What state are you located in? Your best bet is to get out and do some scouting the areas your going to be hunting. Look for tracks, scat (or droppings) go out with a howler near evening and try to get a few yotes to howl back at you. Or if your not real familar with using a howler, get yourself a tape of a siren and play that. Coyote readily repley to a siren. After you find where the yote are, it's all up to you on how you want to hunt them. Mouth calls, or E-callers. Just remember with a E-caller you don't need a lot volume. Hey good luck hunting....and be safe
