The Brunton Axis Pocket Transit Compass is a revolutionary compass designed specifically for geologists by geologists. Its unique features and design make measuring planes, lines, bearings, and vertical angles a breeze.

With a dual-axis, hollow hinge, this compass eliminates the need for multiple read-outs or different measurement tools. It can be easily configured to measure strike and dip, trend and plunge, bearing and vertical angle, all in one setup.

What sets the Brunton Axis apart from other transit compasses is its main hinge axis, which runs parallel to the North. This allows for simultaneous measurement of strike and dip, making it the only compass of its kind. Additionally, the compass has a lid protractor that can rotate 360-degrees on both major and minor axes. This enables accurate measurements on any plane or surface, including overhangs.

Another noteworthy feature of the Brunton Axis is its adjustable declination. This ensures accuracy across North America without sacrificing precision. The compass is available with either a 0 to 360° azimuth scale or a 0 to 90° quadrant scale to suit your specific needs.
