Heading Repeater with 118mm compass dial display, with rotary control. Enclosed in a compact, powder coated aluminium casing.

The MD77HRB is a NMEA-based Compact Heading Repeater with a clear, easy to read analogue dial display of heading data. The 118mm diameter dial is graduated in 1 degree increments. The MD77HRB is housed in a robust, compact aluminium enclosure fitted with a rotary encoder for controlling the level of background illumination.

When multiple heading sources are available in the heading data (e.g. True and Magnetic) the MD77HRB automatically prioritises and indicates which heading source is in current use. The encoder has a pushbutton facility for an internal self-test.
