The Conventional Pocket Transit (0-90°) from Brunton is an analog navigation device built to resist magnetic interference and deliver accurate readings. This configuration of the Transit series uses Alnico II magnets to resist demagnetization and align with magnetic north better than most magnetic materials. An induction dampened needle and V-cut sapphire bearing improve the accuracy and speed of readings. For enhanced reliability and accuracy, the cast aluminum housing can be tripod mounted with Brunton's ball and socket 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.
