Yes - been busted many times, years ago. Thats why I try never to make eye contact with a deer when its staring directly at me within 30-40 yrds. I will hunker down in stand or hide behind tree. I kill deer every year using this tactic. No EYE contact. If no eye contact you won't blink.
I rarely stand up in a stand but when confronted by deer while standing,I will stand stone cold still and look down so as not to make that eye contact.
I firmly believe predators often cause prey to flee simply by direct eye contact. Man is seen as a predator. The eyes of a predator put fear into its prey.
Might sound crazy but I'm stickin to my story
