Do you ever wonder why some duck hunters always seem to come back with more birds than others? Chances are it's because they've put some motion in their decoy spread. With its realistic design, the Quiver Duck adds movement to your decoys, making them look more like the real thing to flying birds. Motion is created by the permanently mounted Quiver Magnet H2O located in the decoy base. The Quiver Duck uses two AA batteries (not included) and the battery compartment is easily accessible. A weighted keel makes sure your decoy stays upright, even in choppy waters.
