SteadyCast heading sensor is a simple, easy-to-install solution that provides fast calibration and premium heading accuracy. It aligns your boat bow to its actual orientation so you know where you are casting according to your chartplotter screen. Its heading output rate at 10 Hz and accuracy of plus or minus 3 degrees ensures your chart orientation and boat heading line match up with reality, even at trolling speeds or when dead in the water. You can also be confident your heading information will remain accurate, even in rough water. SteadyCast heading sensor installs easily with NMEA 2000 plug-and-play interface and a simple 2-step precision calibration process for compatible Garmin chartplotters.
