Rolling Thunder Game Calls Hunter Wallis Signature 3 Reed Bat Wing Diaphragm Turkey Call was designed by World and Grand National Champion, Hunter Wallis. It consists of three prophylactic reeds with a bat-wing cut and a relief cut in the middle reed. This signature 3 reed bat-wing call with thin prophylactic reeds is a perfect call for soft clear to raspy calling, making it ideal for callers who don't use a lot of air pressure. It's great for soft yelps, clucks and purrs, and light whistles. Hunter Wallis is by far the most decorated contest caller of his generation. With 9 Grand National titles, 2 World Championships, 2 US Opens, and 10 PA State Championships under his belt, he knows a thing or two about the way a yelper ought to sound. He completed his first grand slam at the age of 12, and at the ripe old age of 23 Hunter has completed several more. FeaturesProph construction3 reedBat-wing cut
