Whether you are hiking or going wildlife viewing, a monocular is an excellent tool to add to your gear. Monoculars are often used by hikers, bird watchers, and nature enthusiasts to observe animals or parts of a landscape in the distance. With the best monocular, you will be able to see things in the distance with a great level of clarity and detail.

Monoculars are an excellent alternative to binoculars and telescopes because they are smaller, and lighter making it easier for you to pack them with the rest of your gear when you go on a hike. Small enough to be stored in a pocket, monoculars are strong enough to still provide the viewing distance you need. With spotting scopes, you can easily survey your natural surroundings which can make your time in the great outdoors more enjoyable.

To make it easier for you to choose from the wide range of monoculars available on the market, we have created a list of the 10 Best Monoculars in 2022 and we have included a buying guide to help you understand what makes a good monocular. Check out our list below to find the best monoculars for your needs.

How To Choose The Best Monocular – Buying Guide


When you are deciding which monocular to buy, it is important to consider a few key features. There are many different options available for you to choose from and you will need to decide which monocular design best suits your needs. From the style to the magnification, there are elements of each design that can enhance your viewing capabilities in the outdoors.

Monoculars can be used for a variety of different tasks and activities. Whether you are observing for leisure or working in the field, spotting scopes can be an excellent tool to add to your gear. It is best to consider the different designs of each monocular and ensure you choose a monocular that best suits your needs.

Below we have created a guide of some key elements of a monocular’s design that you should take into consideration before making a purchase. With our guide, we hope to give you the ability to confidently choose a monocular design for you.


There are a couple of different ways monoculars are sized. The first size factor is the physical size of the device and how large it is in your hand. The second is the size of the lens. Finally, the third is the size of the magnification. The second and third aspects of a monocular’s size will be expanded in their own section below.

With a monocular, you will be saving space when packing your gear. Monoculars are not doubled like binoculars, which means they are less bulky and will allow you to save space. Monoculars are a great way to bring a smaller viewing device along on your outdoor trip.

The majority of monoculars that are often chosen for use when hiking or fishing or bird watching, are a physically smaller and manageable size. Most monocular designs will be easily carried in one hand and stored away in a small pocket of a jacket, pants, or bag. However, there are larger monocular sizes available, so it’s best to consider how powerful of a lens you would like, as this will determine the physical size of the monocular device.


There are many different types of monoculars. The type of monocular is usually determined by the features it has within its design. Four of the most common monocular types are the infrared, thermal imaging, compact, and night vision.

Infrared monoculars use a different wavelength of light for better night vision. The wavelength, infrared, can illuminate night images and is often used for a night vision monocular. The best night vision monocular design (that uses infrared) will have the ability to switch the use of the infrared on and off. This allows you to use the monocular in both the daytime and nighttime. This type of monocular is often affordable but may not be best for hunters and observers. Some infrared monoculars have a red light that is visible when facing the lens, which may disturb animals.

Thermal imaging monoculars are a different type of night vision monoculars, which work by detecting and imaging the heat given off by an object. The heat is mapped to develop the image and they are normally sensitive enough to map people, animals, and rocks that are still hot from the day’s sun. The benefit of this monocular is that it can be used during both the daytime and nighttime without needing to switch modes, like with the infrared monocular. This monocular also does not give off a red light and can make animals easier to spot at nighttime.

Compact monoculars are even more compact than the generally compact monocular design. Most spotting scopes are compact when compared to other viewing devices like binoculars. However, some monoculars feature an extremely compact design. Compact monoculars are normally a few inches shorter than a standard monocular design and can be easily carried with you every day in every situation. To obtain their smaller size, most compact monoculars will have a smaller magnification and lens diameter. These may not give you the detail of larger monoculars when viewing things at distances because of their smaller design. But compact monoculars are still excellent at providing clear images for activities such as concerts or sign reading and are normally more affordable.

Night vision monoculars are used primarily at night to be able to see objects in the dark. The night vision monocular usually offers a choice between the infrared and thermal vision monoculars, which are each described above. Most designs also allow for daytime use as well. Ultimately it comes down to your choice whether you prefer to use infrared or thermal imaging.

Objective Lens Size

The objective lens size determines how much light can get inside of the monocular viewing device. The larger the lens is, the more light can get inside. More light inside means you will have a clearer picture when using higher levels of zoom. The allowance of more light entering the lens also means you will have a better picture and better use during dawn and dusk. Keep in mind that the objective lens size will change the physical size of the monocular device. The larger the lens is, the larger the body of the monocular device has to be. If you are looking to save space, the notion of ‘the biggest lens for the best picture’, may not be best for you. If you are looking for an extremely high powered monocular, you should look at other devices, like a spotter scope, which may better suit your needs.

Magnification Power

This is the most important feature of a monocular device because it is the real reason that adventurists want a monocular in the first place. The entire function of a monocular is to be able to see things that are far away as if they were right in front of the user’s eyes. The image should also be crystal clear.

The measurement of the magnification power is usually stated in a range from 4-25 + power. This means that when you are looking at devices, the power is represented with a number and x, like 6x or 20x. As the magnification increases, the field of view will decrease. This means that you will have a narrower field of view and the viewing window will be smaller. The higher the magnification power, the stronger the power is of the monocular device. Remember that high power monocular devices are pricey. The higher the magnification power, the more expensive it will be.

Field of View (FOV)

The field of view is the size or the lens diameter of the window that you can see when using your monocular. If you see a monocular device listed as 20ft and 20x, it means that you will have a viewing window with a 20-foot diameter and a viewing power of 20 times. As the magnification increases, the field of view will decrease.

However, the field of view can be affected by other features of the monocular such as the prism type and objective lens size. A high power monocular that has an excellent and expensive high zoom lens will have a better field of view than a model that has a high zoom but lower quality lens.

