What do you guys know or think of Gamefinders? Where I hunt it is very thick scrub oak, and pygmy pines. I killed two deer this year that were very difficult to find, one went 60 yards after hit, and the other about 80. Its so thick, that you have to cut your trails after you get off the main trail. These deer were not considerate enough to die on the trail. Been thinking about buying one of them electronic GameFinders. Any good, or save my money??
