call it an old scam then, same diffence. It's not needed to kill deer and like I said, the last place I want a deer that I plan to kill is at the base of the tree that I'm in. Just like scent lok, truth serum, and rage broadheads, I've been killing deer without any of them and will continue to do so.
It's a wonder anyone ever killed deer back before all the "stuff' that is marketed these days.
