I think a slate is the easiest. Primos makes an instruction tape for all their calls. I've learned alot from the turkeys themselves. I was serenaded by turkeys all this deer season. They were putting and kackling, kee-keeing and even gobbling. It was most awsome. I can hear turkeys now when I used to never hear them while deer hunting. Any time an owl hoots I listen for that gobble !!! IT'S BETTER THAN DRUGS !!!!
