Trail?s End #307 is a complex blend of natural ingredients developed through years of extensive testing in the field, on wild whitetail deer. It is truly an outstanding buck lure, packed with natural deer calling ingredients, some of which are not well known, but are highly effective. This powerful attractant really brings in bucks during all parts of the season, but especially during the rut. Highly effective during early season and extremely effective during pre-rut and the rut.
