ABSTRACT:
A mounting apparatus for the sonic transducer of a directional Doppler fish-finder includes an elongate tubular control arm and a clamp assembly for attaching the control arm to the side of a boat so as to extend along and pivot about a generally vertical axis. The upper end of the control arm includes a pivotally mounted control lever, and the lower end includes a pivotally mounted transducer mounting plate to which the transducer is attachable. The control lever and the mounting plate are interconnected by a pair of cables extending through the tubular control arm, whereby pivotal movement of the control lever causes pivotal movement of the mounting plate about a generally horizontal axis. Pivotal movement of the mounting plate about both the vertical and horizontal axes enables a fisherman to direct the sonic signal of the transducer in a locus of directions representing semispherical coverage of the water about the boat.
