Brunton

Axis Pocket Transit Compass

The Brunton Axis Pocket Transit Compass is an innovative compass invented by geologists for easier measurements of planes, lines, bearings, and vertical angles. The dual-axis, hollow hinge facilitates quick, accurate measurements without requiring multiple read-outs or different measurement tools. Only one measurement configuration is required for strike and dip, trend and plunge, as well as bearing and vertical angle.

North runs parallel to the main hinge axis, making this compass the only Brunton Transit capable of measuring strike and dip simultaneously. The lid protractor rotates 360-degrees on both major and minor axes to allow accurate strike-and-drip and trend-and-plunge measurements on any plane or surface, including overhangs. Adjustable declination allows you to use this across North America without sacrificing accuracy. It's available in either a 0 to 360° azimuth scale or 0 to 90° quadrants.
