred option for most laser binos thanks to their affordability and longer range distance, however, for professionals hunting a pair of laser rangefinder binos could be worth the investment if you want the best accuracy possible.

Top Factors To Consider In Rangefinder Binoculars 

When choosing your rangefinder binoculars, there are some key features you need to keep in mind if you want to be getting the most out of your pair of binos when hunting or spotting. 

We've listed the essentials to watch out for below.

  • Maximum range distance - Rangefinder binos in particular will have a maximum range distance, this number will determine how far off your rangefinder will be able to calculate the distance of faraway objects. Laser range finders will be more limited with this distance depending on their light beam.
  • Data accuracy - Different rangefinder binoculars will give various support data to help with accuracy such as elevation angles, temperature readings, and coordinates, these types of binos are always the better choice.
  • Field of view - A large field of view for seeing distance is important and will be more restricted if you have binos with a higher magnification.
  • Magnification & objective lens - Depending on the activity, you will choose the magnification level and objective lens size of your binoculars, range finder binos tend to have a magnification of either 10x or 8x and an objective lens of around 50mm to let a decent amount of light in.
  • Lens coatings - Like other binoculars, your rangefinder binos should have fully-multi coated lenses for the best quality optics and to reduce colour fringing.
  • Design - Most rangefinder binos are for outdoor use, so your design needs to be rugged, waterproof and fog proof.

Frequently Asked Questions About Rangefinder Binoculars 

What does ballistic configuration mean? 

This allows you to input your measurements and also allows for more accurate distance readings compared to previous rangefinder binos.

How much do marine binoculars cost? 

Standard marine binos with a rangefinder are not too expensive and are around the £100-£300 mark. 

What does a reticle display do? 

These are what gives you your measurements when looking through your binoculars in the form of a scale.

What price do laser rangefinder's cost? 

They can cost anything between £300 - £1000 depending on the quality of the model you buy.

Last Words

To conclude, rangefinder binoculars are easy to use but might take more calculating if you buy a reticle version rather than a laser rangefinder pair. To use rangefinder binoculars you simply have to divide the height of an object by what the height of the reticle scale says and times by 1000. 

Our Fool Proof Guide To The Numbers On Binoculars

For first-time buyers of binoculars, the numbers can be a little confusing if you are looking for high-quality binoculars. 

The two numbers on a pair of binoculars refer to the magnification power and objective lens size of your powered binoculars, the greater the first number, the further you can see images, the higher the second number, the more light your binos allow for a brighter image.

As finding your pair of binoculars can be a little overwhelming, we have explained in more depth how these numbers work below and what number you should be looking for on your binos, we will also discuss the other numbers on binoculars and what they mean too. 

What Does The Magnification Number Mean? 

The first figure on your binoculars with the 'X' sign is your magnification, on most regular binoculars this will be between 8x and 10x but for expensive binoculars they can have an extreme sized zoom binocular size of 12x or even 15x. 

This would mean that types of binoculars with an 8x magnification would make objects appear 8x closer and so on. 

Depending on what you need your zoom binoculars for will determine the size of the magnification, we have listed some common magnification sizes according to the activity below. 

  • Theatres and concerts - For concert venues, you need a pair of binoculars that are compact and easy to carry with a large enough angular view for seeing the whole stage, therefore we would recommend any binos with a magnification of under 8x.
  • Bird watching & hunting - When birdwatching, you want to ensure that your binos have a wider field of view for tracking moving subjects, therefore your magnification level should be around 8x.
  • Hiking or travelling - In terms of hiking or travelling, binoculars with a 10x magnification level will be a versatile binocular and not too heavy.
  • Astronomy - For astronomy, your binoculars must have a high strength of magnification if you want to see planets and stars, this would be 15x or even 20x.

You should always remember that a higher magnification number does not always mean better binocular lenses, sometimes a larger magnification level will mean a lower angular field of view and would require stabilisation such as a tripod. 

What Does The Objective Lens Size Number Mean? 

