Thermal rifle scopes and weapon sights are by far the coolest optical devices you can install on a weapon. Not only do they offer the flexibility of daytime and night time use, but they also deliver in weather conditions when other optical devices simply fail. Fog is one such example. Like all other thermal imaging devices, thermal riflescopes and weapon sights read off thermal signatures of all objects and present the user with an image showing a gradient map of the heat signatures. Most modern thermal riflescopes feature several color palates as well as the all time standard black and white. Both ATN ThOR or Pulsar Thermion XM50 or affordable AGM Secutor TS25-384 optic lines for sale have the color mode. Another fantastic feature of thermal rifles copes is their ability to output video signal by means of a special portable digital recorder you can now easily record your hunts to show friends and family. When picking thermal rifle scopes and sights, it is important to understand what you should be looking for. Key components of high importance are objective lens diameter, resolution and refresh rate of the thermal core, magnification capabilities, reticle patterns and battery life. Most popular scopes are typically 3x 50 to 75 mm lens thermal vision scopes with 60hz like N-Vision Optics HALO-LR 640x480 Thermal Imaging Rifle Scope Such a device will handle really well for hunting in the range of 300-350 yards and beyond. Another important point to note is the difference between night vision riflescopes and thermal imaging scopes. Night vision optics in general present you with the real picture of what is in front of you by simply making those items more visible than they are to a naked eye. Thermal devices work differently. Due to the fact that thermal scopes read and reproduce on display thermal signature of an object, you cannot expect to see all details of the object you are looking at. You will only see an outline of items which have contrasting temperatures. This makes thermal less practical when dealing with target shooting and when identifying specific features of an animal very important. Probably the most common use for thermal rifle scope is for hunting pigs.
