Airmar H2183 Compass
Sensor Connector Supplied
Cables Sold/Fabricated Separately

Airmar Transducers
H2183 Heading Sensor

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° of heading accuracy under dynamic motion conditions, such as steep heeling, hard turns, and rough seas. Heading integrated with the three-axis rate gyro and three-axis accelerometer data allows the H2183 to maintain 2° of accuracy even if the vessel is pitching and rolling up to 30°. 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 NMEA 2000® devices, the waterproof, easy-to-install sensor comes with a single cable which can be wired into both NMEA 0183 and NMEA 2000 networks on the vessel.
