"I bought a Wild games Zero Trace (2) years ago now. I hunt a private farm that is highly managed and these deer are lets say not pressured and in my opinion are more skittish than most on human scent. I was getting busted every time I used the Zero Trace, sometimes when I did not have it I would not get busted which I found odd. However, I bought an Ozonics not 3 weeks ago. I went in got set up perfect for a west wind. I was in the pines which I can not hear anything and I had the Ozonics pointed directly west behind me. A 150" Whitetail snuck up on me and ended up under my stand dead downwind. I shot him at 30 yards and the rest is history. I am a manufacturer so anything that actually works and have people that stand behind it are good in my book. Thanks guys and hope to have more success in the future!"
