An underwater propulsion unit comprises two sections, one of which contains the motor and battery A, and the other the propeller D. The two sections are magnetically coupled together and attached to the air tank B. An on/off switch E is attached by a wire to the motor housing and comprises a reed switch (69, fig 6) and a light emitting diode (67, fig 6) in the handle (63, fig 6). |
