Nose Jammer is NOT a cover scent and it's NOT an attractant, it is an olfactory nerve overload system. Nose Jammer contains Vanillin and other organic compounds that effectively jam, or overload, a big game animal's sense of smell. Best of all, it does so without alarming the animal to danger because the Nose Jammer formula is made with naturally occurring compounds commonly found in North American woods. The key is taking these natural compounds and delivering them at concentrated levels. Just like an overly bright light can wash out a photographic image, Nose Jammer overwhelms the olfactory system, overpowering an animal's ability to detect and track human scent.
