C20-00128

Magnetic Compass · Position & Heading

Class-certified type (DNV register) · technical data sheet not yet verified

AUTONAUTIC C20-00128 is a marine magnetic compass. It is normally installed on or near the bridge in a position selected to minimize magnetic disturbance and provide the required steering or bearing reference. Its primary purpose is to provide an independent heading indication using the Earth's magnetic field. Unlike gyro or satellite-based heading systems, the magnetic compass requires no electrical power for its fundamental heading function. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.

Free of charge — send us your request for AUTONAUTIC equipment. Our team checks it and replies by e-mail.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — attach it below or send it as a reply to our confirmation e-mail.
