The Pocket Transit Geo Compass features a waterproof aluminum billet and sapphire jewel bearing for durability. Its induction damped needle settles quickly, and a single NdFeB magnet resists demagnetization for long-term accuracy. The precision-aligned mirror allows for accurate sighting of bearings and angles. It is compatible with ball-and-socket tripod mounts and comes with a leather case. Made in the USA.
