Wild turkeys hear sounds best in the 1700-2000 cps range. With a resonating surface that is 200 percent larger than conventional friction calls, the Hunter's Specialties Ring Zone Friction Turkey Call reproduces the sound of an actual wild turkey. The outer ring on the call keeps your fingers off the calling surface to eliminate dampening the sound. The ceramic surface plays with the volume of glass and the forgiveness of slate. Striker and rougher pads are included.
