A combination of 50% tarsal gland scent and 50% estrus scent THAT IS EXTREMELY STRONG. Will work either wet or dry, and will last all year. Works best JUST before, during, and JUST after the RUT. The purpose of this product is not to draw the deer in, that's the stick's job. The purpose of this product is to keep them around all week while you are at work. Works extremely well on ALL deer species, and has been proven, for some reason, to work exceptionally well on elk.
