I use an ozone machine that cost $40 to keep my hunting clothing and gear scent free in a cabinet at home (I think it's called scentpurge or something). It uses a charged ion method to create ozone and over a couple of days it will kill the scent on your gear if you keep it running continually since it has to fill the cabinet with the charged air and give it time to do its job. However the idea of having an ozone generator trying to kill your scent on-the-fly sounds tricky. Ozone doesn't mask but kills bacteria, and other odors. I'm thnking it is killing the scent on YOU while you sit there which would work to some degree. (Not to mention you are not supposed to inhale the ozone as stated on government
health websites)
