Brunton Geo Pocket Transit

Our commitment to our roots continues with the GEO™, the newest and most advanced transit we build. Listening to owners of our pocket transits, and implementing some of their ideas, we have created the ultimate tool for professionals. Our billeted aluminum, waterproof GEO Transit contains a fast, magnetic north seeking, rare-earth magnet, balanced on a sapphire jewel bearing for quick measurements.

The most noticeable feature is the hinge inclinometer, accurate to +/- 1/2 degrees. This feature allows simultaneous trend and plunge measurements reducing the number of measurements you must take in the field. An innovative needle design can be locked or unlocked depending on your requirements. The ultimate tool is yours to cherish.
