Whether you are offshore fishing or just enjoying family time on the water, feel confident and comfortable that the H2183 is your reliable source for heading information. The solid state, three-axis compass combined with Airmar’s additional advanced sensors and software provide unparalleled performance. What sets the H2183 apart from the competition is its ability to maintain 2 deg of heading accuracy under dynamic motion conditions such as steep heeling, hard turns and rough seas. Heading integrated with three-axis rate gyro and three-axis accelerometer data allows the H2183 maintain 2 deg of accuracy even if the vessel is pitching and rolling up to 30 deg. This level of accuracy is perfect for interfacing with autopilots, chart plotters and radar systems. The H2183’s innovative circular design easily mounts and aligns on ANY angled bulkhead. Designed for simultaneous use with NMEA 0183 and NMEA2000® devices, the Water-proof, easy to install sensor can be wired into both NMEA 0183 and NMEA2000® networks on the vessel with just a single cable.