The second number on your binoculars will usually be stated in mm and refers to your binoculars objective lenses size or aperture controlling light conditions in your image. 

If you go for binoculars with larger lenses, they will allow more light in and will be more suitable for use for astronomy or in low-light conditions. For example, a 12x50 binocular has 12x levels of magnification and a 50mm aperture. 

It is important to remember that wider lenses with more light are not always the better option and can make your pair of binos very heavy.

Other Binocular Numbers Explained 

Now we know what the main two binocular numbers mean we can get into looking at the other numbers which will be stated on your binos specs so as you can understand everything you need to be looking for in your new binoculars.

Field Of View 

The field of view on your binoculars is typically expressed per 1000 yards, it is a very important number as it determines a decent field of view through the lens which is essential in activities such as sport if you want to track moving subjects. 

Anything with a FOV of over 300ft is excellent, remember that this number will be limited if you have binos with a higher magnification. 

You may also see an angular field of view on your binos expressed in degrees, this refers to the same number as a field of view, any binocular with a 6-degree angular field of view and above is a good choice. 

Eye Relief 

For people who wear glasses, you must ensure that you look at the eye relief number on your binos before buying. Binoculars that have a small eye relief will cut off the image that eyeglass wearers see when looking through the lens, so the number should always be bigger in this case. 

Always look for an eye relief of over 15mm relief for eyeglass wearers.

Exit Pupil

Another number you will see on your binos is the exit pupil, this number refers to the light beam which comes out from each eyepiece and is typically measured in mm. 

This number becomes important if you are planning to use your binos in low light situations, as a larger exit pupil will provide you with the clearest images. 

On most binoculars, the exit pupil will be around 4-5mm, but if you can get higher up to 7mm this will be excellent for producing sharper images. 

Close focus 

Lastly, we have the close focus number, this number refers to the minimum distances that you can focus on something, anything around 2m is great, but it can be hard to find a low close focus distance on cheaper binos for the perfect focus. 

How To Set Up Binoculars

Figuring out the numbers for binoculars can be a little overwhelming as a first time binocular buyer but so can setting up your binos, with you having to adjust the dioptre and focusing ring.

We have put together a simply follow step by step guide below that will cover how to set your binos for the first time. 

  • Step one - First of all adjust the eyecups on your binos, twist them up fully if you do not wear glasses or set them at their lowest position if you do wear glasses for a better field of view.
  • Step two - Adjust the eye width of the bino barrels until you can no longer see black rings overlapping.
  • Step three - Take your binoculars and try to look at a subject at least 50 metres away, close your right eye then adjust the focusing ring until the image in your left eye is not blurry anymore. Then close your left eye and adjust the dioptre ring till the image in your right eye is not blurry too.

Frequently Asked Questions About Numbers & Binoculars 

What are roof prism binoculars? 

Roof prism binoculars have a more complicated internal system than Porro prism binos when it comes to the light, this often makes them more expensive but also compact and lightweight, making them a better investment if you want a pair of small binos that produce high-quality images.

Which objective lens size should I buy? 

The objective lens size of your binos by standard should be over 20mm and under 50mm for average use, this will ensure there is enough light in your image but will keep your binos a reasonable weight too.

Are lens coatings important? 

Yes, lens coatings are very important on your binos as they improve image quality and stop reflection as well as colour fringing.

How do I know which binos to buy? 

You should choose your binos according to what you will be using them for, for example, for hunting, you would choose 10x binoculars with a 42mm objective lens, lens coatings, waterproofing and a decent field of view.

What does the close focus number mean?

In some situations you may want to zoom in on a subject that is a little closer to you, the distance refers to how close this subject can be until your binoculars cannot focus on it anymore. Close focus is great when birding or hunting.

Is a higher magnification better? 

No, a high magnification does not equal a better pair of binos it simply means you can view subjects from further away, you will have to have binos with built-in stabilisation to stop the shakiness or a tripod when using highly magnified binos.

What are 12x binoculars good for? 