Prisms (Internals)

Spotting scopes are able to work and create their image using prisms which are internal, i.e. in the device. All monocular designs work off the basic idea and physics of a prism. A monocular works by passing light through the lens which is then passed through the prisms. Using both the lens and the internal prisms, a monocular is able to create the image of an object that is far away, as if it were closer to you. Depending on the distance of the object and your location, some objects can seem like they are just inches away from you.

There are three types of prisms that are normally used in monocular devices. There are roof prisms, porro prisms, and Galilean. A roof prism has more of an odd shape than the traditional triangular shape of a prism, and they have two faces that meet at a 90-degree angle.

A porro prism uses reflection and is in the shape of a triangle. Some porro prisms are a single prism and others are double. Roof prisms are best used with long ranges and would be an excellent choice for a high power monocular. Porro prisms are better with mid and close-range objects. Galilean monoculars work on the same concept as other prisms, but they are best used with close-range objects.

Lens Coating

A lens coating is what is placed over the lens to assist in tasks like shedding water, increasing image visibility, and preventing the accumulation of fog. There are many different types of lens coatings. The four most common types of lens coatings are coated lenses, fully coated, multi-coated, and fully multi-coated.

A coated lens is minimal and inexpensive. It provides a slight improvement to the image, which it would not be possible if there were no coating present. This coating is the most inexpensive of all coatings.

A fully coated lens brings another level of image quality that is one step higher than a coated lens and is just slightly more expensive than a coated lens.

A multi-coated lens will use different lens coatings on the same lens to deliver a superior and high-quality image. The price of these lenses will increase rapidly, as they are not considered to be part of a “budget” monocular price range.

Fully multi-coated lenses have the highest quality coating and are top of the line. This type of coating will give several different coatings to the lens which will help the lens absorb light. These coatings will increase the image quality and visibility, as well as create a crisp image. Monoculars with these lenses will be the most expensive.

Inert Gas Filled Monoculars

Inert gas filled monoculars are extremely high-end devices, which are rare and expensive. Some high-end monocular devices are filled and sealed with inert gasses. An inert gas is a gas which does not undergo chemical reactions when under a set of given conditions.  A sealed lens also means that the device is sealed from water and dust entering inside unless there is a malfunction.

Inert gas filled monoculars will have a better image because the light won’t be split, reflected, or refracted by the inert gasses. Inert gasses are still rare and expensive, but they are becoming more common. For now, it is a feature that is best used by professionals and with extremely high zoom lenses.

Waterproof Rating

The waterproof rating of a monocular is an important key feature because your device will not work if water makes its way inside. If water were to get into your monocular it would cause a poor image and fog over the lens, and it could lead to the complete failure of the device.

The best monocular will have a waterproof IP rating. The IP rating uses IP and then two numbers to indicate how waterproof the monocular is. For example, you may see an IP rating that says IP76. The first number is rated between 1 and 7. The higher the number, the more protected the device is, with 7 being the maximum. The second number is rated between 1 and 9 and like the first number, the higher the number indicates more protection. The first number of an IP rating indicates how resistant to dust and debris a device is. The second number indicates the water resistance. In general, any rating that is above IP56 is a good choice for a monocular.

Eye Relief

Eye relief is the distance of how far from the rear lens your eye must rest to create a clear image. This is normally measured in millimeters, though the distance can be a large range. For users who do not utilize glasses, a 10mm-20mm range is the most common. You can adjust the distance by using the eyecup. If you have glasses or simply don’t prefer to have the monocular close to your eye, look for a monocular with a longer eye relief or distance needed between the rear lens and your eye.

Focus Adjustment

A focus adjustment is an extremely important feature in order to achieve a clear picture. When you are looking at objects far away, you often will need to adjust the focus to make the edges sharp. If a monocular does not have a focus adjustment, you should look for one that does. Nothing can be more frustrating than being unable to obtain a clear picture. Some monoculars can be adjusted using one hand and others using two. Some designs have a knob that is used to focus, and others feature a wheel around the body. It is up to you to decide your preference for what kind of focus adjustment you would like.



Q: What is a monocular?


A monocular is a magnifying viewing device. It allows you to view objects in the distance as if they were closer. A monocular has the same concept as binoculars, but instead of having viewing lenses for both eyes, it is used with only one eye. This means that a monocular is a tube-shaped device, much like a telescope, though it does not expand and collapse. Monoculars are more compact viewing devices that can be great for many outdoor enthusiasts who would like to observe nature a little more closely than they would be able to with just their own eyes.

Q: What is the difference between binoculars and monoculars?


The main difference between binoculars and monoculars is how many eyes you use. Binoculars are designed with a viewing lens for each eye. This means that you will have two tubular shapes with lenses inside that make up the binocular body. The tubes will be connected with a joint and have different features to allow you to obtain a clear picture. A monocular is used with only one eye. You will have one tube-shaped device that has one rear lens for your eye.

Though they use the same technology and principle, monoculars are an excellent choice because they are more compact than a pair of binoculars. Monoculars are extremely convenient to bring along because they can be tucked away in a pocket and used with one hand. Monoculars are great if you would like a viewing device but want to save on space when packing your gear.

Q: What are monoculars used for?


Monoculars are very much like binoculars and can be used for anything you would use binoculars for. This means there are a variety of outdoor activities where a monocular could be useful, helpful, or fun. You can easily take monoculars hiking, fishing, hunting, bird watching, tracking, or other outdoor adventures. Monoculars can also be used in urban settings easily. You may find them helpful when attending a concert or reading distant signage. Monoculars can be a great tool that gives you the ability to view things in the distance with ease. Monoculars have a variety of uses for a variety of people. They are an excellent tool to add to your collection of outdoor gear.
