Crafted using state-of-the-art injection molding technology, Zink Calls' new Thunder Ridge Series guarantees you'll find the same quality and consistency not only in every call, but in every note. Whether at 150 yards or 15 feet, this innovative call provides a fantastic range of sound, with one common denominator - it drives gobblers wild! The Thunder Ridge Series includes a two-piece hardwood striker; a slate-specific, an aluminum-specific, or a crystal-specific conditioning pad is also included (corresponding to the call material), sure to take the hassle out of prepping the call's surface. It also Sports the popular E-Z Gripper Ring and built-in Striker conditioning pocket. Also included is a copy of Zink's latest DVD production, Turkey Time University Vol. II "Friction Calling Basics".
