ABSTRACT:
An electronic depth finder apparatus is shown for use in fishing and/or navigation, and it includes a combined impulse control means and read-out, as well as a remote cooperating transducer immersed in the water. The invention relates to a means of adjustably mounting the transducer on a boat so that the transducer may be capable of as many as three planes of movement; namely, swinging movement in a vertical plane, unlimited rotational movement in a horizontal plane about a vertical axis, and up and down vertical movement between a lower "searching" position and an upper "running" position. The upper "running" position allows operation of the apparatus when the boat is moving at high speeds.
