All, last fall I seen a show on that talked all about going to and from your stand in the dark. On of the main topics was using colored led head lamps and they did a study of which one was the least disturbing to the deer. They actually showed the hunters walkingwithin twenty yards of the deer with one particular color, were as the oher ones did make the deer a little more nervious or spoked. Since then I have forgoton the one that was the best and the show has not been on since. I think the colors they showed were red, blue and green, and I think red was the best but not sure? Any one else use colored leds with sucess? Thanks!
