Description
The GFC-190 Marine Magnetic Compass Azimuth Circle is a high-precision navigational instrument designed for taking accurate azimuth and bearing measurements aboard marine vessels. It fits snugly onto Class A standard magnetic compasses with 190mm diameter bowls, enabling precise observation of celestial bodies, terrestrial targets and compass bearings from the bridge.
GFC Series Marine Magnetic Compass Azimuth Circles are used for magnetic compass CPT-190 or CPL-190 and are designed for all specifications of marine Class A magnetic compasses.
Key Specifications:
– Model: GFC-190 (Part No. GFC190-24105)
