besides your weapon of choice of course....lol I seldom buy gadgets or magic potions.. But Last year I bought some of Dan Fitzgerald's deer dander and I have to say the stuff works great.. I guess it is similar to deer herd in a stick as it smells like deer and is not a rut scent.. It seems to work great year round as well.. I often spray it near my camera sites and start getting pics almost immediately. I spray it on my boots as I walk to the stand and have had deer track me to the tree. I put it in my tinks scent bombs as well... So I would say it is the one thing I use every time I go in the deer woods.. The one thing I do hate about it is the spray bottles suck and will get all over your hands when you use it..
