Have been thermal hog and coyote hunting since 2010. Learned the hard way on thermals which can be a tough learning curve. Just got a Trijicon IR Hunter Mk 2 60mm and am truly amazed at the clarity. This beats my old Armasight and Flir 640 units all day long. Have been on Predator Masters for a long time but they are pushing the Chinese thermals xo I drifted over here.
