Haha I get fired up thinking about turkeys and get to deep.
Is the property thick timber or open? Your best bet is to probably 1) start the morning at highest point where you can hear the best. If he gobbles, then make a move.

2) get turkeys on trail cam or scout before season and pattern them. They can get into routine especially if with a large group of hens that tend to spend day in same area.

I use a cheap slate pot call about 75%. Can?t even remember brand. Slate came easiest to me and it?s very versatile. I also use diaphragm.
