I for one am guilty of calling too much I think. I have a good set-up most of the time, but have blown my chance onseveral occasions because I was calling to much I think. I've been trying to give it more time between calling sequences to give them a chance to try tofigure out where the call is coming from instead of pin-pointing exactly where its coming from. I don't know if that helps you any, but I've been nailing more dogs since doing it. The best advice I can give you is LISTEN to these veteran coyote hunters, their good, and know what their talking about. Good Hunting .... SHOTARYE
