compass, prismatic compass, clinometers, spirit level & plumb. This compass is the famous Brunton Compass designed
by Colorado mining engineer D. W. Brunton. In 1894 Brunton received a patent for his new compass and within a few
years it became widely used throughout the world. Since Brunton’s patent has expired, other high-quality and low-cost
pocket transits have been introduced to the market. Still, the Brunton Compass remains many geologists’ most trusted
tool, combining the principles of the surveyor’s compass, prismatic compass, clinometers, hand level, and plumb. It
unfolds to produce two sights with peepholes. You can either sight through a clear window in the lid or lay the lid fully
open and use the second hinged peep sight. The inside cover has a mirror with a vertical line inscribed. The perimeter of
the face has a compass rose and the interior of the compass rose has two spirit levels and a movable scale for use as a
pocket transit. There is a slotted screw on the outside of the case that turns a gear that rotates the entire compass rose
to adjust your local magnetic declination angle (the difference between true north and magnetic north). Closing the
compass lid moves a needle lift mechanism that protects the jewel bearing when transporting the compass. Turning the
compass on its side and adjusting the spirit level allows for an altitude angle measurement (while viewing the spirit level
using the mirror hinged at 45-degrees). This model is accurate to one degree in azimuth, and has a 10 arc minute resolution
for vertical angles.
