A push button would be the easiest to start out with, but the volume is usually not very loud. If you are hunting on a windy day, even though turkeys hear extremely well, he may not respond to your call. This is where a box call may come in handy. I would try both. They are both easier to use than a slate or mouth call for a beginner. I have tried to teach a couple of guys to use a mouth call and they still can't get it. I would buy a couple of mouth calls though and practice.Mouth calls are just about the only call I use. I have a couple of slate-pot calls I like to mix in too. Just remember, you don't have to have something expensive or fancy to call in a turkey, you just need to know when to call and when not to. That will come with experience. A box or push call will work just fine for you.