Some 12x binoculars would be excellent for long-range spotting or astronomy purposes when viewing basic stars and planets. We would not recommend them for bird watching or sporting events however as they would have a more limited field of view and a little blur when handheld.

Final Words 

Overall, the two numbers on binoculars refer to the magnification level and objective lens size that your binoculars have. It's best to choose a magnification according to the activity you will be using your binos for, and for the objective lens focus on how much you will be using your binos in low light. 

Always have an idea of the binocular numbers you want on your model before researching so as you can narrow down the most suitable models with ease for your purpose of use. 


Are Binoculars Okay To Bring To Concerts?

Concerts can be an excellent chance to see your favourite star on stage, but what happens when you are seated too far away and end up missing out on all the action on stage? 

That's why bringing a pair of binoculars to your outdoor concert or indoor concerts is a great idea, they allow you to zoom in on the action and have an amazing time even if you are seated at the back of the concert setting.

To help you find the best binocular choice for concerts we have composed a guide below which will cover why you should use binoculars at a concert, the essential features to look for in concert binoculars and some tips for using them in concert settings.

Why You Should Bring a Binocular To a Concert 

You might wonder if you are allowed to bring binoculars to a concert at all, usually, concerts have no issues with your bringing in your binos to the concert venue, but if you are not convinced, we have listed a few benefits of bringing your binoculars to an outdoor concert or indoor concert below.

  • It doesn't matter where you are seated - Even if you get seated on the worst seat at the back of your concert venue, with decent binoculars you can still see everything you need and have an awesome time.
  • You don't miss out on the action - As a concert attendee you can sometimes miss out on seeing your favourite star or band member if they are too far away or people are standing in front of you, but with binoculars, you do not have to worry thanks to their magnification.
  • They can be used in indoor and outdoor concerts - Incredible binoculars can be used for magnifying indoor venues thanks to their low-light imagery as well as outdoor venues as long as you get a pair of binoculars with better magnification.
  • Tickets are cheap - The closer you are to the stage the more expensive your tickets will be, so you can get away with choosing a cheaper seat at a distance and save money as you will see everything with your binos.
  • They are allowed unlike cameras - Most indoors concerts do not allow cameras inside of the venue but never have problems with binoculars.
  • You see things other people don't - Having compact binoculars allow you to see expressions and get a different experience from most other people who are at the concert.
  • They work great in low light - Thanks to the larger objective lens size in most concert binoculars, they work great in low light situations, you can always choose a pair with a larger exit pupil to make sure of this which we will get on to next. 

Main Features To Watch Out For In Concert Binoculars

If you are looking for the best pair of binoculars to take to a concert venue then you should be ensuring it comes with certain features, unlike your standard pair of binos, for a concert attendee your model should have more important specs such as a wider field of view, extra-long eye relief and a lightweight. 

We will list the top specs and features to watch out for in your concert binoculars below. 

  • Magnification - First off, you want to make sure you are choosing the right power of magnification for your binoculars, this can range between 8x and 10x, for outdoor concerts, we recommend getting binos with a higher magnification as you will likely be further away but for indoor concerts around 8x will be more than enough. Never get binoculars with an extreme magnification for a concert as this will likely be handheld and become shaky.
  • Objective lens size - The objective lens size can be anything from 32mm to 42mm for a dimmed concert hall as this allows more light in, don't be tempted to get a pair with a huge objective lens size as this will add a lot of weight to the binoculars which can lead to fatigue while holding them during a concert.
  • Porro or roof prism - When choosing your pair of concert binoculars you will be faced with a decision between porro and roof prism binoculars designs. Although expensive, roof prism binos are more desirable for concerts as they have a lighter weight, they are more compact and durable.
  • Field of view - The FOV that your binos come with is super important for concert viewing, this will be expressed per 1000 yards and the larger the better as it will enable you to see the entire stage without having to move the binos around all the time. 
  • Eye relief - A long eye relief is one of the most necessary features in binoculars as you will be using the binos for up to 4 hours or more which can give eye fatigue. For eyeglass wearers, this should be over 15mm no matter what.
  • Lens coatings - To have a fun time viewing a concert through binos, you should make sure the optics are of high quality, choose concert binos that have multi-coated lenses to remove any reflection and colour fringing and extra-low dispersion glass to produce better detail in low light.
  • Design - The design of your binoculars should be easy to hold and durable, you never know when they might fall out of your jacket pocket or get dropped. For outdoor concert viewing the design of your binos should be waterproof as well for any unexpected weather situations.
  • Weight - Do not choose binos that have a heavy weight for viewing concerts, this extra weight will make your experience less enjoyable as the binos will be handheld most of the time.

