In very good condition

A gyrocompass is a particular type of compass (also called directional or gyroscopic compass), that is a navigational instrument to find a fixed direction, not based on the earth’s magnetic field but on the gyroscopic properties.

The gyrocompass determines the direction of North using four physical laws: the gyroscopic inertia and the precession of the gyrostats, and two properties of the earthly sphere, the rotation around the axis and the force of gravity. Besides the operating principle of the gyroscope (that keeps the orientation fixed according to a fixed point in the space), there is the gravity force, applied with a weight on the cardan joints that keep the gyroscope in suspension. Together with the other applied forces, they create an accurate geographic pointing.

The compass works perfectly and is ready for the bridge of a ship or a yacht.

If you connect it to the electric power, it will light up for the night vision!

Dimensions: diameter 30 cm, length 26 cm.
