You are going to have a bunch of people tell you "wind, wind, wind". Learn the wind, play the wind, be the wind, you won't kill coyotes if you yourself don't create the magic aura of the wind. I agree to an extent and if I hunted in prairie land or wide open spaces, I would agree more. The area of SC I'm in...the only place you can set up and see 500 yards is down the interstate. If a coyote circles downwind a couple hundred yards out, you probably won't even know unless you get barked at. Yes you can set up in a field where YOU can SEE that far, but a coyote is NOT likely to break from cover and come all the way out into that field. Even coyotes that aren't pressured are still coyotes.
Typical set ups that produce for me is farmland or fields with very thick cover adjacent to it and/or a hardwood branch running next to part of the field. That is where the coyotes will be. You can hunt the field with a rifle or get in the woods with a shotgun, most of it in this area is so thick it's only shotgun distance anyway. In the field, try and figure out corner pocket setups. If you set the call out in the middle of the field, they may hang up just inside the cover or they may just poke their head out to look. They may pop out at the edge for a second and none of those instances make for a good shot.
Getting in that corner pocket allows the call to be close enough to them to entice them out, being closer to them like that lets them still feel safe in the cover and not have to break so far from it to get to the call. They are more likely to run 10-20 yards out to a call than 75-100. Your shots will be quick, but you'll get shots.
In terms of wind, other than not blowing directly into the thick cover or hardwood branch I don't get too wrapped up about it. You are already setting up close to them (be quiet as possible), they don't have much distance to cover getting to the call in which to circle. If they do circle it's within 10 feet of the call or so and honestly 4 out of 5 that I see don't care about the wind. At night it is even more so and because of setting up like that, most of them come straight to the call from upwind. Some of the "experts" will say that is false, but they are likely hunting the Midwest or areas with heavy calling pressure.
If you hunt that spot from the woods, do the same thing...approach it so the wind doesn't blow you out, quietly get as close as possible and be ready for a quick shot. Say you have a 300 acre block and 200 acres of it is clearcut. Hunt the clear cut part even though the other 100 acres might be pretty and give you a good view. Even if its thick like, 40 yard visibility, it's easier for you to hide and when they do pop out they are already in killing distance. They have to break from the clear cut cover just a bit or get close to the call to see it, then bang you got him. Hunt the downwind corner of the clear cut..sit 30-40 yards from it and put the call between you and the clearcut. As long as the wind isn't blowing into the clearcut you are good. Hold on tight and be ready for a quick shot.
You will have a lot of dry stands, but when it happens it happens FAST. When I take people I drill into their head to be ready for 3 seconds of fame, to detect, ID and kill. Anything more than that is a gift. I personally don't see the excitement of shooting them 100s of yard away, when you kill them close enough to see their eyeballs it is the absolute biggest rush you'll ever have. Those set ups work great for bobcats also, but that is a different season and you can't use electronic calls for them here.