Tips For Using Your Binoculars At Concerts 

The objectives for concert binos are to be able to see everything on stage without having to have the best seat in the venue, but there are a few tips for using them at concerts if you want to get the most out of your experience. 

We've listed a few tips for using binoculars at concerts below.

  • Use the naked eye first - Zooming in on a subject at a concert is not always easy, use your naked eye to detect where you want to view first then place your binoculars over your eyes and view accordingly.
  • Wear the neck strap - A neck strap is very important to have as it prevents you from accidentally dropping your binos while observing.
  • Keep your binos with you at all times - Concerts are full of sweaty people, and you might place your binos down for one minute only to look for them again and find they are not there, keep your valuables close to you during these events.
  • Choose a higher-up seat - If you can, choosing a higher seat in your concert venue will give you a better vantage point to see everything.
  • Keep the lenses clean - Keeping your lenses clean will give you the best image, do not be tempted to clean them with your shirt, instead use a microfibre cloth and a lens cleaning solution.
  • Use them properly - Maintaining a good posture while using your binos is a good way to make sure you don't get fatigued, you should pull your shoulders towards your back to prevent hunching.
  • Have easy accessibility - Store your binos somewhere close to like in your pocket or around your neck, this will make sure you can get to them quickly when needed and not miss out on any action.

Porro Prisms Vs Roof Prism Binoculars For Hunting 

When finding quality hunting binoculars you will be faced with a choice of Porro prism and roof prism binos, both have their advantages and disadvantages with Porro prism binoculars often being the more typical choice. 

We will compare both kinds of hunting binocular types below to help you decide which type is best for you. 

Porro Prism 

Porro prism binoculars are the more affordable and old school binoculars for ease of use, they use two right-angled prisms which face one another and have an objective lens tube away from the eyepieces, this increases the light transmission seen in the image for better performance in low-light conditions. 

These types of binoculars offer ample magnification and a great field of view for bird watchers and scouting faraway animals.

The downfalls of Porro prism binos have to be their size which is often more bulky and heavy, they are also a little less durable than roof prism binos with less having waterproofing.


  • Affordable. 
  • Excellent in low-light conditions. 
  • Great field of view. 


  • Heavy. 
  • Less durable.

Roof Prism

Roof prism binoculars are the more modern type of binos and typically include two prisms that are separated by an air gap for a longer light path which helps with 90-95% light transmission. 

The expensive binocular model is much more streamlined to make it the better type of compact binoculars for hunting when you will be holding them for long periods

Negatives of the modern roof prism binoculars have to be their smaller field of view and high price, some also argue these designs have a poorer image quality.


  • Compact binoculars. 
  • Lightweight. 
  • Great durability. 
  • Better magnification.


  • Limited field of view. 
  • Expensive.

Conclusion - Which Type Of Binocular Should I Choose For Hunting?

To conclude, we recommend choosing a roof prism pair of binoculars if you are looking to do long-range hunting more often as the compact-style binoculars have great magnification and excellent image quality. 

However, if you can't afford it Porro prism binoculars are still a great choice for hunting, especially if you are after a wider field of view for tracking animals. 

What Magnification Do I Need For Hunting?

As well as working out what prism type of binoculars you need for hunting, you should consider the power of the magnification too as this will determine how well you can see the farthest objects. 

The magnification of your binoculars is the X number that you will see on the binos specifications, for hunting, you want a standard magnification of either 8x or 10x if you want to be doing target spot from a distance. 

