Best Thermal Sight/Scope for Rifles/Shotguns

Rifles are great weapons for hunting or when you’re performing any kind of long range shooting activity. But if you want to increase your chances of hitting a target, then you should definitely invest in a sight scope accessory as an add-on for your rifle. A sight scope is generally installed on the top of your rifle and it allows you to see far away targets at a closer range. These scopes generally include a crosshair as well so you can easily align your target in the middle of the crosshair and then shoot the target with an almost guaranteed chance of hitting it successfully. If you are a sniper or long distance shooter of any kind, you will certainly want to invest in a sight scope.

However, not all sight scopes are the same because they have different features to them. The thermal sight scope, for example, is a particularly handy scope for allowing you to see targets in dark or nighttime environments. Most people would use tactical flashlights to see their prey at nighttime but the problem with that is their prey will notice the light and then run away. A thermal sight scope, on the other hand, does not emit any kind of light towards the direction of the prey. Instead, it gives the shooter a thermal signature of all the warm-blooded living organisms in front of them. Their heat signatures will appear on a gradient map that is displayed on the shooter’s screen. If you’ve ever seen the 1987 movie “Predator” starring Arnold Schwarzenegger, then you probably remember the scenes which show the Predator seeing people’s heat signatures. That’s basically the same kind of imagery you’ll have with a thermal sight scope.

The only downside to thermal sight scopes would probably be their prices. You should expect to pay at least a few thousand dollars for a decent sight scope that does what it is supposed to do. But if you are a die-hard shooter that truly wants to have the best accuracy possible in all types of environments with their rifle, then an investment into a thermal sight scope won’t seem like such a big deal. The three most recommended thermal sight scopes are the Armasight Apollo-Pro LR 640 100MM Clip-On, ATN Thor HD 384 1.25-5X Thermal Rifle Scope, and the FLIR Systems RS64 1.1-9X Thermal Night Vision Riflescope.

The Armasight Apollo-Pro LR 640 100MM Clip-On is a thermal scope for your rifle that can be used in both daytime and nighttime environments. The reason it works in both environments is because it tracks the heat signatures of your living targets no matter how bright or how dark it is in your environment. This type of thermal scope would be perfect for a professional hunter or law enforcement sniper who needs to depend on having good visual capabilities in their rifle scope. That way, they can serve their intended purpose by not missing their target.

The Apollo Pro is designed to meet the 20/50 gold standard of the Armasight company. This is a standard for the scope’s ability to withstand being immersed and enduring the shock and recoil of a rifle after it’s been fired. The Apollo Pro has been tested and proven to endure 20 meters of immersion for a period of two hours. Not only that, the scope can withstand the recoil and shock power of a 0.50 BMG firearm. Chances are you won’t be using a rifle quite this powerful with your scope so you can feel confident that it will be just fine.

The Apollo Pro was designed with common core electronics, a large eyepiece, and signal processing that provides complete accuracy with the thermal imaging technology that it is equipped with. There are two versions of the scope you can choose from; commercial and military. The two scopes are pretty much the same except that one has 30 Hz and the other has 60 Hz. The Apollo Pro can be mounted right on the top of your rifle in front of the magnification day sight without having to remove it. Since it uses thermal imaging, the magnification will only pertain to the heat signatures and not the lighting in your environment. That’s why you don’t have to change scopes in order to accommodate what time of day it is. Best of all, the scope comes with Bluetooth wireless technology so that it can directly be engaged on smartphones that are close to it.

The price of an Apollo Pro LR 640 100MM at 30Hz is $8,995.00. If you want the 60Hz version, the price is $1,000 more at $9,995.00. At these kinds prices, you can understand why they’re meant for commercial or military use. These are not meant for someone who occasionally uses their rifle for recreational purposes. To get the most for your money, you need to use the scope every day as a professional hunter or soldier who endures frequent combat situations.
