Its hard to lure a mature Tom across a field. He will most likely use the tree line or go through the woods to get there. But anything is possible I guess, also don't use the same call day after day he'll pick up on that .I try to set up on the same side he's roosted about a hundred yards away I'll will set out two hen decoys down from me about 25 yards out on the field so when he flys down he'll be able to see decoys and if he comes in he'll be watching the decoys and not you. I don't start calling to the song birds start sing, then only some soft yelps to start .When he gobbles I stop for 5 min or so then I Yelp and Cut then just stop for a while. He should have gobbled to that, then my next call I do is a Fly down crackle I use my hat instead of a wing. Most of the time that will get him to fly down. Then I use clucks and purrs on a slate to bring him in ... Hope this Help GOOD LUCK