Anything higher will be harder to keep stable when viewing images and will limit your field of view which is important for tracking animals when they are on the move. 

As well as the magnification you need to consider the objective lenses size too which is the second number, this is what controls how much light is seen in your image, with the bigger objective lens being better for low-light conditions. 

The larger your objective lenses size is when hunting the heavier the binoculars will be, however, so if you are looking for your binos to stay compact then you should ensure your objective lenses size is not over 50mm. 

Top Features To Look Out For In Hunting Binoculars 

Now we know the main points about choosing your initial hunting binoculars we can get into the essential specs and features you need to be looking for in your best hunting binos.

Not only do you need to be considering the power of your hunting binoculars but you have to make sure it has lens coatings and a durable design too. 

We will list the main specs to watch out for in your model below. 

  • Magnification - As we touched on above, the magnification for a good pair of hunting binoculars should be between 8x and 10x, any higher will cut off your field view and be hard to keep stable. 
  • Objective lens size - Your objective lens size shouldn't be too big or small to avoid added weight or poor-quality light in your image, the best objective lenses size is a standard 42mm for hunting. 
  • Exit pupil - In terms of hunting the binocular in question should have an exit pupil of at least 5mm, some mini - binoculars will have a smaller exit pupil which can make you see a darker image through your lens.
  • Lens coatings - Uncoated lenses should be avoided on high-quality hunting binoculars, fully multi-coated lenses or baK 4 prism coatings improve quality optics with their anti-reflection coatings which reduce colour fringing, improving observation and identification of animals.
  • Durability - Hunting binoculars, in particular, have to be very durable, they should be rubber armoured and have waterproofing as well as fog proofing to protect them against all kinds of elements. Your binos should also have some rubber gripping to ensure comfortable holding.
  • Weight - You want to avoid heavy binoculars when hunting, most of the time you will be on the move with your binos handheld and you do not want them to become too heavy to hold for longer periods.
  • Eyecups - The eyecups of your binos for hunting should have an eye relief of over 15mm for glasses wearers and be comfortable with the adjustability, eyepiece lenses are typically made with rubber to be more comfortable.
  • Close focus - A shorter close focus distance means modern binoculars can focus on subjects that might be closer than anticipated, this could be good for looking at close-up animals as well as insects. Around 2m is a great close focus range to look out for.
  • Field of view - For the field of view, your hunting binoculars will have this measured in either degree or per 1000 yards, the larger the FOV then the better your binoculars will be for tracking moving subjects, this will be more limited if your magnification is higher. A FOV of around 345ft is standard on most modern binoculars.
  • Accessories - Most decent hunting pairs of binoculars will have a few accessories included such as a neck strap, carrying case and lens covers to keep your binoculars secure and safe. Some may also have night vision which can be useful for tracking animals at night. 
  • Image stabilisation - If you are interested in buying hunting binoculars that have a higher magnification for faraway target spotting then you might want to get a pair with built-in image stabilisation, this will keep your magnified image still without you having to use a tripod but will come at a higher price. 
  • Warranty - No matter what, your binoculars should have a one or two year warranty for buyers confidence, cheap binoculars for hunting will often not have a warranty so check this beforehand.

Frequently Asked Questions About Binoculars For Hunting 

What durability features should hunting binoculars have? 

For hunting binoculars, your model should have waterproofing, fog-proofing and rubber armouring to ensure it's protected against any weather conditions or accidents.

Do I need a high magnification for spotting distant objects? 

No, a magnification of 12x or 10x is more than enough for spotting game animals at a distance, any higher you will need a tripod and they will not be as portable too.

What type of lens should I look for hunting in dark conditions? 

A lens with phase coatings and a larger objective lens of 50mm would be better for low-light observation, they may weigh more however as full-sized binoculars.

What do phase correction coatings do on binoculars?

Phase correction coatings on lenses are found on roof prism binoculars and are used for the correct difference in contrast and colours between each lens which is caused by the light splitting into each part of the binocular.

