LockDown Corn uses an easy but effective scent delivery system. To use, simply remove cap and apply pressure onto a surface to activate the sponge applicator. Next, wipe the sponge on trees, rocks, stands, or anything else in your hunting area. After application, hang the bottle in your hunting area with the attached cord. The sponge will constantly wick scent into the air. After use, wipe the sponge clean and replace cap. Made with all natural products and bottled in the USA. LockDown Corn scent is an amazing lure for deer and one of our top sellers!
