Marine Telescopic Alidade

Marine Telescopic Alidades are navigational instruments used in marine and naval applications. They are part of the supply class Navigational Instruments, which falls under the supply group Instruments And Laboratory Equipment.

A Marine Telescopic Alidade is a device used for measuring horizontal angles and determining the direction of a distant object or landmark. It consists of a telescope mounted on a rotating base, with a graduated scale and a sighting mechanism. The telescope allows for precise sighting and magnification of the object, while the rotating base and graduated scale enable the measurement of angles.

These alidades are commonly used in marine navigation, surveying, and cartography. They are particularly useful for determining the bearing of a distant object or landmark, which is essential for accurate navigation and mapping.

In summary, Marine Telescopic Alidades are navigational instruments used for measuring horizontal angles and determining the direction of distant objects. They are part of the Navigational Instruments supply class in the Instruments And Laboratory Equipment supply group.
