The GEO Pocket Transit Compass (0-360° Scale) from Brunton is a specially engineered analog navigation device built to deliver fast and accurate readings. This configuration of the Transit series uses a single rare-earth magnet to resist demagnetization and provides fast readings due to its relative magnetic strength. A hinged clinometer allows simultaneous trend and plunge measurements that are accurate to +/-2°. The compass housing is machined from a single billet of 6061-T6 aluminum and is o-ring sealed to provide waterproof performance. Brunton Outdoor Group has been designing and manufacturing compasses since their establishment in 1894; whether you are a bird watcher, hunter, or hiker, Brunton has been making gear for nature enthusiasts like you for over a century.
