Marine Binocular Alidade

Marine Binocular Alidade is a type of navigational instrument that falls under the supply class Navigational Instruments in the supply group Instruments And Laboratory Equipment.

A binocular alidade is a device used for measuring horizontal angles and vertical angles in navigation and surveying. It consists of a pair of binoculars mounted on a rotating base, with a graduated scale and a sighting mechanism. The binoculars allow for magnified viewing of distant objects, while the rotating base and graduated scale enable the user to measure angles accurately.

In marine navigation, binocular alidades are commonly used for taking bearings of landmarks or other vessels. They are particularly useful for determining the relative position and distance of objects at sea. The sighting mechanism allows the user to align the binoculars with the object of interest, and the graduated scale provides a reference for measuring the angle.

Marine binocular alidades are designed to withstand the harsh conditions of the marine environment, including exposure to saltwater, extreme temperatures, and vibrations. They are typically made of durable materials such as brass or stainless steel, and may be equipped with features like waterproofing and shock resistance.

Overall, marine binocular alidades are essential tools for navigators and surveyors, providing accurate and reliable measurements for safe and efficient marine operations.
