This is the Brunton TruArc™ 15 Compass, each is made in Riverton, Wyoming and can be ordered with a unique Global Needle that works equally well north or south of the equator.

Brunton was originally founded in 1894 by D.W. Brunton, a Canadian mining engineer who was working in Aspen, Colorado at the time. His first and arguably most important invention was the pocket transit, a portable and compact version of the bulky surveying transits commonly used at the time.

A pocket transit, also known as a Brunton compass or a geologist’s compass, is a compact, precision instrument used for measuring angles in surveying, mapping, and geological fieldwork. It consists of a circular, liquid-filled compass with a sighting arm attached to the top of the compass housing.

Pocket transits were initially used by surveyors and engineers, but by the time World War 1 began in 1914 the military uses of the pocket transit became quickly apparent, and many were made for the United States Armed Forces.

Brunton soon began to manufacture a series of compasses for orienting and exploring, this line of compasses soon became renowned in the USA and around the world for their quality and reliability. Later in the company’s history in 2010 almost all of the manufacturing was brought back to the USA from China, at the company’s Riverton, Wyoming factory.
