The Haydel's Game Calls Diver Duck is a specialized tool engineered specifically for dedicated diver hunters. Crafted from high-density black acrylic, this call replicates the coarse, guttural brrrrr and purring sounds used by Redheads, Bluebills, Scaup, and Canvasbacks. It features a single-reed setup that allows for a wide range of inflection and a removable plug in the exhaust barrel for added volume and projection over open water. Equipped with a double O-ring seal for an airtight fit, this open call provides the sharp resonance needed to cut through high winds and large spreads, offering a authentic alternative to traditional mallard calls. Safety Note Diver duck calls are often used at high volumes; avoid blowing the call at full strength in enclosed spaces or near the ears of partners. Regularly rinse with lukewarm water to remove saliva and salt spray.
