The ComPro Pocket Transit Compass (0-360°) from Brunton is a specially engineered analog navigation device built to resist magnetic interference and deliver accurate readings. This configuration of the Transit series uses a round rare-earth magnet to resist demagnetization and align with magnetic north better than other magnetic materials. The needle's reduced center of gravity is designed to minimize needle dip when used near Earth's magnetic poles. The molded composite compass housing is silicone sealed for waterproof performance, and is compatible with Brunton's ball and socket tripod mount. 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.
