BMC-2 MIRROR COMPASS This mirror compass has many features that make it outstanding in its class. The gear-operated declination adjustment system is a standard feature that makes this compass excellent in areas with large magnetic variations. Another standard feature is the clinometer which can be used to measure terrain slopes, heights, free space over obstacles when assembling a CCTV-antenna, etc. The bezel is available with azimuth (0-360°) or quadrant (0°-90° – 0° – 90°) graduations with two-degree intervals. Parallax error can be eliminated by means of the clever arrangement of luminous points and color lines. MC-2 mirror compass is compact, robust, anatomically designed, and includes a lanyard equipped with a sliding lock.
