Real ducks swim. So we built the ultimate decoy motion device. It's lightweight, compact, easily fits into a coat pocket or blind bag and sets up in minutes. Used to draw ducks "feet down" at close range, this is an updated twist on the jerk cord concept. Gives motion for up to 4 decoys and is used by professional waterfowlers worldwide. Recommended for water depths of up to 5 feet. Decoys not included.
