The first lure of it's kind. Unfair Advantage does not work off of odor, but sight appeal. It glows in the dark up to 12 hours each night, causing curiosity and intrigue from several feet to as far as the animal can see. The daylight charges the lure each day. This lure is killer on bobcats, coon, fox and beaver. Just smear a little on a tree, stick, grass clump or flag at or around your set. I call it Unfair Advantage, because that is what it is.
