Ozonics Blocks the scent-zone with scent-destroying Ozone between hunter and prey.
Direct from Ozonics: "Ozonics produces ozone by introducing electricity to oxygen much like what happens with a lightning strike - only on a smaller scale. In the presence of electricity, oxygen molecules (O2) will fracture and temporarily turn into ozone molecules (O3) which are characteristically unstable. This means they will bond with other available molecules, like human scent. This strong tendency to bond with other molecules is what results in purification in general and scent control for the hunter."
