Transmitting Magnetic Compass

Manufacturer: Red Line Instruments

This modification converts a conventional gimballed magnetic compass into a Transmitting Magnetic Compass (TMC).  The TMC pickup coil is attached to the underside of a externally gimballed compass and terminated in a small sealed interface box mounted near the compass.  The coil generates a NMEA0183 sentence and can be directly connected to suitable equipment without the need for additional equipment.  The assembly is factory assembled and aligned to ensure it's accuracy.  The NMEA sentence is mapped to the compass card.

Red Line Instruments modify the Autonautic compasses models CHH and C20. Once the NMEA Pickup is installed the compass readout is mapped to the NMEA $HCHDG sentence.  

Other gimballed compasses can be modified - please enquire.

Pricing depends on the compass to which the TMC pickup is fitted, please enquire for pricing and availability
