Brunton International Transit, 0-360 Degree GPS Receiver

The Brunton Transit International Compass (model: F5006LM0 is the famous Brunton Compass designed by D. W. Brunton, a Colorado mining engineer. After obtaining a patent for his new compass in 1894, Brunton soon had a compass that was widely used throughout the world, in only a matter of a few years. Brunton's patent has long since expired, and now other high-quality and low-cost pocket transits have been introduced to the market. Even so, many geologist's regard the Brunton Compass as their most trusted tool, combining the principles of the surveyor's compass, prismatic compass, clinometer, hand level, and plumb. When the compass is unfolded, it produces two sights with peepholes. You have the option to sight through a clear window in the lid or lay the lid completely open and use the second hinged peep sight. The interior of the cover features a mirror with a vertical line inscribed. This model F5006LM is accurate to 1/2 degree in azimuth, and has a 10 arcminute resolution for vertical angles. We
