I don’t use ozonics but I did build an ozone closet and tote for my boots and first outer layer. I am very convinced ozone reduces your scent profile but nothing can eliminate it. It can make smelly boots and clothes not smell. I think people who spent all the money on ozonics convince themselves it works (my friends included). You have to think about what your trying to achieve by using ozonics in a tree. Are you thinking the ozone layer is mixing with your scent molecules and reducing your scent profile or do you think it’s eliminating/destroying scent molecules. I would believe that if the unit was the size of your body, maybe. But to try and say it “showers” ozone over you is not convincing. Wind and thermals do strange things when they mix, most of your scent will get by untouched. Now in a blind, maybe it helps out who really knows. I would say ozone your clothes and play wind and thermals before spending money on that.
