This C. Plath Merkur SR Compass can be mounted in many configurations with the optional mounting bracket (73 115) or horizontal flush surface mounting. It is manufactured in Germany by C. Plath and features a full spherical construction with an internal gimbal system, which accommodates all angles of heel without compromising accuracy. The oscillation-free double bottom compensates for volumetric changes. The black housing is seawater resistant and made of a light alloy. The super-strong glass dome is insensitive to ultraviolet rays and is guaranteed for life against cracking, crazing, and yellowing under normal use. The accuracy of indication, lag error, and oscillation period all exceed the International Organization of Standards norm. Additionally, the vibration resistance exceeds requirements of BSH (German Hydrographic Institute). This compass is U.S. Coast approved for lifeboat use with a registered NSN number.
