"I hunted last year with a man who used the Ozonics. I questioned how it worked but did my research. I decided to buy the Orion unit over the summer of 2020. LONG STORY SHORT, I hunted over 50 times during the 2020 season and NEVER NOT ONCE was smelled by a deer. Not once did I hear a snort and see the white flag. I also believe in cleaning my cloths as well which ads to the effect. I had multiple opportunities at bucks in the 2020 season but was able to harvest a great 9 point and a 12 point. I love my Ozonics and will not go into my stand without it. Save up do what ever you can but if you are a whitetail junkie like me it CAN ONLY HELP YOU HARVEST A GREAT BUCK."
