I don't know what the right answer is. I use the scent free soaps, deodarant, sprays, X static socks and underwear, but stop short of using the Scent Lok or other carbon suits. I have deer come right up to me, just under my stand without spooking. With that said, I almost got run over by two deer scouting for spring turkey season, no scent control measure and chewing a wad of Redman. I had to say something to keep them from coming right over me!
