I have a real hard time buying into the sales pitch that the Hecs suit blocks your bodies electrical signals with carbon fibers, or that deer can pick them up to begin with. Hunters will buy anything if they think it gives them an advantage over whatever they are hunting. First it was scent free clothes using carbon , now carbon to block the electrical signals that hunters are sending out. I put it right up there with big foot and the Moth Man and Leprechauns.
