Abstract: Apparatus for mounting an acoustic transducer in connection with a boat to allow the transducer to be moved about beneath the water and thereby scan more than one direction. The apparatus comprises a flexible control cable with a device which actuates it fastened to the cable's upper end. Fastened to its lower end is a pivot mechanism which converts the action of the control cable to a pivotal movement. This pivot mechanism holds a transducer support mount such that the action of the control cable pivots the transducer support mount; preferably, in a vertical plane. The pivot mechanism is connected with the boat such that the pivot mechanism and the transducer it holds are held beneath the water; and, preferably, such that the transducer mount can be rotated 360.degree. about the vertical axis, as in a substantially horizontal plane.

Abstract: A bracket for mounting an acoustic transducer to a boat or the like to allow the transducer to be used as a depth sounder or as a scanning device. The bracket comprises a shaft; support means for coupling the shaft to a boat with the shaft located with its lower end in the water; a transducer supporting mount pivotally coupled to the lower end of the shaft for pivotal movement about an axis transverse to the shaft; means for rotating the shaft 360.degree. about its axis; and means for pivoting the mount between different angular positions to allow vertical and generally horizontal signal transmission and reception.
