We have taken a look at the best thermal vision optics on the market and put together this buying guide and reviews page. One of the most important tools to have when you are out hunting is a good quality pair of optics. Thermal OpticsThermal rifle scopes and optics are one of the coolest inventions and game changers for hunting. They are different from traditional night vision optics because you are not limited to using them at night, and you don’t have to be stuck with that green grainy view. Thermal optics give you the flexibility to use these scopes and optics during day or night. Thermal vision can also deliver crisp images in bad weather, where other vision technologies fail. I prefer to look through these instead of the regular night vision because it highlights the heat sources to show you the animal that you are seeking. It’s just a neat technology all the way around. The prices are getting cheaper as advancements are made in the technology and manufacturing process, which is a win win for us!Fog is an excellent example of where a traditional night vision scope would fail. Thermal rifle scopes and other optics read off thermal signatures of all objects and present you with an image showing a gradient map of the heat signatures. Even in Fog, and through grasses and other brush! Most modern thermal optics feature different color palates as well as the standard black and white. Some of the higher end optics can output a video signal by means of a special portable digital recorder so that you can easily record your hunts to show your friends, family, or online community. Some of the key components to look for when you are looking for a new thermal hunting optics are objective lens diameter, resolution and refresh rate of the thermal core, magnification capabilities, reticle patterns and battery life, and whether they are waterproof.
