The Sitka blacktails, muleys, Whitetails and Coues I’ve seen pretty much come straight in to rattling and calling. They do not circle and scent check like elk sometimes do.
I’ve only used a decoy for deer sparingly…and same thing…they either ignore it..or come straight in.
Decoys, all the big bucks I’ve killed over decoys or not killed have swung wide. It’s gotten to the point when setting a decoy I want to be straight downwind of it, and if possible, have brush something behind me to keep them from swinging too far down wind and picking me. Young bucks don’t care. I’m they come.
In Ohio however, I have had zero luck. My decoy freaks every doe out that comes across it (posted as buck). I've only had 1 buck, a nice 8-point, that has encountered it, he saw it coming out of the woods into a little food plot, stopped at 20 yards, started posturing and pawing the ground and then took the hell off like a bat out of hell. I was so distraught over that, I haven't used the decoy since.
Yes, I sprayed the decoy with anti-scent stuff and yes it was upwind of me. I'm not sure if I just have a bad decoy or bad decoy juju.
