Nose Jammer jams big game animals’ ability to detect and track human odor. Utilizing fresh, natural aromatic compounds from vanilla, Nose Jammer unisex, aerosol field spray creates a cloud of protection around the hunter preventing human detection by Game Animal’s sensitive olfactory system. When the wind swirls, critters olfactory gets jammed and they stay calm and unalarmed. To use while tree stand hunting, spray the bottom of your boots up to your waist before you head into your hunting area. Once in stand, liberally spray the tree and limbs from below your feet to above your head. While Spot and Stalk hunting, spray clothes, pants, and boots heavily. The goal is to create the Nose Jammer cloud that surrounds the hunter. One application lasts about half a day. Re-apply halfway through on extended hunts. Nose Jammer is most effective when the complete line of Nose Jammer products are used for hunting. Works on all critters with a nose!
