once you have a gobbler responding and getting closer, all it takes is a soft cluck here and there, just enough to keep him moving and gobble a bit so you know which direction to have the gun pointed, when you can hear him snap as he gobbles (when you hear it you'll know what I mean) if your sure he cant see you (this is why I'm behind cover instead of in front of a tree) reach down and rake the leaves with your fingers, do it twice, a hen almost always scratches with one foot, then the other, then steps back to feed. this does 2 things, 1) the gobbler has heard hen calls, so he is 75% sure a hen is waiting for him, he hears the scratching that's further proof a hen is there, 2) it seals the deal and he speeds up coming in. turkey hunting ain't hard once you figure out how that hickory nut sized brain works.
