If you know where he is going and can be there before him, set up in that area and call very sparingly and very quietly after you know he is on the ground and getting close to you. He is probably just following the hens and will give you some courtesy gobbles. When the hems all go to nest, he will come looking for you. I would also suggest using one of those camo screens with the stakes so that you are comfortable to wait him out. That way your legs are hidden when you need to stretch a little. It also helps hide your movement when moving your gun. And I try to scratch leaves when I am repositioning myself. Use the hen scratching cadence, 1,2 pause, 1,2, 3 pause, then 1. Maybe throw in a little soft purr or two.
