I've been sucked in by the occassional gadget -- most are gimmicky junk. When you are hunting a color blind animal, pretty much any camo that breaks up your outline a bit will work (and isn't absolutely necessary anyway, but I believe it helps). Scent absorbing clothing? Don't see how it can work given that you are breathing all over everything -- I do use a cover scent though. UV brightener destroying detergent -- please. . . But, every once in a while you find a gadget that works -- I keep a Butt Out tool in my pack, best gimmick ever invented.
