Abstract
A sonar transducer assembly for a fishing boat provides electrical signals corresponding to an image of the area surrounding the boat on both sides thereof based on sound echoes received by the transducer assembly. The transducer assembly comprises a transducer housing mounted on the transom of the boat so that the bottom surface thereof is at substantially the level as the hull of the boat in the normal position of the transducer housing, and such that the transducer housing can move rearwardly and upwardly in response to hitting an object in the water. The housing is generally bullet-shaped and houses a plurality of individual transducers directed in different directions away from the hull of the boat so as to provide scanning of areas of the water beneath and on both sides of the boat.
