The Brunton Sightmaster™ (0-360°) has the functionality of both a handheld and a sighting compass with reciprocal and forward headings. The 1/4" thread on the underside of the compass enables tripod mounting for enhanced accuracy. A sapphire jewel heading, aluminum housing, and 10x sighting lens make the SightMaster a dual-function compass ready for navigation on the water or in the wild.
