Creates movement so natural, you'll think your spread is full of live ducks. Used by the "Duck Commander" Phil Robertson, it sets up like a jerk string, but has no cord to pull. The included remote control programs swim speed and swim distance from well outside the spread for hands-free hunting. There's no long, tangle-prone jerk string, so it's safe from spread-crashing dogs and hunting partners. For water depths up to 30". Requires one 12-volt marine battery (not included). Made in USA.
