I have a buddy that lives in Idaho, not sure of the exact location, but near the middle of the state. He bought a cs24 a couple of years ago on my recommendation. He has never had any success. I have the same caller and live in n.e. n.carolia and have had good success with the call. I have been to n.e. montana once, and called in two on three sets. I have told him everything that I know to do. He talks like there is wide open space, with rolling hills there, elk, mule deer, wolf and cougars also around. Does this type of terrain require a different set up? Any help would be appreciated, he is getting discouraged, and I feel bad for talking the cs24 up. He had an alpha dog that he had bought, and I told him to get the cs24 and never look back. He has killed several coyotes deer hunting in the area,
