I tell beginning hunters just to master the basics first,...yelps and clucks,...and worry about the rest of the calls later. There are plenty of places to hear basic yelping and clucking,...audio tapes, videos, and TV shows. A hunter that knows what basic turkey yelping sounds like,...and more importantly, knows when to use it, is going to kill more turkeys than the guy who knows all the calls but has no clue as to when to use them. Of course, as you gain more experience in turkey hunting and calling, it is certainly advantageous to learn and master more calls. For the beginner, however,.... just keep it simple.
