Game Finder Junior The exclusive "Selective-Sensing" is included that virtually eliminates false readings. Virtually eliminates all porous things like bark and leaves, and dense things like hot rocks and metal. It selects things like people and animals.

It's highly effective for recovering big game and fits in your shirt pocket for easy portability. Simple-to-use; just turn it on and scan. Operates on one 9-volt battery (not included).
