The Brunton TruArc 10 Global Compass is a globally balanced compass designed for adventure racers. It provides an accurate reading anywhere with a rare-earth magnet that resists interference and will not lose polarity. Its 1°-resolution azimuth dial, north-pointing needle, direction-of-travel arrow, and vial bottom will glow in the dark for up to 8 hours. Quick reference cardinal points and high visibility clings deliver information quickly, even in low-light settings. The TruArc 10 has a reversible slide scale, GPS confidence circles, a magnified readout and a double-gauge base plate.
