Autonnic A5501 + A4032 bundle
Shows heading on a moving compass card
Autonnic A4032 Compass Pick Up included 
Clear ‘at a glance’ analogue display 
Straightforward DIY installation 
 
The A4032 Autonnic Compass Pick Up Sensor takes magnetic data generated by an existing Marine Compass and converts it into NMEA0183 data to use with the included Moving Card Compass Indicator.
 
The TMC Sensor avoids the need to install a standalone compass unit minimising cost and system complexity while maintaing the precision of the magnetic compass. Its roots are found in larger vessels where the ship’s compass is precisely calibrated and for certification purposes acts as the reference point for all navigation systems.
