The MD67HR is a weatherproof, IPX6-rated, NMEA-based heading repeater for external use. Digital heading data (ship’s heading) may be conveniently displayed at any location on a vessel. The MD67HR has a tough polycarbonate faceplate which is user-replaceable and a rotary encoder for varying the background illumination.
Compact and rugged, the MD67HR offers a heading repeater solution for locations where the available space is limited and may be either bulkhead or panel mounted. Finished in jet black to complement other marine navigation equipment. Equipped with LED indicators and automatically displays the heading source in use (True or Magnetic). The MD67HR from Marine Data: flexible in application, easy to install and simple to maintain.
