As for calls, I blown so much money on the latest and greatest. A cheap owl call works great. A slate and wooden striker is good. ( make sure you have steel wool or pad to keep it clean during the day). Slate calls will give you the volume and reach when needed on windy days. I like a raspy mouth call. This is my call of choice. I practice when I drive, so I don't drive the rest of the house crazy. That is it.

For a beginner, a push/pull box call is the easiest and works great. A slide box call, which is popular, can be a lot tougher to learn and control.
