It takes time buddyI Would suggest watching some turkey hunting video's and getting your hands on some good reading material!!! There are a lot of good reads out there on the subject of spring gobbler hunting...

I learned a lot about turkey hunting from video's... Back in the later 80's and early 90's the video's were a lot less comerciallized... And the hunters were actually hunting, not trying to sell there calls/ground blinds/decoys

So I really don't know how much the DVD's of today will help you... But the reading material is still out there

Good luck
