Nothing sends a better "all is clear" signal to flying waterfowl than the sight of feeding ducks. And these Drake Quiver Duck Butts are the easy, effective way to mimic that behavior. They sport a Quiver Magnet H20 permanently mounted in a durable, lifelike closed-cell foam decoy body. Simply turn it on, toss it into your spread and get ready to shoot. The Quiver Magnet creates realistic feeding movement that produces ripples on the water’s surface. Weighted keel with anchor attachment. Requires two AA batteries (not included). Batteries are easily accessible. Available: Mallard Drake.
