A compass designed for boats and yachtsmen that demand absolute accuracy and a steady card in all conditions and heeling angles. It is flush-mounted, with an apparent scale size of 125mm and a gimbaled cradle. Features include the possibility to compensate for magnetic field disturbance, integrated illumination in the adjustable protection cover for ideal night vision and counter-balanced lubber lines that remain vertical even in rough seas. The extended center needle eliminates parallax errors and facilitates off course bearings.
