BUCKCAGE is on the cutting edge of technology. Use any scent of your choice... no wick, no reservoir, reusable, no mess. Simply add 1/2 oz of your favorite urine or coverup scent, drop in the BUCKCAGE and wait 30 minutes. Hang your BUCKCAGE on a tree limb over a scrape beside your stand for a great coverup, or along the trail to lure him in.
