Good advice from Lonny.
Picking your stand is crucial for success. If you set up with a brushy creek bottom 100yds downwind of your stand, you will never see a coyote.
If there is one thing I can etch into concrete, it's that coyotes will always, always, try to get downwind of the call.
As soon as you let the first sound go, any coyote in hearing range knows exactly where your stand is, probably to the nearest 20-30yds.
I use handcalls, and I call for about 20 seconds, then remain quiet for 3-5 minutes. I'll repeat until I'm done with that stand.
I have hunted with guys that turn on the Ecall and let it run the entire 20 minutes on stand, and we did well.
Good luck!
