How To Select The Right Thermal Scope?

Thermal vision is the advanced means of weapon optics that uses a unique method of heat identification instead of seeing the light. Though being introduced not so long ago, thermal vision devices are widely used in military service, surveillance services, sport shooting, and hunting. In all application areas, they are the ultimate tools for better performance and results. Being expensive, they do not compromise the quality. This guide will tell you the basics about thermal scopes, and you will finally get this garget to serve your purposes. 

What is a thermal vision?

Here is a short description of how do thermal scopes work. Thermal vision devices portray an object using the temperature. A thermal imager is an electronic device that takes an image in the infrared range. A human eye cannot identify the heat, while a super-sensitive camera sensor captures thermal radiation and converts it to a heat map. 

The visible properties of the object are hard to see in bad weather. They cannot be identified easily when hidden behind the trees or camouflaged. In this case, heat detectors will help. Today, this complicated but functional device is a crucial component for efficient hunting and shooting activities. 

When you need thermal imaging devices?

If you still have not researched why a thermal vision scope is better than night-vision equipment, this section is for you. There are a few but solid facts that will prove the advantages of thermal vision devices. 

First, you can use them for different hunting tactics such as bait hunting, 24/7 hunting, or drive hunting. Another plus is a high range detection. Each thermal weapon sight has high recoil resistance properties and is easy to install on any weapon. 

Here are the situations when thermal scopes are the best helpers: 

24/7 coverage 

Apart from visible cameras, thermal scopes are consistent at day and night time. They do not depend on a good lighting environment and can “see” perfectly well in poor contrast conditions.        

Long-range detection 

With the thermal scope, you can easily detect faraway objects. Some devices can catch the temperature of the object at a 50 km distance. 

No obscurants

Thermal radiation can be seen through many natural barriers. 

Poor visibility caused by fog, smoke, or dust is a no stop to most thermal vision devices. A thermal vision sight can detect the object covered with other material like cloth, foliage, or even a wall. When there is no chance to identify the image, it is always possible to “see” its heat. 

Precise sensing 

A thermal weapon sight can detect temperatures from the lowest to the highest. In most cases, the image is reflected in different colors. The white color shows the hottest temperatures. The blue informs that this part of the object has the lowest temperature. 

No illumination required      

A device with the thermal vision for hunting works well without an additional source of light. Complete darkness will hide the hunter but not the prey. 

Thermal vision devices offer versatile solutions in many unfavorable hunting situations. Long distances, no light, a wide range of obscurants are not the problem anymore if you are a happy owner of a thermal vision sight. 

For these reasons, thermal vision sight equipment is getting extremely popular among hunters. 

Types of thermal imaging devices

By design, there are for thermal vision devices:

• Thermal Clip-On System. It is installed on the forearm of the weapon. It features excellent sharpness and is mainly suitable for mid-range night shooting. It has a quick-release mount. Thermal Clip-On System is cheaper than other thermal vision devices. 

• Thermal Weapon Sight is a monocular with a reticle that is easy to install on the firearm. It can identify the size of the target and the distance to it.  The key advantages are shock-profitability, waterproofness, and variable image brightness. 

• Thermal Binoculars. It is a dual-eye viewing system for the convenience of a user. Binoculars allow extended viewing and are simple to use. The device has an ergonomic design and solid resistance to harsh weather conditions.

• Thermal Monocular. It is a compact device applicable for any weather conditions. It is kickback sensitive but has a tracking of hot spots function and high sensitivity detector. All monocular models are outfitted with extra batteries and an additional WiFi module.

These thermal vision tools can complement accessories such as a thermal scanner, scope mounting system, a tripod, an AGM WiFi module, or an AGM recorder. 

When choosing thermal equipment, you need to know your purpose. Clip-on systems are not for constant use. Binocular or monocular thermal devices are better applicable for observation or tracking purposes rather than for shooting. Thermal Weapon Sights are best for hunting.

Here are the features that make a thermal weapon sight stand out: 

  • High-resolution display.
  • It can be used in all climate conditions.
  • It has an additional set of rechargeable batteries.
  • It is lightweight.  
  • It features high kickback stability.    
  • It offers three lens versions (25mm, 50 mm, and 75 mm lens).

Whichever thermal scope you choose will help you identify the hunting object in difficult weather conditions, at long distances, and from diverse positions. So, it is not a surprise that the popularity of thermal vision for hunting is rapidly increasing. 

Tips for choosing the best thermal scope

When you plan to select a thermal weapon sight for hunting, you should learn how thermal scopes work. Here is embracive research on purchasing factors to buy a top-quality thermal scope. 

Identify the Application Area 

Thermal scopes are used for many purposes. So, first of all, you need to determine where and how you will apply it. Once you know the right properties, a thermal scope will serve you best. 

Think About the Size 

It is advisable to consider the size of a thermal device. For example, bigger models have higher resolution. If you are looking for a thermal scope for hunting purposes, everything will depend on your rifle type. Experienced hunters prefer standard models which will fit any uniform firearm. 

Do Not Forget About the Longevity Criterion 

The resilience of both fire weapons and their accessory is a key selection factor. If you skip this crucial factor, there is a risk that your new thermal device may break within a short time. They always come under mechanical stress and wear out due to dust, water, or heat difference. Therefore, you should purchase a thermal scope with a long operating life cycle and other guarantees. 

Find Out How Long the Battery Life is 

You should go for an accumulator for outdoor activities that will last for no less than eight hours. Otherwise, you will fail the hunting process quickly. To prolong the battery life, please do not overcharge it and never save on the battery price. 

Evaluate Magnification Capabilities   

For the right choice, you need to consider two main factors range capability and target size. You can read about the magnification features of the thermal scope in the instruction sheet.

This selection criteria checklist can be followed by specific advice from your hunting service consultant.        

Once all the tips on picking a rifle scope are considered, you can make the right choice and enjoy the hunting process to the full. 


When it comes to purchasing a thermal vision for hunting, you had better consult thermal vision manufacturers. They design thermal cameras and can select a device for every specific purpose. Today, you can choose among cutting-edge thermal vision solutions and cost-effective devices. Besides that, every other day price for this type of hunting equipment is getting lower.
