A while back I bought a set of 3 Primos calls. It came with a cd that was pretty informative on how to use...also you can go to youtube and find pretty good tutorials. The best way to learn, though, is to talk to someone that knows what they are doing about it. Not on a forum, but in person. Will help a good deal. If you don't have someone to help you with it, then maybe try the cd route, or youtube.
