Best Night Vision Monocular for Hunting [Buying Guide]

night vision monocular reviews

When looking for the best night vision monocular, you should inspect every detail. Literally everything can affect your satisfaction with this device. However, there are some features that are more important than others. These criteria and specifications heavily affect the device performance. Those include magnification, field of view, size, weight, transmittance, lens type, lens coatings, photo/video mode and quality, power source and accessories. Also, let’s not forget about the warranty. Let’s learn more about these features.

1. Magnification & FOV

You will usually encounter 3x or 6x magnification models. Don’t go for better magnification before rethinking this decision, as it can compromise the image quality.

Also, FOV and magnification are interconnected. Simply put, higher magnification will result in a narrower FOV. Vice versa, lower magnification implies a wider FOV.

2. Size & Weight

Depending on your area of application, the size and weight of the device can be either very important or totally unimportant.

3. Transmittance

Transmittance is a technical term that describes the amount of light transmitted through the device. It is expressed in percentages. Type of lens, coatings and the construction of the device affects the light transmittance. Better light transmittance implies better image clarity. You should go for at least 90% transmittance.

4. Size of the Primary Lens & Lens Coating

Primary lens size is always denoted by the second number on your lens mark. For example, if your lens says 6x50mm, the size of the primary lens, i.e. the lens diameter is 50 mm.

It affects the width of the field of view. Also, it directly affects the image clarity and brightness.

Lens coatings should provide the anti-glare protection. You should go to multi coated or fully coated monoculars.

5. Focus

Focus is one of the most important features of a good monocular. Go for high close focus because this will work best with high-quality magnification and quality lenses.

6. Compatibility With IR Illuminator

If your night vision mono is compatible with an external IR illuminator, you’ll have better clarity and range. This will particularly be helpful if you possess a low-quality device.

7. Extra Features

In terms of versatility, these devices can offer tons of features. Engineers and developers devoted years to bring them to today’s precision. If your sole purpose is to watch objects and things in low light conditions, you might just do fine without them. But again, who doesn’t like more when it comes to technology? The most common advanced features are the ability to record video, photo, and audio in realtime.

Apart from them, some models will offer a higher resolution of photo and video. You might find AV out, LCD screen, and slots for Micro SD memory sticks. These will help you remain synced with your smartphones and desktops. Mounting options can help you enjoy views hands-free. When you mount your device, the view is much stable and the image video record in it should be less noisy and clearer.

8. Photos & Videos

Depending on your need, you might prefer the monocular which enables you to take photos and record videos, even those with sound. If you opt for such devices, you should go for HD quality. Also, analyze the connectivity and memory features of such devices.

9. Power source (Battery Life)

Battery life is an important factor to consider. You will definitely want a very good battery life, as these devices are used outdoors. Most of the devices use standard AA batteries. Some of them use rechargeable batteries, which is also very convenient. Advanced models can be charged with portable power banks.

10. Warranty

As these devices are not cheap at all, especially if we are talking about gen 2, 3 (and, obviously, the rare models we mark as gen 4), you should definitely not buy a monocular that comes without a warranty. Serious manufacturers will provide you at least 2 years of warranty.

11. Accessories

Accessories are not the decision-making feature, but they sure are useful. If you get a hand and neck-strap, a carrying case, batteries, and a lens cloth, you will be more than satisfied with your package. In addition, if you get some USB and TV cables, that’s great!

Why Use a Night Vision Monocular

cheap night vision monocular

A night vision monocular (also known as NV or NVG monocular) is a single eye-piece device used to detect the target/object at night. It shows its clear image and position through a mono glass setting unlike the binoculars where they use dual-glass structure. Therefore, its area of application is very wide.

You should definitely get one if you are a hobby or a professional wildlife observer, if you go camping, hunting, playing sports at night, such as golf or shooting, or if you need any kind of safety observation at night. In addition, police officers and different military operation participants benefit from using night vision monoculars.

How can you choose the best nightvision monocular? This depends on your needs and area of application. This is why it is very important to learn more about the principle of work behind a monocular.

How Does a Night Vision Monocular Work?

The basic principle behind monocular devices is collecting light particles and magnifying them in the optical parts, mainly prisms, of the device. This process may sound simple, but it is actually very complex and light passes through different parts of the monocular in order to produce a magnified image, intensified and high-quality image visible to the human eye.

In other words, night vision devices like monoculars transform electrical particles that we cannot detect with the naked eyes into images that we can see.

Two key processes behind the monocular work principle are thermal imaging and light amplification. These are actually two different ways that produce different results.

First, thermal imaging is based on measuring the amount of heat. Heat can come from animals, people, or objects. Some monoculars are based on thermal imaging, not on optical imaging. These devices have a built-in microbolometer sensor. It serves to read the heat difference between an object and its surroundings.

Secondly, light amplification-based devices amplify the light. This is how a clear image is produced. This is why these devices need an intensifier tube.

Of course, Monoculars, which exist for already more than 50 years, differs in sophistication. There are still older models as well as the new ones based on state-of-the-art solutions. Let’s learn more about the generations of monocular devices.

Generations of Night Vision Monocular

Generation I

Devices that belong to the Generation 1 Monoculars are usually less effective than gen 2,3, and 4 devices. This especially refers to image clarity. As a result, they are very affordable.

When it comes to technical features, you can expect light amplification up to 900x, a rather short battery life, range up to 75 yards, and you will need the IR.

You should get this kind of device if you want to use it for casual environment observation or Airsoft.

