At De Boer Marine, we deliver all kinds of compasses. GPS compasses, gyro-compasses and fluxgate compasses are available from several manufacturers.


A gyrocompass, gyroscopic compass or toll compass is a gimbaled and electrically driven gyrotol that maintains a position in space once it has been occupied and is made looking north with the help of precession. It is used for navigation purposes and is preferred over a magnetic compass because of its higher pointing force, smaller errors and because it is not disturbed by iron objects or local anomalies in the Earth’s magnetic field.

GPS compass

The GPS compass determines the location and direction from the GPS signal. Two different antennas are used, the difference in distance then determines the location and direction. For each antenna the distance is calculated from the GPS satellite.

Fluxgate compass

A fluxgate compass is an electromagnetic device that uses two or more coils wrapped around a core with a high magnetic permeability. It receives the horizontal component of the earth’s magnetic field.

The advantage of the fluxgate compass over the magnetic compass is that the data is electrical and can be digitized and sent. The fluxgate compass can thus be linked to repeaters or an autopilot.
