The SIGMA model is a steering and bearing compass, which is suitable for use on larger yachts. A typical installation location is the sliding hatch or garage, so that a reading can be made from the steering position. The compass itself can be removed from the mounting plate, e.g. to stow it safely below deck. The mounting plate already includes B+C and K (heeling compensations). A mounting plate without compensation is also available as an accessory for this purpose.

With the supplied shadow or bearing pin an astronomical deviation check can be carried out. An azimuth device is available as an accessory for the SIGMA model.
