Abstract

An apparatus mounts a sonar transducer to a boat. The apparatus includes a tubular member with a handle at one end and a transducer mounting bracket at the other end. The transducer mounting bracket is adapted to couple to a sonar transducer. Both the handle and the transducer mounting bracket are pivotally coupled to the tubular member and to each other by a linkage rod. By moving the handle up or down, the transducer mounting bracket will move correspondingly to a new elevational orientation. In one embodiment, the tubular member is received by a cylindrical bore in a ball; the ball is mounted to the boat. By turning the handle to one side, the tubular member and the transducer mounting bracket will correspondingly turn to a new azimuthal orientation. In another embodiment, the tubular member is received by a sleeve mounted in a pivotable ball. The tubular member can move relative to the sleeve. Locking nuts on the sleeve, when tightened, prohibit movement of the tubular member. Frictional adjustments are provided at the handle and the transducer mounting bracket.
