MD69BC Bearing Circle Sight for Bearing Compass RepeaterOVERVIEW

The MD69BC is a traditional vane type Bearing Circle, which allows an observer to take a compass bearing by aligning the two sighting vanes with a distant object. The near vane contains a peep sight, while the far vane contains a vertical sighting wire. A diametric horizontal wire from the near vane to the far vane lets the observer read the bearing from the Compass Repeater card.

A reflector vane positioned behind the far vane allows the observer to observe azimuths of luminous celestial bodies (stars and planets) at various altitudes by picking up their reflection in the black mirror. When the body is observed, its reflection appears behind the vertical wire in the far vane. The MD69BC is supplied with a removable shadow pin, which indicates the sun’s azimuth by the direction of its shadow.

The instrument is finished in Jet Black (RAL9005) Fine-texture Powder Coat to complement other external marine navigation equipment and is supplied in a wooden instrument box.

The MD69BC Bearing Circle from Marine Data is flexible in application and easy to use and maintain.
