In an oscillating fin propulsion apparatus operatively connected to a scuba diver moving on or through a body of water, a propulsive force may be produced by a pair of fins adapted to sweep back and forth in a generally transverse direction relative to the longitudinal axis of the scuba diver's body. The fins may be mounted on opposite sides of a frame detachably secured to a scuba tank. The fins may be rotatable in an oscillatory motion about respective axes coplanar to the center longitudinal axis of the frame. Drive members operable by the scuba diver may be operatively connected to the fins. The oscillating fins may provide a propulsive force to propel the scuba diver longitudinally forward during both oscillating directions of the fins as they sweep back and forth.
