I hunt mainly from the ground, so scent is a major issue. I bought the dander and sprayed it on my boots and clothes. deer never noticed me the first three nights i sat. Then i tried the real test. I set up, up wind of a major deer trail. I had deer stand 20 yards directly down wind from me and not freak out. They sat their for about an hour eating grass etc... Sitting on the ground upwind, i think it works.
