When interfacing this three-axis compass heading sensor to Garmin"s marine lineup of MFDs and radars, mariners can expect unparalleled radar overlay performance and accuracy along with excellent MARPA capabilities. This heading sensor (based on Airmar H2183) uses a rate gyro, so it can maintain an exceptional 2 deg heading accuracy under heavy dynamic conditions, with up to 30 deg of pitch and roll. In addition, it supports either NMEA 0183 or NMEA 2000 data output to fit any installation. Installation is a snap thanks to the heading sensor"s innovative design allowing it to mount to any angled bulkhead. Mariners can expect this heading sensor to provide trouble-free service in the harshest conditions and will learn to appreciate its reliability and excellent performance.
