If you're going to "play the wind" (my understanding is to set up so deer will be upwind or crosswind of your stand), I'm not sure how Ozonics would help. Wouldn't the ozone go with the wind, to where the deer aren't? Just a question and not bashing anyone for using this. I have no experience with them, so will not say it won't help in a downwind situation, which most people try to avoid. I will most likely never own one since I have other hunting stuff to spend money on, and it's probably too pricey to be a gift from family.
