I've been using Pete Rickards Indian Buck Lure for 23 years. It always works for me. I do not try to attract bucks with it, I use it to stop them for a good shot. The does do not like it. I put a film cannister with cotton (scent bomb) near the trails that I'm hunting. I place it so that when a buck comes along the, trail the wind will cause him to stop and turn his head away from me. This gives me a good shot opportunity.
Good luck.
