LockDown Buck Urine 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. LockDown Buck Urine contains 100% US farm raised buck urine and is bottled in the USA. This is an incredibly powerful lure!
