How to choose this product
magnetic-compass

The magnetic compass is an instrument containing a magnetized needle which reacts to the earth's magnetic field by pointing to magnetic north. All ships must carry such a device. NauticExpo offers compasses for ships, binnacle or bracket-mounted compasses, hand-held boat compasses and other models.

Applications

These compasses indicate a ship's magnetic course.

Technologies

The compass needle pivots around the center of a circle, the compass card, or rose, whose circumference is divided into 360 degrees. The 0° mark indicates north, 90°, east, etc. The compass may be dry or wet. In dry models, the needle is mounted so as to minimize friction. In wet models, the rose is immersed in a solution of distilled water and alcohol.

On merchant ships, the compass sits in a binnacle, a housing containing magnets to correct for the disturbance of the earth's magnetic field by the vessel's ferrous and electrical elements. Installation and correction of a magnetic compass on a merchant ship must be done by an expert.

How to choose

It must be remembered that magnetic north does not coincide with geographic north, and that the earth's magnetic field varies from area to area around the globe. Some models can display compass readings on the radar screen or integrated bridge instrument systems.

Advantages

- Needs no power source

Disadvantages

- Affected by artificial magnetic fields
- Requires compensation and correction
