One of my friends on Canada is planning to do some Wolf/Coyote hunting, he has a real good place to start, but he asked me if I can help him? He would like a calling device that he can remotly use, having the device 300 yards out from where he is shooting. Also a remotly operated control to turn on a flopping decoy. the place he will be shooting has two land masses east/west and he has a large outcroping of boulders sticking out of a lake, he will have his back to the rocks. I have no idea where to start, I just kill woodchucks.
