Brunton AXIS F-5012 compasses
Double Axis Inclinometer. The shaft was invented by geologists for geologists and features a significant new twist on pocket transit that is specially designed for easier geological measurements. Axis Transit can take simultaneous measurements of heading and dip, dip and dip azimuth, and trend and sink, making data collection easier and faster than ever.
Brunton is committed to building the most reliable and accurate navigation instruments on the planet. As durable precision instruments that undergo constant and often rigorous use in the field, to maintain their accuracy and integrity, they simply need to be repaired from time to time; just like you would tune your car or bike. Brunton offers complete repair and refurbishment facilities for most models. We appreciate your kind understanding.

Angular System


Designed by geologists for geologists, this unique instrument allows you to collect measurements and data much more efficiently than with traditional transits. The patented design of this transit makes difficult field measurements extremely easy and allows multiple measurements to be collected at once. The needle can be set to lock automatically, ensuring accurate readings when the face of the instrument is not visible.

The shaft was invented by geologists for geologists and features a significant new twist on pocket transit that is specially designed to facilitate geological measurements. Product details The innovative dual axis hollow hinge allows intuitive, efficient and accurate measurements of planes, lines, bearings and vertical angles. Only one measurement setting is needed for strike and dip, trend and dip, orientation and vertical angle, increasing the efficiency and accuracy of measurements. Compass North is parallel to the main axis of the hinge, making the axis the only transit capable of measuring heading and dip at the same time, through contact or observation methods. The innovative cap conveyor and rotation around the minor axis allow accurate and simultaneous measurement of trend and sag on any surface, including overhangs. Dimensions (closed): 3.

• Unique dual axis hollow hinge allows easy and intuitive measurements of any line or plane.

• The cap rotates 360˚ around both axes, allowing measurements to be taken on any surface, including overhangs. The cap can extend or create the measurement surface itself.

• The default compass orientation North makes this the only transit in the world that can measure strike and dip simultaneously. A simple rotation of the azimuth ring also allows simultaneous measurement of dive angle and dive direction, if preferred.

• A secondary axis of rotation and a cap conveyor allow simultaneous measurement of trend and dip.

• Hollow hinge / sight tube allows direct horizontal and vertical sight measurements.

• The hinge dial allows for tilt angle measurements and also serves as a versatile protractor.

• Excellent sighting and contact measurement capabilities.

• Long level double bubbles allow the user to level the compass from the sides and bottom.

• Flat bottom allows easier dive angle and dive azimuth measurements at low angles.

• The needle can be set to lock automatically, allowing accurate readings.

• Precision NdFeB disc magnet provides highly accurate readings and resists demagnetization.

• Our magnetic needle can be balanced for use almost anywhere in the world.

• Induction wetting makes for a fast-seating needle.

• A sapphire jewel bearing allows smooth needle movement throughout the life of the instrument.

• The needle lock button can lock or release the needle, depending on the model.

• Internal components are sealed with an O-ring to improve water and dust resistance.

• All transits are compatible with our Jacob's Staff / Tripod ball and socket adapter.

• Each model is available in Azimuth (0-360) or Quadrant (0-90) formats.

• Each comes with a protective leather case, perfect for taking your Brunton into the field.
