Yeah Thermal would be awesome! However it might not be great for Non-living targets... after all most of our targets are the same temp as the surroundings. However Predator Vision is pretty cool!
Hand warmers. Cheap targets for sighting in a thermal unit.
In 5-10 years they will be down to a few hundred bucks...
No. They won't. Actually, price has gone up (albeit just a little, but it's still the opposite of down) the last couple years. That said, a good thermal unit doesn't cost 10 grand. The ATN Thor 320 and Armasight Zeus with 336 core can be had in the 5-6 grand range, and they're great.
