Sonar transducer assembly for fishing boats

In combination, a boat including a transom and hull, and a sonar transducer assembly for providing electrical signals corresponding to an image of the area surrounding the boat on both sides thereof based on sound echoes received by said transducer assembly, said transducer assembly comprising a transducer housing;

• and means for mounting said transducer housing on the transom so that the bottom surface thereof is at substantially the level as the hull of the boat in the normal position of said transducer housing, and such that the transducer housing can move rearwardly and upwardly in response to hitting an object in the water, said housing including a tapered nose portion and an elongate body portion and including a plurality of transducers arranged serially therein along the longitudinal axis of the housing and directed in different directions away from the hull of the boat to provide scanning of areas of water beneath and on both sides of the boat.
