Know the woods your hunting.. Have established routes to get in unseen early and be dynamic.
Listen to the birds and how they react and where they go. Turkey hunting has 2 winners, guys who get lucky with hot birds and guys who know how to turkey hunt...

The key to every bird I've shot is that I scout often, I know the land, and I know where the birds are going. I take a weapon, 2 calls, and one of those seats.

Everything else is a gimmick to throw your money at.
