It includes a sighting mirror with a quick-reference lid for improved bearing readings, along with a tool-free declination adjustment system for aligning magnetic north with true north. The compass integrates a triple clinometer system for measuring slope and vertical angles, a bubble level for stability, and a magnified readout for improved accuracy. Its luminescent components enable low-light navigation, while the durable baseplate features rulers, map scales, and a removable protective foot that stores reference cards with conversion data. Built for reliability in rugged, wet, and dirty conditions, it supports advanced map work and field navigation for outdoor, technical, and professional use.
