I don' t look directly at them if I plan on trying to get a shot, heck I try not to think about them if their a mature dear. If it' s not a shooter, I look at them, I' ll even wink at them to get a reaction. A wink usually is good for a foot stomp or a head movement and sometimes they will jump a couple of feet. One guy told me I was scaring the deer. I look at it this way, they encountered something different, they were suspicious but it didn' t hurt them or try to hurt them. Maybe next time they will be a little more relaxed.
