Bloodhoundhandler - I understand how you feel about mature bucks. I've been winded by many over the years. I have had a dozen or more bucks between 4-1/2 and 7-1/2 (give or take, tough to tell) straight downwind while using Ozonic's (with a cameraman in the tree). The reaction of a big mature whitetail is always unique to that animal. They are just a different bird as you know. The reaction ranges from absolutely no reaction at all (not even lifting their nose), to a weirded out reaction, to a cautious curiousity. Regardless, when they are weirded out by this "new smell", considering it's likely the first time they've encountered it in their lives, the effects are NOTHING like when a big mature buck catches human scent. Believe me I know when I've been winded. There is no hiding the muscular contraction that goes through a whitetails body when you've just been had.
With that being said, even if a mature buck will get slightly weirded out here and there, I'll take that over the alternative. The difference is night and day. They don't "hit the ground and fly" out of the area. It's almost like a "I don't like it, but it's not dangerous" type of a reaction. Some mature bucks, especially during the rut, could not care less. They actually get straight down-wind, lift their nose, and come straight into the stand to investigate WTF that smell or sensation is that they "feel/smell".
In-case you care (which I don't think you do), we have this documented on video time and time again over the past 3 years. I have 4-1/2, 5-1/2, and 6-1/2 year old deer reactions on our latest video "The Dark Side". Some of these reactions are also on our web show. Explain how we can fake a buck sniffing the wind and coming straight to our stand while looking up at us. This is NOT something 5-1/2 year old bucks do when they catch human scent. This is ALL on video, and the hunters name is Dallas Ft. Worth. The best Ozonic's promotion in the world when we can clearly show mature deer reacting to our scent by coming closer to investigate the strange new smell.
The HUGE factor that i consider to be the no-brainer for using Ozonic's is that when does get down wind, they DO NOT SNORT. They can be looking up at two of us in a bare-naked tree, straight down wind, walking circles around the stand for 30 minutes, and they won't blow. Tell me that doesn't change things. I can't freaking tell you how many hunts I typically had blown out because of these darned does. In 2010 we didn't get snorted at by a doe because we got winded once in 60 days of hunting. You can think what you want, but Ozonic's can and does beat their noses every freaking day we're in the field!
