ABSTRACT:
An underwater propulsion device for propelling a swimmer through the water has a hand held propulsion unit which permits the swimmer to move his hand and forearm to control direction of movement in the water. This allows superior maneuverability in the water. The device includes in combination, a power unit for attachment to the body of a swimmer, the power unit containing a power supply and a sealed motor; a propulsion unit having a propeller within a cylindrical housing, a hand grip on the outside of the housing for a swimmer to hold, a strap on the housing behind the hand grip to fit over a forearm of a swimmer to support the propulsion unit from the forearm. The handgrip has operating controls thereon the the motor. A flexible drive extends from the motor in the power unit to the propeller in the propulsion unit.
