and a circle-over-circle north indicator. To answer criticisms of the previous Eclipse design, Brunton incorporated several design changes including a deep-well 'global' vial, a serrated outer bezel, and map meridian lines imprinted in the base of the housing (to aid in map orientation). Unlike older Eclipse compasses, O.S.S.™ compasses were assembled in Riverton, Wyoming from components made in the United States. As of 2012, Brunton was the only major compass manufacturer with U.S.-based production facilities. In 2014, Brunton dropped the circle-over-circle magnetized disk/needle design used in the Eclipse and O.S.S. series, and returned to a traditional needle design for the magnetic north indicator. The current TruArc™ baseplate compass line uses rare-earth magnets to stabilize the north indicator needle. Equipped with 'deep-well' liquid-filled capsules, all TruArc™ compasses were designed from the outset to work in all magnetic zones. In 2016 Brunton introduced the Axis Pocket Transit (F-5011 and F-5012) intended specifically for geologists. The Axis Pocket Transit offered for the first time simultaneous measurements of strike, dip, trend, and plunge in a variety of configurations. The Axis Pocket Transit features an unconventional lid design that swings a full 360 degrees in both directions and two axes that allow precise measurement of vertical and horizontal angles on all configurations of bedding surfaces. It also breaks from traditional transit functionality in orienting north in-line with the major axis and in sighting through this hinge without the standard mirror and sight arm. Brunton launched a new series of illuminated field survey instruments and general outdoors (baseplate-style) compasses at the OutDoor show in Friedrichshafen, Germany, June 18, 2017. The Omnisight LED is a lensatic (direct-sighting) surveying compass reminiscent of the previous Brunton Clinomaster, but with LED illumination. The compass is also available with a built-in clinometer as the Omnislope LED. Brunton introduced new photoluminescent dials to its TruArc™ line of compasses, and reintroduced the older Brunton 8010 (Smoke Chaser™) compass with clear baseplate, now incorporating a new photoluminescent dial marked in degrees. A version using an MRAD (mils) scale has since been discontinued. GPS receivers In 2000, Silva of Sweden AB introduced its Silva Multi-Navigator GPS device. Brunton marketed the product in North America as the Brunton MNS™. The MNS featured an electronic compass, barometer, and barometric altimeter in addition to GPS functionality. With a relatively high energy consumption of 210 mA (or 270 mA with illumination on), the MNS had a battery life of
