One of my bowhunters has a little black box ozone-ater thingy he screw into the tree he sits in. The fugging thing cost $400 bucks, and everyone that's used the tree before him, without the magic snake-oil box, seemed to score anyway.....He gets pissed when I laugh at him.
Ozone Generators work. Now wait a minute and hear me out!
They are used commercially all the time.
However they do not work in the hunting world!
Yes, yes, yes you can kill the odor on your clothes with one. However as soon as it is removed and worn you create more odor.
Yes those Tree mounted boxes mask small, KEY WORD HERE SMALL amounts of odor. Not small enough to fool an animal.
Last your skin is constantly exfoliating! Tiny tiny microscopic pieces that animals can and do smell.
