Large Dual Scale Steering Repeater Display (MD68HR)

Large Dual Scale Steering Repeater Display (MD68HR)

Large Dual Scale Steering Repeater Display (MD68HR) is a dual-scale NMEA-based Steering Repeater. Digital heading data (ship’s reading) may be displayed and monitored at any location on a vessel. The inner dial has a resolution of one tenth of a degree.

When multiple heading sources are available in the heading data (e.g. True and Magnetic), the MD68HR allows the user to select the heading source and indicates which heading source is in current use.

This Large Dual Scale Steering Repeater Display is compact and rugged and offers a heading repeater solution for locations where the available space is limited and may be either bulkhead or panel mounted. It is finished in jet black to complement other marine navigation equipment.

The MD68HR Steering Repeater from MARINE DATA: flexible in application, easy to install and simple to maintain.
