Deer hunting is just like golf ... every guy thinks that new equipment will improve their game.
I like the concept of the ozone bag, may look into it. I have had great success with Rubbermaid tubes, and putting white & red cedar branches in. Wash the hunting clothes in no scent detergent. I have a no scent bag for in the back of my Kawi Mule to throw cloths in and put on when I start my trail to the stand.
I have some scent lok, scent XYZ, etc. clothing also.
I keep cedar/earth scent disks in my bow case, and all of my equipment is in a tube with cedar limbs also.
I also shower & brush my teeth every time time before I go out to hunt a stand. I have separate towels, underwear, socks, etc. that are washed in Tide Cheer just for hunting.
When I come in, I will hang my cloths outside to air them out before putting them in the tube.
If you feel that ozonics is the answer, then I am sure they will accept your money. I am just not sure how it will make that much of a difference over the above? The human body will give off sent eventually and you cannot eliminate that.
I think a A big area of focus is ... sound/movement & the wind.
I think many people burn out stands by using them too often, checking their cameras out there too often, bumping deer on their out, and hunting them in bad winds.
Regarding sound/movement, a deer's ears are amazing sound receptors. Any sound or movement on the way to the stand, getting into the stand, sitting in the stand can bounce a deer. Mature bucks often stage in transitional cover and will watch/listen to an area before entering.
I have 2 buddies who are amazing hunters. Between the 2 of them they probably have 5-6 bucks each in the 150" to 185" range and 1/2 have been with the bow. Yes they use scent control clothing, store their stuff in tubs with tree branches; however, what they won't do is hunt a stand in an area they have scouted a good buck in with the wrong wind.
Learn to hunt the wind and you will be amazed at how well your scent free cloths/ozonics work
