Im going to turkey hunt this year and I know how to use a mouth call and just now learning a wingbone call. With the wingbone call is this for cutting or yelping only? Ive also found another call that I dont know what it is or what its for. Im pretty sure it came in a group of Knight and Hale calls. Its a cylinder about 2.25 inches long and about 1 3/16 wide. It completely open on one end and has half an opening on the other. The part thats half closed is covered by a piece of plastic that has a small opening 2/16 wide. Im guessing this is some type of shock call and have no idea how to use it. Help!!! Also what are some different ways to use a box call as I have one of those as well.
