Plastic Marine Compass with Internal Night Illumination
Plastic Marine Compass with Internal Night Illumination is a sort of automatic fluid-filling compass. It equips with high quality plastic housing which makes the shape and appearance look beautiful and elegant. Compared with dry compass, it has good stability when ships waggle. In addition, strong directive force magnets and new lightweight composite dial allow fast performance. This compass is ideal for small and medium sized civilian vessels. There are 4 models we can offer in the series: CPS-90MD, CPS-100MD, CPS-130MD, CPS-150MD. All the products are designed and manufactured to meet the technical requirements of ISO-449A and GB/T3896-83A standards. If you have additional requirements, please contact us at any moment.

Compass deviation adjustment simple illustration
Principle of compass deviation adjustment: using same magnitude but opposite in direction of man-made magnetic force to counteract the effect of vessel magnetic filed to the compass.
First use marking or sun positioning methods to measure the compass deviation.
Use the side magnetic bar in the compass box to correct the A vertical component magnetic field. When the A component is “positive”, place the positive end of the bar toward the head of the vessel. When the A component is “negative”, place the negative end of the bar toward the head of the vessel to eliminate the deviation.
Use the front magnetic bar in the compass box to correct the B horizontal component magnetic field. When the B component is “positive”, place the positive end of the bar toward the right side of the vessel. When the B component is “negative”, place the positive end of the bar toward the left side of the vessel to eliminate the deviation.
Suitably adjust the up and down position of the magnetic bar to eliminate the C Component which causes the inclination deviation.
