We offer Brunton Compass (Geological Compass) which is available in a leather or wooden case. This compass differs from modern compasses, as it utilizes magnetic induction damping rather than fluid to dampen needle oscillation. It is widely used by geologists and surveyors to make accurate degree and angle.
