The liquid contents is under constant pressure, I.E. approx. 3 bars at 28°C. The pressure may reach 8 bars at 78°C under extreme condition, I.E. approx. 90 kg of pressure on each glass of the compass. The latter are held in place by screwed rings. This compass required no maintenance for many years. It can endure pressures exceeding 100 bars without any difficulty. Precision is +/- 1°. It should be used with certain precautions. For example, it should not be used near devices which create a magnetic field of any magnitude. For optimum reading accuracy, it should be kept well away from any nearby metallic mass, such as guns, helmets, metal tables, etc. This compass is sealed in a water resistant container. Due to the transparency of the turning compass, you can use it directly on the map. The compass is only working in horizontal position. Specifics compasses for North or South hemisphere available.
