My problem is the wind up here decides to change right after I strap me & the climber to the tree. I hate moving especially in the pre-dawn twilight.
That happens here at fort gordon too. I've had good luck with using spray and washing my hunting clothes with scent free detergent. I always try to play the wind but that is hard to do the first half of the season. I do think the the Ozonics is overpriced and probably unnecessary.
