DQL100-G1J Mine Suspension Compass

Product Overview

This instrument is primarily used for measuring magnetic azimuths and dip angles along guide lines established with a compass in secondary roadways of mining areas and on longwall faces. Thanks to the addition of a laser collimation device, measurements can be extended by means of beam projection. The DQL100-G1J mine laser suspended compass consists of the DQL100-G1 mine suspended compass equipped with an FD-1J laser mount. This design eliminates the accuracy limitations inherent in traditional suspended compasses, which rely on visual sighting by operators to determine azimuths. Moreover, when conducting surveys in high-risk environments such as mine shafts, crosscuts, and stopes, the laser can replace the suspension cord, thereby enhancing operator safety and improving work efficiency.