Porro prism binoculars do not need phase correction coating for a sharper image as they do not refract light this way.

How Do I Find a Pair Of Good Binoculars? - Our Ultimate Guide

There are so many kinds of binoculars on the market, whether you want a bird watchers pair of binoculars or expensive binoculars with art image performance. 

But you might be wondering, what makes a good pair of binoculars? 

Well, a good pair of binoculars typically have to use good quality glass optics, as this is what creates the intensity of the image you see. However, premium binoculars also have a whole range of other features too which make them top spec.

So in our guide below, we will cover the main points as to what makes premium binoculars and what factors you should consider before investing in a pair, we have also thrown in a short care guide to keep your high-quality binoculars in the best condition.  

What Type Of Binocular Do You Need?

Before we can get into what makes good binoculars we should go other the specs you need to consider beforehand so as you can be sure you are choosing the right pair. 

There is a huge range of binoculars to choose from when talking about the initial types, from roof prism binoculars to Porro prism binoculars, as well as night vision binos

We will go over these main two types of premium binoculars below to help you decide on the humble binoculars for you. 

Roof Prism Binoculars 

Roof prism binoculars are the more modern version of Porro prism average binoculars, they are more sleek and compact having a streamlined design which makes them lighter binoculars too. 

These compact-style binoculars however have a more complex internal lens system that produces a brighter image than Porro prism models making the high-quality optics a little more expensive.


  • Lightweight. 
  • Compact choices of model. 
  • Better high-contrast optics.


  • Can have a narrow field of view. 
  • Expensive price. 

Porro Prism Binoculars 

Porro prism binoculars on the other hand are the old school version of premium binoculars that sends light from your objective lenses through a pair of triangle catchers which inverts the light to create an image seen through the lens. 

Although this design does make the heavy binocular a little bulkier, it is easier to fix thanks to its simple mechanism and are often more affordable binoculars. They also have great, high-contrast images and a wider field of view than roof prism binoculars.


  • Great 3D imaging. 
  • Affordable price. 
  • Wide field of view. 


  • Bulky. 
  • Lower magnification.

Which Type Should I Choose?

Overall, for long-range spotting and daytime use, we would suggest going for the more expensive roof prism binoculars, however, if you want binoculars for birding or short-range spotting, then the more affordable Porro prism binoculars might be the better choice with their wider field of view.

What Size Binocular Do You Need? 

Not only does the different type of binocular determine how good they are, but so does the two numbers that determine their size. 

When choosing a good pair of binoculars you have to ensure your getting the right magnification level and objective lens size otherwise your binos might be of no use. 

Binoculars come with two numbers to determine their power, the first number with the 'X' symbol refers to the magnification that your binoculars come with.

A higher magnification over 10x is great for purposes such as astronomy but will be harder to get good image stabilisation, it will also limit your field of view.

The second number refers to your objective lens diameter, this shows how much light your binoculars will let in through the lens which can help them work better in low-light conditions. 

We've listed the ideal binocular sizes to pick based on activities down below. 

  • Sporting events - For sporting events, any sizes between 7x25 and 10x50 are a great choice that will keep your binoculars compact and keep a wide field of view too. 
  • Bird watching & hunting - We recommend a 10x42 to a 12x52 pair of binoculars for birding and hunting, this allows you to magnify well for tracking subjects but still will not limit your FOV too much. 
  • Marine - Binoculars with a power of 7x40 and 8x42 are great for marine binos, these should be waterproof and have durable rubber armour too for outdoor water use. 
  • Astronomical - If you are looking to zone in on the night sky then your binoculars need to have a pretty high magnification of over 15x and an objective lens of over 50mm.

Steps For Choosing Your Binoculars 

We will get into what features make a good pair of binoculars next but we will briefly go over a few steps to keep in mind for choosing the right pair so as you can be sure your binos will be the right ones.

