I have walked right past a blind using white light as any night vision I'd had was gone. Have used red filters when predator hunting and it did not spoke the critters. Use green lights for night hunting hogs and I am not sure what is going on but sometimes they completely ignore it and others they spook as soon as the lights come on. I assume the lights make some type of noise I am not hearing. If the walking is difficult or temperatures are warm enough for snakes I like a red or green head lamp backed with a hand held white flash light that I just use briefly to check terrain and for snakes.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
