Higdon’s Swimmer decoys create the most realistic motion and ripple in your spread possible. Add this motion to these over-sized, high-contrast, realistic battleship Mallard Drake decoys, and you’ve got a deadly combination. Simply attach a decoy-cord and weight and drop into the water for a quick set-up. Decoy is powered by the included internal 12V lithium ion battery and timer that is built within the decoy housing that swims the decoy intermittently. This swimming motion naturally creates added realism to your set-up. The XS Swimmer decoy design has the battery and timer within the decoys 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 Swimmer decoy can fit into most slotted decoy bags for easy transport. Recommended water depth is water as shallow as 1 foot of water. Runtime: 7hrs. Fast recharge time of 6 hours. Package contents: decoy with attached 750GPH bilge pump, battery and timer pre-installed within the internal battery box, charger and operating instructions. A percentage of your purchase will go to Ducks Unlimited to help with their efforts for wetland conservation.
