Guiding you in the right direction every time out, Ritchie® Marine Compasses feature the most modern marine compass components to ensure every boating adventure is worry and trouble-free. The Helmsman™ HF-742 and HF-743 are designed for 25-35 feet power or sailboats and both sport large 3-3/4'' CombiDial™ dials. These incredibly accurate dials are encased in domes made with a heavy-duty, optically clear polymer to provide clear and accurate magnification of the dial. Equipped with a bi-axis gimbal system to ensure normal operation within their environment without bottoming out due to the pitch and roll or heel of the boat, these compasses' bowls and housings are made from high-strength glass reinforced polymers. Since deviation occurs when something on board your boat draws the compass magnets away from the earth's magnetic field, all Ritchie Marine Compasses have built-in compensators. These compensators are non-interactive magnets that are balanced and optimally spaced for accurate correction. Compensation instructions are included.
