An improved remote-controlled, aquatic locator apparatus includes a base unit comprising detector controls, steering controls, and propulsion controls; and a mobile unit comprising a transducer, a steering mechanism, and a propulsion mechanism. The detector, steering and propulsion controls communicate with the transducer and the steering and propulsion mechanisms, respectively, by a buoyant multiconductor cable connecting the base unit to the mobile unit. A first modified apparatus includes two transducers, one directed generally downwardly and the other directed generally laterally to simultaneously provide different views. A second modified apparatus provides a base unit and a mobile unit which communicate wirelessly by a pair of transceivers, one in the base unit and the other in the mobile unit. A third modified apparatus includes an extendable rod for maneuvering a mobile unit toward and away from a base unit near a user.
