I had a young deer spot me this weekend when I went to draw on another deer. I froze and the deer lost me. It was about ten yards away and started looking around trying to find what it was that moved. It could not pin-point were I was even after it saw me move. All the deer did was calmly walk away. I was wearing a 3D leaf pattern. It is one of the mesh kind you put over your other clothes. The ASAT does look like it would work great but I think what I have is pretty good after that experience.
