The Axis was designed by geologists for geologists to enable easier, more intuitive geological measurements.  It features a revolutionary twist on traditional pocket transits!  The Axis can measure EVERY ANGLE, EVERY DIRECTION.

Product Features:

  • Innovative dual-axis, hollow hinge allows for efficient, accurate measurements of planes, lines, bearings, and inclinations.
  • Only one measurement configuration is needed for each measurement type.
  • Compass North is oriented parallel to the main hinge which rotates 360°, making the Axis the only transit that can measure strike and dip simultaneously, on any surface!
  • The novel lid protractor and 360° rotation around minor axis make the Axis the only transit that can simultaneously measure trend and plunge, even on overhanging surfaces!
  • The hollow sighting tube through the hinge eliminates the need for a mirror and sighting arm.

Axis Details:

  • Adjustable needle locking mechanism
  • Hard anodized aluminum billet body
  • Vial levels on each side for easier leveling
  • Round level on compass face
  • Magnetic declination adjustment for east or west
  • O-rings for waterproof protection of compass internals
  • Manufactured by Brunton in Riverton, WY
  • Limited lifetime warranty through Brunton

  1. Adrianne Stinson

    Great transit Brunton! Couldn’t be happier with my purchase! The Axis is light years ahead of the Compro (the plastic one) and makes measurements at least 4 times as fast. It works differently than all of the other Bruntons I’ve used and honestly I’ll never go back! You can take two measurements at the same time like trend/plunge and strike/dip and it has radically cut down my ‘on outcrop’ time in the field. Innovative and long overdue in functionality, bravo!!

  2. Jeff Rangell

    The Axis is a great transit and a significant step up from Brunton’s other transits! It is well made, takes care of all standard geologic measurements quickly and has an interesting 2 axis hinge that sets it apart from the other transits that I’ve used. Highly recommended if you spend lots of time in the field or want to use the transit of the future!
