Make your duck hunting more productive with the Power Hen PH-2 Duck Call from Zink Calls. This call was designed for hunters who like the sound of a single reed but want to eliminate the "over blow squeak" of a single-reed call. With a pure duck sound and the ease of use provided by a double-reed call, this call offers the best of both worlds. Great for close-in calling or calling shy ducks. Mallard Green Polycarbonate.
