Hand-crafted of non-reflective, soft camouflage rubber and equipped with a hand-tuned, quick-change reed and a matching braided, nylon lanyard. These are super effective for calling all North American predators-coyote, bobcat, fox, wolf, mountain lion and bear. You’ll appreciate the solid, comfortable feel of the ribbed body and the extra volume produced by the stepped-tone sound chambers. For the experienced predator caller who wants full control. A favorite among professional callers.
