Descriere
Stația de indicator - Alamă, Lemn - 1940
Italia

Antique device used in coastal navigation to locate the ship's position on nautical chart, based on surveys on three known visible points. The station pointer, also known as three-arm protractor, consists of a circle, graduated from 0 to 180º in both directions, in the middle of which three arms are hinged: the central one is fixed on the zero, while the others are mobile. By positioning the three arms so that, when passing through the three points observed, they form the respective angles, the position of the ship is obtained. It is also used in topography.
Well-preserved in its wooden case.
