Abstract
An apparatus for oscillating a flotation device on a body of water comprising attaching a rigid extension having a buoyancy container to the flotation device, placing the flotation device in the body of water such that the buoyancy container is filled with water and the flotation device and rigid extension rotate to a vertical position, and pumping gas continuously to the buoyancy container such that the buoyancy container will rise to the surface, rotating the flotation device and rigid extension to a horizontal position, thereby causing the buoyancy container to fill with water, further causing the flotation device and rigid extension to rotate to the vertical position, and to so oscillate between the vertical and horizontal positions continuously. A supply device that pumps the gas is located within the rigid extension, the buoyancy container, or the flotation device, and when the supply device is contained within the rigid extension or buoyancy container, the rigid extension plus buoyancy container can be removably attachable to any flotation device. The invention is useful for oscillating a duck decoy in the water to simulate feeding patterns, making the decoy more effective.
