Popular Turkey Calls The favorite choice of turkey calls among the hunters this spring have been the Purple Heart Over & Under and the Slate Zebrawood calls. The Purple Heart has a beaded glass top and and slate bottom. The Glass top has a clear sound to it and and slate has really great sound for clucks and purrs. The Zebrawood with the slate top has a great all around sound to it with hen yelps, clucks, purrs and even kee kee sounds. Both are beautiful calls and fit nicely in your hands! Don't forget to watch our Video demonstrations for each of the "Pro Gane Calls" Turkey Calls!
