The Mallard Drake XS Pulsator is the ticket to adding portable water motion to your spread. Simply attach a decoy-cord and weight and drop into the water for a quick set-up. Unit has a built-in digital timer that surges a spray of water creating an ultra realistic rocking/feeding motion. Add multiple units to your spread and watch your decoys come to life. The XS Pulsator has an internal 12V 3amp lithium ion battery and timer that is built within the decoy housing which eliminates a traditional battery box attachment. Lithium Ion batteries are more durable, smaller and lighter in weight and are longer lasting versus the traditional lead acid batteries. No external battery box means less bulk and less weight. A single XS Pulsator can fit into most slotted decoy bags for easy transport. Recommended water depth is water as shallow as 6 inches.
