Everyone on here will have diaphragms. I have about a zillion of em, but don't use em much. I can use my slate alot better. My dad however, is good with a diaphragm. It's hands-free and easy to carry in and out of the woods.

There's alot of instructional tapes out there on how to use diaphragms...or you can just listen to turkeys and imitate what you hear, on the diaphragm, with your mouth.
