I have a never used Game Finder Pro 2000 Game Finder. This is a handheld, very light tool that uses differences in heat to find downed big game. Simple to use, comes with a very detailed instructional video and a camoflagued belt pouch. I bought it after losing a big whitetail while bowhunting, but have since quit bowhunting (elbow). Anyway, these things are pretty expensive-- think I paid about $165 for it 2 years ago. Will sell it for $100 shipped anywhere in the USA. This is manufactured in the USA, by the way. Game Finder is based in Huntsville, AL.
