I had aquired some factory second ASAT last year and tried it out during the late archery seaon here. I was sitting on a stool behind a small fallen cedar, smelling of Deer Dander. I was facing west since it was morning and there was a large bedding area behind me where the returning deer would go after feeding on a nearby ridge. I heard something walking through the leaves behind me, which pretty much had to be a deer, so I waited for the inevitable blow and sprint since the wind was blowing in the deer's favor. To my astonishment the deer approached literally close enough for me to hear it sniff me, it didn't sound alarmed in the least.I figured that the Deer Dander had gotten it's curiosity aroused, and it had walked the 30 yards from the bedding area to see who "the new deer" was. I'm fairly certain that it could see something, it just didn't perceive me to be threatening until I turned to look at it. Once my head turned that young buck snorted and covered that 90' in amazingly short order,and even then it paused at the edge of the cedars to stare in my direction before bolting. LOL
