Function

Box sextant used for measuring angles on land. Series of reflecting mirrors can be used to obtain angles within 120? upon the surface of the land to within a single minute of the arc. During its time period it was popular with British surveyors as a land surveying instrument and also became popular in the military.

Technical

Manufactured by Elliot Bros. Box sextants were very portable instruments. They were protected from any type of injury because the box could be used to cover the instrument after removal, unlike nautical sextants which could be damaged by anything. Arc reads from -5? to 140?, and the vernier goes to 30?.
