I made an ozone generator rather than buy one. I hunt from a tower over bait at night. Other than hearing a sounder I had no way of knowing where a lone boar came from. Pigs are not born with a fear of human odor. It is learned. I have had sounders cross down wind of me and not be bothered! Just my thought but if I can smell ozone why can't they? How long does it take before they link ozone with danger? Ozoning your hunting clothes in cooler weather, maybe! I realized no help before the transformer burned up that I could tell!
The bottom line is that ozone does work, but for it to work, it needs to be in a concentration that is decidedly unhealthy for people and the ozonics machine does not produce such concentrations of ozone and it is not intended to be used where such concentrations would build up.
