The Axis Quad Pocket Transit from Brunton is designed especially for easier geological measurements. Its innovative dual-axis, hollow hinge allows for intuitive, efficient, accurate measurements of planes, lines, bearings, and vertical angles.

Only one measurement configuration is needed for strike & dip, trend & plunge, and bearing and vertical angle, making your measurements more accurate and efficient. The innovative lid protractor and rotation around the minor axis enables accurate, simultaneous measurement of trend & plunge on any surface, including overhangs.

The axis employs a rare earth magnet on a sapphire jewel suspension and features an adjustable needle locking mechanism, high-visibility north and south markings, and induction damping for quick stabilization. The housing is hard anodized billet aluminum and is O-ring sealed to provide a waterproof performance.
