My advice to beginner hunters is less is always more. Don't try to be to agressive like you see on TV shows, they are trying to get good gobble footage. If a bird starts working your way or pitches off the limb in your direction, most of the time the deal is made. Simple 3 to 4 note yelps has killed alot of birds and over aggressive calling has saved alot as well. The more they gobble, the better the chances are for another hunter to close in on you or him gobble up a hen.
