This feeding mallard decoy creates just the right amount of ripples and does it without jerk cords or electrical wires running back to your blind. The 12-volt rechargeable battery and 6-ft. power cable are contained in a submersible, waterproof case that acts as a decoy anchor. A built-in timer surges a spray of water every .5 seconds to perfectly simulate a feeding duck. Use multiple pulsators for a realistic full-spread feeding motion. After the hunt, simply open the battery box and recharge the battery with the supplied charger. Mallard Drake only. Per each.
