I have coyote hunted the Black Hills, and surrounding prairies, 3 times. Not one coyote has even come in. I have a Flextone, handheld trigger style e-caller which I do not think is loud enough. I pay attention to wind Lthough because of my caller I let the wind go from me to the coyote so it will carry the sound. Bad idea? I camo up all the way and try to sit on tree lines overlooking fields so I have cover. I have tried raccoon calls, fox calls, rabbit calls Nd coyote barks. Nothing is working. I sit a out 15 minutes and call for about 3-4 minutes. Then I don't call for a mi ute or so. Any advice would be appreciated.
