The most effective overall Buck Lure a hunter can use. #307 is a complex blend of natural ingredients developed through years of extensive testing in the field, on wild whitetail deer. It contains a unique blending of natural doe in heat urine and special, highly effective hunger & curiosity ingredients that are not well known, but are highly effective. This powerful attractant really brings in the deer by appealing to the sex, curiosity and hunger drives. Highly effective during early season and extremely effective during pre-rut and the rut.
