+1 for above advice.
I hunt pretty much all public land, it can be rewarding.
My advice for someone starting out.
1 hike in silently and never let the wind blow your scent over the area you will be calling to. Take the first useable stand, don't wander around looking for the perfect stand. After you finish the stand either a blank or productive then check out better locations at that spot. I don't know how many coyotes I've bumped or stands I've ruined by spending too much time looking for the perfect spot
2.dont try and get fancy alternating sounds, trying sequences. I like quiet sounds vole squeaks, bird sounds and baby rabbits. Leave your caller running and maybe vary the the volume a little.
3. Minimize movement and sound, if you just can't leave the bino in the truck. Scan before you turn on the caller or after you decide to quit the stand. If you can see a coyote in your binos he can see you lift them to your eyes because he is focused on where the sound is coming from and watching for anything that is there. Get set up and comfortable, once you turn on the caller you should be like a statue only slowly scanning with slow movements of your head and eyes. When you start it is hard to not swivel your head around trying to see everything right now. As you scan look for movement or things that weren't there on the last scan. If you see something don't get tunnel vision, keep scanning, keep that spot in your peripheral vision and watch for changes. I did not know how many times I've spotted something out of place well into the stand that just turned out to be a grey stump, and while staring at it have a coyote right in front of me.
A little story about sneaky coyotes. It took two guys out on a oil field road, lots of traffic we parked on a little hill and stepped over the side of the road bern, you could throw a beer can into the bed of the truck from the stand. There was the corner of the bare pasture that came up to the road and a spring a couple hundred yards out in the pasture the corner of the pasture that we were sitting about 10ft over was full of brush with brush running out along both fence lines. About five minutes into the stand the was a.coyote sitting about 20 ft away looking at the decoy clipped to the fence post. Both guys were scanning the pasture and I had to nudge the guy closest to me and point down and he had the calm to kill it. A.couple more minutes and there is one sitting on the other side 20 ft away and I had to point it out, it died but still the guys thought it was anomaly and we're sure they were going to see one out in the pasture when #3 comes in and sniffs dead #1 he made a get away before they could focus on him. So now they are watching the fence lines close.in and coyote #4 walks across the pasture about 100 yards out where they had been focused when the first three came in under their noses... I had to whisper, "he's out there" both were good shooters and doubled on him. Never count on coyotes to do the right thing
Have fun and good luck.
A public land hint, look for places no coyote hunter would hunt. I've had a lot of places that look unhuntable but a pair of waders will get you to spots that even educated coyotes will come into unafraid because they've always been safe there. Or like the little corner above, right next to the road. Ive posted pics of coyotes kill just far enough from the interstate to be legal. Here we have a lot of tight four strands barbwire that you can't crawl through or under. I carry T-post steps and a piece of carpet to toss over the top wire and hunt un-hunted land right along the road..
