Magnetic compasses provide a heading indication on board independently of satellite-based navigation systems. In commercial shipping they are used as steering, bearing, reflection or lifeboat compasses. The appropriate design depends on both purpose and installation: options include console, bulkhead, overhead and table mounting as well as compasses fitted in brackets. Gimballed or fully gimballed suspension allows the compass to accommodate the vessel’s rolling and pitching motion while keeping the card readable.
TOPLICHT supplies magnetic compasses with flat or spherical housings and a range of card diameters and graduations. The selection includes steering compasses for the wheelhouse, bearing and reflection compasses for heading and relative bearings, and compasses for lifeboats and rescue boats. MED and SOLAS approvals are specified for various models, while selected lifeboat compasses also comply with ISO 25862. For use after dark, versions are available with 12 or 24 volt lighting or multivoltage illumination.
The range is complemented by equipment for installation, bearing and compass correction. Accessories include bearing sights, steering lenses, mounting brackets, deck plates and B+C compensation systems. Compensation magnets are used to correct influences from the vessel’s own magnetic field. Installation therefore requires consideration not only of readability from the steering position, but also of the mounting location and possible magnetic interference on board.
