A gyrocompass detects the true north by means of a fast-spinning rotor, which is suspended with no friction and is influenced by gravity and rotation of the Earth. A gyrocompass consequently indicates a ship's heading. CMZ900 series has been type approved in accordance with International Maritime Organization (IMO) standards, resolution A.424 (XI) as well as JIS-F9602, class A standards. 

A modular design saves the space. Master compass can be integrated in the autopilot steering stand.  A unique anti-vibration mechanism enhanced by the velocity damping effect of high viscous oil, provides superior damping of vibration and decoupling of shock at sea. A small and lightweight container enhances the follow up speed. The gyrocompass reading changes smoothly and does not lag when a small ship rapidly changes course.
