I’m seeing how the information here could seem conflicting to you.
First things first. The best calling in the world will never call a bird can’t hear you. You need to find the birds. Find as many as you can cause if they move they aren’t going far.
Start with a box call. Basic yelps, clucks would be relatively easy. You just need to learn cadence. A pot call has so many variations and season isn’t real far off. It’d be tough to pull off the dexterity needed in that short of time. Dr Lovett Williams has basic CDs that’ll give you something to listen to and imitate. They’re real turkey sounds. That’s the name as well. Real Turkey.
If it rains a bread bag over your box call will keep it dry. You can run it in that bag. David Halloran has some good videos you can you tube. Box call mistakes is one you should watch.
Turkey hunting can be fairly complex or basic. Start w basic. Get between them and where they’re going.
Once they’re committed to you, stop calling. Let em come.
Something you need to know. Turkey loads often do not shoot straight through turkey chokes. Check your gun w turkey loads and add sights if needed.
Mike Staten made you a good offer.
