The Lilley & Gillie NMEA Course Magnetic Heading Repeater is a high-accuracy digital heading indicator designed by John Lilley & Gillie Ltd. to display real-time vessel heading on the bridge. Specially engineered for integration with Transmit Magnetic Compass (TMC) systems (such as the Lilley & Gillie GS820) or gyrocompass networks, this repeater converts incoming digital NMEA serial data into a continuous, highly readable visual heading reference.

Designed for wheelhouse consoles, chart tables, and overhead navigation panels, the repeater allows watchkeepers and helmsmen to monitor magnetic or gyro heading at a glance. Featuring smooth card movement, adjustable night-vision dimming controls, and wide NMEA 0183 protocol compatibility, it provides an exceptional heading display solution for commercial merchant ships, workboats, and ocean-going vessels.

Key Features:
• Direct TMC & Gyro Integration: Processes serial heading data directly from magnetic compass TMC pick-offs, fluxgate units, or gyrocompasses.
• Flexible NMEA 0183 Input: Compatible with standard IEC 61162-1 heading sentences ($HCHDG, $HCHDT, $HEHDT, $THS).
• High-Visibility Display: Clear, high-contrast compass dial with fine degree division markings for instant steering verification.
• Integrated Night Backlighting: Features variable dimmer control for low-glare operation during night watches.
• Low Power Consumption: Efficient solid-state electronics designed for 24V DC shipboard power networks.
• Compact Panel Design: Space-saving footprint allows easy flush installation into crowded navigation bridge consoles.
