    Abstract: The underwater personal propulsion device is placed between the diver's lower legs to allow hands-free operation of the device by the diver. The device includes a pair of footrests extending laterally from its lower end, and a pair of braces or pads extending from the sides of the device to allow the diver to brace the device between his or her lower legs. A series of straps, e.g., bungee cords, extend from the upper end of the device to the diver's waist belt, e.g., the conventional weight belt, or to attachments or straps extending therefrom. Power control is provided by a controller installed on the diver's belt or, alternatively, by a foot or lower leg control. The device is easily aimed or steered by manipulation of the diver's legs, thereby allowing the diver to maneuver while his or her hands remain free for other operations.
