Why East and West is switched in Brunton compass?
Do you know why, for example, that E (east) and W (west) appear reversed on the compass above? The compass needle is still pointing toward the north but now it lines up with the E on the compass indicating that we’re facing east.
How is Brunton compass used to measure strike and dip?
Measuring Dip:
- AFTER you determine strike, rotate the compass 90°.
- Place the SIDE of the compass flat against the plane.
- Adjust the lever on the back of the compass until the air bubble in the “Clinometer level” is centered.
- Read the dip directly from the scale in the compass.
What is clinometer compass?
