The MD68HRB from MARINE DATA is a dual-scale NMEA-based Steering Repeater with a clear and easy to read analogue dualscale
dial display. The display has an outer dial of 164 mm diameter graduated in 1 degree increments and an inner dial of 103 mm
with a resolution of one tenth of a degree. The MD68HRB is housed in a robust, compact aluminium enclosure fitted with a rotary
encoder for controlling the level of background illumination. Finished in jet black to complement other marine navigation equipment,
it is ideal for any vessel.
When multiple heading sources are available in the heading data (e.g. True and Magnetic) the MD68HRB automatically prioritises
and indicates which heading source is in current use. The encoder has a pushbutton facility for an internal self-test.
Compact and rugged, the MD68HRB offers a steering repeater solution for digital heading data (ship’s heading) to be conveniently
displayed and monitored at any convenient location on a vessel. Suitable where the available space is limited and may be either
bulkhead or panel mounted.
The MD68HRB from MARINE DATA: Flexible in application, easy to install and simple to maintain.
