I am a firmer believer in Ozone killing scent. My routine before a hunt is to throw my gear and clothes into my jeep and run it for at least an hour, longer if I can. I will shower if going out for an afternoon hunt, but not a morning hunt, because I do not want to wake the wife and kids that early. That works well enough for me, and the times I have been busted has gone down drastically since I started doing this. Having hunted with @LittleChief a few times, I trust his opinion if he says it works. But, I am not in a position where I want to drop the money on an Ozonics unit.
