They consist of an off-the-shelf R\/C servo installed in a machined enclosure with a titanium output shaft and waterproof connector. This architecture leverages decades of servo development in the R\/C industry to provide extremely high reliability as well as almost limitless options for speed, torque, travel distance, and other features, all at a fraction of the cost of other subsea actuators.\u003c\/p\u003e\n\u003cp\u003eWe offer four models of Underwater Servos, each available with an all-acetal enclosure rated to 200 meters depth or a combination acetal\/anodized aluminum enclosure rated to 400 meters depth.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe SER-2010 (200m) and SER-2011 (400m) feature the Hitec D954SW R\/C servo.
