Weems & Plath C Plath Merkur SR - Hi Speed Compass, Type 4221

This U.S. Coast Guard approved Merkur SR High Speed nautical compass manufactured in Germany by C. Plath is the right compass for flush horizonal mounting on fast going craft. It is highly dampened so that it can withstand vibrational abuse that occurs at high speeds. The accuracy of indication- lag error- and oscillation period all exceed the International Organization of Standards norm. Additionally, the vibration resistance exceeds requirements of the German Hydrographic Institute. This outstanding compass features a full spherical construction with an internal gimbal system that accommodates all angles of heel without compromising accuracy. The oscillation-free double bottom compensates for volumetric changes. The black housing of the Merkur SR compass is seawater resistant and constructed of a light alloy with a glass dome that is insensitive to ultraviolet rays, and is guaranteed for life against cracking, crazing, and yellowing under normal use. No compass cover is required because of the glass dome construction.
