The Zink Polycarbonate Ph-2 Mossy Oak Shadow Grass Blades Duck Call is a double reed for the hunters who like the sound of a single reed. It wrangles an impressive range of pure duck sounds without the "over blow squeak" single reeds often create. Use this bad boy for close-in calling or shy ducks. The goal of Zink Calls is to promote waterfowl and turkey hunting in a traditional, ethical, responsible and enjoyable manner. The custom line includes one-of-a kind calls with hand-selected wood and unique acrylic rods. Even if you don't select a custom design, you still get custom quality; all calls are hand-tuned and perfected before they leave the shop. It's this dedication to quality that has earned Zink respect and admiration among hunters and competitive callers alike.
