I tried deer dander last year, and i can say for sure that it does not hurt any. I also think it may have given me a shot that might not have presented itself if I had not used it. A doe that was following a trail that would have taken her directly under my stand crossed a stream and gave me a broadside shot at 20 yards right next to a tree I sprayed some deer dander on... I also had the stuff on my boots and felt she may have followed that trail to the tree. Did she? I don't know for sure, but like i said, it certainly didn't hurt anything and may have helped cover up my scent. I have some friends who swear that the stuff has saved their hunt. One friend in his first year hunting wore some clothes that were not exactly scent free... his brother doused him in deer dander and he shot a beautiful buck... I have a few posts under my name, and I'm not pushing this product in any way, just relaying some experiences with it.
