Nose Jammer Scent Elimination Field Spray helps hunters stay un-detected in the field, creating a cloud that surrounds the user and jams big game's ability to detect and track human odor. Nose Jammer should be sprayed on clothes, boots, tree stands, blinds, and brush. Then when the wind swirls, the game's sense of smell gets jammed and they stay unalarmed. Works on all critters with a nose! Use Nose Jammer Field Spray in conjunction with the rest of the line of Nose Jammer products for best results (not included). Size: 4-oz. Aerosol can.
