Once you have your rifle, it’s time to choose a scope. There are a number of scopes that work perfectly well in daylight, but for any night hunting, you will need a thermal rifle scope or something similar. While some may prefer night vision, thermal imaging is becoming clearer all the time and provides a few benefits that night vision simply cannot match.
How Does Thermal Imaging Work
Everything emits some amount of heat. Thermal imaging is able to read those heat signatures and assemble it into a picture for viewing. The technology is also known as infrared imaging, and there are three basic categories of which thermal infrared is the largest spectrum.
The primary difference between thermal and the other two spectrums is that thermal infrared is actually emitted by an object rather than reflected off of it. So the scope is pointed in a direction and can differentiate between subtle temperature changes to form the image.
It can even give you a fair idea of the terrain around the target, too, and doesn’t require ambient light to operate.
Benefits Of A Thermal Rifle Scope
One of the biggest advantages of a thermal scope, and the one that sets it apart from night vision is that it allows you to see through obstacles like thick brush or smoke. Thermal imaging has been used by law enforcement, the military, and security services to spot human activity through fog, smoke, foliage, and dust.
What this means to a night hunter is that game can no longer hide in bushes to evade detection. Thermal scopes are considered particularly beneficial for hunting boar for this very reason. If you’re worried about lag time, or the viewer not translating the image quickly enough, the technology is improving all the time. A quality scope’s lag is undetectable by the human eye.
