ABSTRACT:
A retractor device is provided for selectively positioning a depth gauge transducer into the water and below the bottom line of a pleasure boat or retracting the transducer to an upwardly facing position above the water line. A compound lever system is mounted via a mounting bracket to be positioned adjacent to and above the normal water line of the boat. Alternately, the mounting position can be under the water line. This lever system includes a transducer carrying lever arm linked to an activator lever arm. These two lever arms are intended to rotate about there own individual pivot point on the mounting bracket and are linked with connection links at points intermediate their ends thereby causing the two levers to rotate together and have a bias to either of two rotational positions, the first being an extended position for the transducer into the water and the second being the retracted position above the water. In the extended position, the transducer carrying lever arm extends into the water to a point below the bottom line of the boat. Detents operating between the activator lever arm and the mounting bracket establish intermediate fixed rotational positions for the lever arms.
