MAGNETIC SURVEY COMPASS

Description

Product Overview

A magnetic survey compass is a specialized geophysical instrument used for field surveys to measure the magnetic azimuth, inclination, and declination of a specific area. It is primarily utilized in geological exploration, forestry, navigation, and land surveying. Designed for precision and durability, these compasses provide accurate directional readings by detecting the Earth’s magnetic field.
