A Guide To Selecting Thermal Scopes

Thermal scopes are the absolute best as they aren’t influenced by light, dust, or even fog. Since these devices use heat to create the image of what you’re trying to see, they are very convenient to use. However, buying thermal scopes is a complicated task.

Before you go shopping for thermal scopes, you need to consider a lot of things. Don’t worry; we are here to help you out. Below, we have made a guide to selecting thermal scopes. 

Types of thermal scopes 

Thermal scopes and weapon sights come in different types to fit different purposes. Below are the two major  types of thermal scopes you can buy:

  • Clip-on thermal scopes: These thermal scopes work quite efficiently as you just need to clip them on. However, once you zero in on them, you can’t go back. With these scopes, all you need to do is clip them on, and your normal scope becomes a thermal one.
  • Stand-alone thermal scopes: These scopes are mounted onto the rail. They also come with an inner reticle. Further, you can adjust the elevation and windage of the inner reticle. As a result, you’ll be allowed to zero in on the rifle.

Price consideration

Price also plays a very important role while you’re buying a thermal scope. The lowest range of thermal scopes can be up to $1000. While the expensive ones can be around $20,000. Thus, you should consider the price with all of the features offered to see whether it’s reasonable or not. 

Ruggedized or Not

Since you are investing in thermal scopes, you should go for the best ones and optimize their use. So, you shouldn’t go for commercial thermal scopes as they are often sold at a lower price with a shorter lifespan. On the other hand, many vendors provide military-grade scopes which are ruggedized. 

Moreover, commercial scopes often cause problems in shock or impact-resistant ability and focusing on an area after continuous shooting. Thus, it is recommended that you go for military-grade thermal scopes as they remain effective in the long run. 

The reticule option

The reticule or reticle option allows you to get a clearer sight of the target. Many vendors do not offer reticule in the array of thermal scopes. Thus, you should always ask the vendor whether they provide reticule or not.

When you are going for military thermal scopes, it is essential that you go for an inner reticle. Also, make sure the vendor you’re buying from isn’t providing you a crosshair without the ability to adjust the wind age and elevation. Thus, it is recommended you buy from certified places like www.agmglobalvision.com.


Sensitivity is also referred to as the NETD in thermal scopes. The sensitivity of thermal scopes refers to the ability of the scope to pick up even the slightest change in the temperate of the object. 

The lower the sensitivity of a thermal scope, the more effective it will be. If you are buying thermal scopes for military or industrial reasons, then you should be very careful of the sensitivity of the scope you are buying. Also, if you are buying for the aforementioned reason, you will require a scope with  40mk or less sensitivity.

Resolution and refresh rate

Resolution plays a very significant role in the effectiveness of the scope. Thus, it is crucial that you pay attention to while choosing the resolution for your scope. Many people believe the resolution of a thermal scope to be the resolution of the image.

However, it isn’t so. When thermal vendors talk of the resolution, they refer to the resolution of the detector and not the overall image. While deciding on a refresh rate, go for a higher refresh rate as it provides better and smoother images.
