Gyro Compasses are the most reliable Gyro Compasses on the market and with no liquids to change every other year like most other gyro compasses, they are virtually maintenance free. A wide range of control units provide complete flexibility of system configuration for new installation and easy retrofit into existing repeater systems. The standard range of interfaces can easily be expanded to provide signals for all vessel applications. The distribution of power and heading signals from the control units enables practical installation and easy retrofit. The unique technology in the GC85 and GC80 gyrocompasses eliminates “practically” the need for annual service. The GC85 and GC80 are fully IMO approved for standard and High Speed Craft (GC85) and can be configured in a dual gyrocompass system. The highest possible accuracy and stability is provided from new technology, by sophisticated and fully sealed sensitive element.
