The Aviator 3D has the added feature of full body motion. A motion stake allows the Aviator 3D to rock forwards and backwards as well as pivot side to side. No rechargable batteries or charger to buy. 3 "AA" batteries power the Aviator 3D for an entire day. It comes complete with 2 motion stakes for field use. A half inch conduit (not included) will raise the Aviator 3D for greater visibility or for use over deeper water. The Aviator 3D provides a fresh, new look to a spinner on a pole and the ducks love it !!!
