If I spook a deer that HAS NOT seen me, but has spooked due to sound or something of the sort (like while walking into a stand) I will snort BACK to the alerted deer. Deer will snort sometimes as a communication tool. If you snort back, they typically settle back down and think it was just another deer that spooked them.
I played this game with a doe last year for about fifteen minutes while trying to walk out of a stand in the dark.. She'd snort, run away, I'd snort back, and she'd walk right back to me... Then she'd spook again, I'd snort, she'd come back.. All I was trying to do was settle her down --not call her back.. But everytime I'd snort back she'd walk right back to me.. I ended up saying screw it and walked out after she walked away the third or fourth time.. But I would definitely say that the snorting back calmed her enough to approach me atleast three times...
Dont think this is just some remedy I conjured up either lol.. I actually heard this tip somewhere before, so I tried it, and it's worked for me a few times..