Price range varies from 100 to 250 dollars.

Generation II

Generation 2 devices are much better than gen 1 when it comes to object detection, recognition, and image clarity. The good thing is: they are still rather affordable. These devices are often used by law enforcement. At the same time, lots of them are used for hunting and hobby purposes.

Their key peculiarity is durability and good housing. They are also usually weather resistant. Light amplification is up to 30,000x. Battery lifetime is also increased when compared to gen 1 devices.

When it comes to prices, you will have to pay at least $1,000 dollars for a decent gen 2 device. This is a good price if you take into account the level of detail provided by these devices.

Generation III

Generation 3 devices have an even better image clarity than gen 1 and gen 2. In addition, recognition, level of detail and range are significantly improved.

Gen 3 is the minimum you should buy if you need a monocular for security reasons, such as surveillance and special operations.

However, these improvements come with a significant price increase as well. You will have to pay at least $2,500 dollars for a nice Gen 3 model. However, these are some of the top rated nightvision monocular models.

Generation IV

Generation 4 optics are not easily found. These are the most upgraded versions that exist today. They are rather rare and among the users. These devices usually have gated image intensifiers and are very expensive.

In return, you will get very clear images, excellent magnification-quality balance and state-of-the-art features, making it possible to get detailed images of objects even under cloudy skies or a new moon.

Prices start from $4,000 dollars.

Considerations Based on Your Intended Use

When choosing night vision devices, your key consideration should be based on your intended use. We cannot say that one type is better than the other if we don’t know the area of application. Some models are great for hunting while others are perfect for surveillance. There are those specifically designed for nature and wildlife observation, while others provide excellent results in dynamic environments while the user is running or moving.

This is why you should focus your purchase on the intended use. Let’s learn more about different areas of applications of these devices.

1. Tactical & Hunting

If you are looking for a monocular for hunting, you should look for a model that provides good target detection and detail level. You definitely don’t want to confuse types of animals or hurt them.

2. Observation & Surveillance

Models for observation and surveillance should have the video-recording feature with very good image clarity and quality. In addition, don’t expect to find such a model in gen 1. This also means you will have to spend at least 1,000 USD for a decent surveillance device like this one and even more for a night vision binocular. You should also go for a model that can be mounted on a tripod and has good connectivity options. There are also models that allow being mounted on your head or on a helmet.

3. Auto-Gating Unit

Auto-gating implies that reduced power usage at bright light conditions. This means that the tubes will have a longer lifetime. The damage is much less. Therefore, you should opt for these devices if you will be using your monocular in conditions with occasional bright lights.

4. Magnifiers

Magnifiers provide extra power which is good if you need your monocular for special observation purposes.

5. Video Feed

Video feed option is excellent if you want to use the device as surveillance and observation device. You can connect the device to a screen or multiple screens and observe the situation comfortably.

6. IR Illuminator

IR Illuminator is a very important part of your monocular functionality. Some models have a built-in IR illuminator, while others don’t. You will have to buy it separately if your device doesn’t have one and you want to use it in total darkness. Most models are compatible with standard IR illuminators.

7. Budget

Budget is another consideration that will heavily affect the type and quality of the device you will get. Usually, the more money you invest in, the better the quality you get. However, there are some exceptions to this rule and you can find some excellent choices at affordable prices. You should always pick these devices based on your own preferences and needs. By the way, the prices of our top 10 list are under 1000 bucks.

Monoculars are not the only type of night vision devices used for different applications. There are several useful, common types. Each one of them has their benefits. Let’s take a quick look at the peculiarities of five different types of NVDs.

  • Monoculars

Monoculars are compact, lightweight night vision devices mostly used for inspecting and security reasons. They have a single objective and single eye-piece.

  • Binoculars

Binoculars are great because they combine magnification and night vision. This is why they are mostly chosen for precision operations, including military purposes, land and sea navigation, as well as shooting and hunting at night. They are also very good for military grade surveillance purposes.

  • Goggles

Goggles are NVDs you need for a hands-free night vision experience. Although you might have questions as to their giving green vision, you may love them when effortless hunting is all you want. Also, many people playing paintball at night opt for goggles.

  • Cameras

Cameras for night vision are needed for taking videos and photos. That’s why they’re mostly used for security reasons and making videos of nature at night.

  • Eyeglasses

Night vision eyeglasses are great for driving at night or in foggy conditions. They significantly increase the safety of all traffic participants.

You can also share your experience with us using the comments section you will find below.


1. Can I use a night vision monocular during the daytime?

Ans. The name says it all – night vision. There are some digital models that you can use during the day but this could result in severe damage to the optics.

2. What’s better – night vision or thermal?

Ans. Of course thermal imaging is way better in terms of detecting and recognizing game. But they are relatively new in the industry while night vision has been available since WW2.

3. How far can I see with a night vision mono?

Ans. This will depend on many variables, such as the size of the object you’re aiming at, the amount of light present in the environment, the Gen that your mono belongs to, and so on. You can easily detect a person 300 yds away.

4: Does night vision work in pitch black?

Ans: The absence of light particles is almost impossible on earth. This is why night vision monoculars work even in apparent pitch black situations. On the surface of the earth, during the nights, you receive lots of visible light particles that can be used by these devices. On top of that, invisible light frequencies are also made viewable by advanced NVGs.

5: Does night vision work underwater?

Ans: Theoretically, an NVD should work underwater. But first, you’ve got to make sure that the device is waterproof. Not every NVD has waterproofing features and that’s why not all of them will work underwater.
