ABSTRACT:
A mounting apparatus for mounting a sonar transducer assembly to an aquatic vehicle, particularly for fish finding and mapping devices. The mounting apparatus permits the transducer assembly, typically extending beneath the hull of a boat, to "kick-up" when contacted by a predetermined force such as when colliding with an underwater obstacle. The mounting apparatus includes a mounting member including a ratchet surface for matingly engaging a complimentary ratchet surface of the transducer assembly. The ratchet surfaces will give way upon contact with sufficient force permitting the transducer assembly to pivot upwardly and rearwardly to protect the transducer and prevent it from being sheared from the aquatic vehicle.
