Mouth calls in the Kill Tone Series™ are the custom design of multiple winners of the NWTF Grand National Turkey Calling Championship and decades of hunting experience. Each Kill Tone Series™ call has unique cuts that offer realistic sounds and are consistent with each call. Consistency is the key to a mouth call and why most championship callers make their own calls. Color-coded tape ensures that you pick the right call when things get exciting!
