MD67RDI Weatherproof Dial Rudder Angle Indicator

The MD67RDI from MARINE DATA is a weatherproof, IPX6-rated, NMEA-based Rudder Angle Indicator.

The MD67RDI is a weatherproof, IPX6-rated, NMEA-based Rudder Angle Indicator. It provides a clear and easy to read 120 mm diameter analogue display graduated in 1° increments from 45° Port to 45° Starboard. Housed in a robust, compact aluminium enclosure for external or internal use, it is ideal for any vessel.

The MD67RDI has a tough polycarbonate faceplate which is user-replaceable and a rotary encoder control for varying the background and pointer illumination.

Compact and rugged, the MD67RDI offers a Rudder Angle Indication 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.

The MD67RDI from Marine Data: flexible in application, easy to install and simple to maintain.
