Abstract: A retractable, vertically-aligned, transom-mounted transducer holding device that allows for the movement of a transducer, or similar sensing devices, from beneath a boat hull into a position raised above the waterline of the boat is disclosed. A bifurcated alignment rail allows slidable positioning of a non-metal support plate along the length of the rail. The support plate is selectively positioned along the support rails via a mechanical lever. The support plate may be placed in an operating position, at the lower end of the rails, or in a storage position, at the top portion of the rail.
