Surveyor's Compass

A Surveyor's Compass is a surveying instrument used to determine horizontal angles and bearings. It typically features a magnetic needle that aligns with the Earth's magnetic field, providing directional reference points. Surveyors use it to measure angles between landmarks, helping to create accurate maps and layouts for construction and land division. The device consists of a circular dial, a sighting telescope, and sometimes a leveling bubble to ensure accuracy. Overall, the Surveyor's Compass is essential for land surveying, enabling professionals to gather precise geographical data.
