This F5006LM Brunton Pocket Transit features a single NdFeB magnet that resists demagnetization better than other types of magnets for increased reliability. The compass needle has a sapphire jeweled bearing and is induction damped needle for quick and high accurate readings. 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). 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. 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). Closing the compass lid moves a needle lift mechanism that protects the jewel bearing when transporting the compass. This model F5006LM is accurate to 1/2 degree in azimuth, and has a 10 arcminute resolution for vertical angles. The compass measures 2 3/4 inches (7 cm) by 3 1/16 inches (7.8 cm), is 1.25 inch (3.2 cm) thick, and weighs 6.5 ounces (184 grams). The F5006LM has a National Stock Number of NSN 6675-01-127-8394.
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 geologist's most trusted tool, combining the principles of the surveyor's compass, prismatic compass, clinometer, hand level, and plumb. The Brunton Pocket Transit is still made in the USA and comes with a one-year warranty.
The optional Brunton Ball and Socket Tripod Mount is a must for high accuracy readings. This exclusive mount fits all Brunton transits and is adjustable for both azimuth and vertical angle measurements. The Brunton Ball and Socket Tripod Mount is precision manufactured using non-magnetic aluminum and brass materials. The Ball and Socket Tripod Mount with standard 1/4 - 20 threads has a National Stock Number of NSN 6675-00-799-2963. The optional Brunton Ball and Socket Tripod Mount is 3 7/16 inches (8.7 cm) wide by 3 1/2 inches (8.9 cm) tall, 13/16 inch (2.1 cm) thick, and weighs 4.4 ounces (125 grams).
