The Brunton compass, while over 100 years old, is still the primary tool for generating geologic field data. There are several key components of the compass, including the sighting arm, magnetic needle, clinometer, index pin, and bubble and clinometer levels..
A Brunton Compass is a highly accurate sighting compass/transit with a built-in Clinometer for measuring Strike and Dip angles or for measuring the inclination of a slope or to find angles to calculate heights/distances using Trigonometry. A Clinometer is just the part that measures angles without the compass portion
