SILVA COMPASS 100BC MS 100BC is a front reading compass with a solid bracket that enables various mounting alternatives, including on the headlining. It has a main steering scale on the horizontal part of the compass rose and direct reading on the vertical edge. This makes the compass ideal for boats with a sitting as well as a standing helmsman. The integrated illumination makes night navigation easier. The built-in compensator allows you to adjust the compass if it is disturbed by a magnetic deviation.
