Is thsi another gimmick? Who knows? But how many times have you had a deer coming in - then for no reason you can think of, it stopped, looked around, and did a 180 and walked away?
Maybe there is something behind it but I would not spend any money on one of these suits. Why? Because there is no proven field use of its effectiveness and secondly because at my age, my batteries are so low that I don't emit enough electrical energy for the game to pick up...
