Papua New Guinea DQY-1 Pro Geological Compass

This instrument utilizes a magnetic object—the magnetic needle—which has the property of indicating a specific direction along the magnetic meridian. Combined with readings from the graduated dial, it enables determination of the azimuth of a target relative to the magnetic meridian. By selecting two known survey points (or reference points), the position of an unknown target can be calculated. It can measure structural orientations, including strike, dip direction, and dip angle; conduct topographic surveys, including azimuth determination (i.e., intersection-based point positioning), slope-angle measurement, and horizontal-plane orientation; and measure vertical angles. The instrument features a compact design, small footprint, portability, reliable accuracy, and stable performance. An optional luminous scale has been added, allowing the scale to remain visible in low-light or dark conditions for several to over ten hours. Furthermore, the magnetic needle is mounted in a vertical configuration, which effectively reduces the time required for the needle to stabilize and thereby enhances measurement efficiency.
