MD71TMC TRANSMITTING MAGNETIC COMPASS SYSTEM
DESCRIPTION
The MD71TMC is a Transmitting Magnetic Compass (TMC) System which uses the latest technology to accurately process and convert the ship’s magnetic compass heading to NMEA 0183 heading data with unparalleled accuracy to one or more Heading Repeaters (Compass Repeaters) at any convenient location on a vessel.
Instead of using inflexible and bulky optical apparatus (reflectors, periscopes etc.) to view the magnetic compass, electronic remote displays may be used in the form of a Compass Repeater. TMC systems from Marine Data are simple and intuitive to use with quick and easy installation and on-board calibration.