  • Decide your price - Spending more on binoculars will often give you a better intensity of the image in the long run, but you can also find some pretty good binoculars in the lower price range too which don't compromise on image quality, this might be at the cost of weight, however.
  • Choose a power - As we mentioned above, what makes binoculars good are if they are suited to your purpose, so you must ensure that the model you buy has the right magnification as well as objective lens size.
  • Test some binos - So as you can get a feel for what you want, you should try testing out a few different binoculars first so as you can know the type of binoculars that you want, this will also help you decide the prism style and power.
  • Check the reviews - Checking the reviews of your binoculars beforehand is important, some binos might be heavier than stated or have faulty accessories, so knowing what your getting beforehand will determine how good your binoculars are. 
  • Consider the important specs - What makes binoculars good are their specs, some important wants you should always check are the eye relief for eyeglass wearers, the field of view, magnification, close focus and weight.
  • Look for a bright image - No matter the prism design or price, a brighter image is what makes binoculars good, so ensuring your model has multi-coated optics is one way to get a good image quality.

What Features Make Good Binoculars? 

Determining what makes a pair of binoculars good is down to preference, but there are some important features to make sure your binoculars have if you want the best pair for observing. 

We've listed the essentials to look for which make binoculars stand out over others below. 

  • Magnification -The first and most important feature that will determine if your binoculars are good is how far you can see with them, some people assume the higher magnification the better, but this is not always the case is will be harder to hold and limit your image width. Going for a 10x or 8x magnification is suitable for most people, but for astronomical views in the sky, you might want something higher around 12x or 15x.
  • Objective lens - Your objective lens size will allow more light for a brighter image, by standard a good pair of binos will have a diameter version of around 42mm but higher options are available too, however, these will add extra weight to your design.
  • Exit pupil - The average binoculars should have an exit pupil of about 4mm but they can range between 2mm and 7mm too, some lower light binos might have a larger exit pupil.
  • FOV - Field of view refers to how wide you can see through your lens, this is typically expressed per 1000 yards in most binoculars but can also be said in degrees. Higher magnification will limit your FOV so bear this in mind when choosing your binoculars. 
  • Eye relief - If you wear glasses the eye relief of your binoculars are super important, the higher the eye relief is the better as there is less risk of it cutting off the image you see at a distance. The eye relief on your binoculars should always be over 15mm.
  • Close focus - You never know when you might want to view an object up close as well as far away, this is where the close focus distance is important, as it will allow you to focus on objects such as feathers that are near you. The best close focus distance for binos is around 2m.
  • Lenses - The lenses are the most essential spec of your binos, whether you want lenses for bird watching or sporting events. This determines how much detail you will see as well as colour, so extra-low dispersion glass lenses tend to be used on the best binoculars. 
  • Lens coating - Not only should you consider the type of glass lenses used in your binoculars but you should additionally look at the lens coating. Lens coatings help stop your image from fringing and give a sharper view, the best type of glass lenses to watch out for are Bak-4 prism coatings or fully multi-coated lenses. 
  • Eyepieces - The eyepieces around your binoculars should be comfortable to use for long periods, for people who wear glasses have eyepieces lenses that are adjustable or can be twisted up is very important too. 
  • Focus mechanism - Most good binoculars will have an easy centre focus mechanism but some of the cheaper binoculars might not have this at all, this focusing should be quick and easy to set for any user.
  • Design - Outdoor binoculars need to have a durable design for activities such as birding, your binoculars should have rubber grips and be armoured in case of any dropping. The best binos have nitrogen filling too so as they can stay fog proof and waterproof.
  • Weight - Depending on the type of binoculars you buy, some can get pretty heavy, and you need to ensure your binos are lightweight compact-sized binoculars if you are going to be holding them for long periods during activities such as birding.
  • Night vision - Night vision is a great extra feature to look for in good binoculars if you are into hunting or viewing wildlife at night, not all binoculars have it but some of the higher-end models will.
  • Accessories - Some accessories which make good binoculars are a carry case, neck strap and even a tripod, some of these will be included depending on the value of your binoculars.
  • Warranty - No matter what, your binoculars should come with a one-year warranty for buyers protection, this also shows the binoculars manufacturer is responsible and reputable.
