Whether you are offshore shing or just
enjoying family time on the water, feel
condent 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° 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.
• Better than 1° static heading accuracy
• Best-in-class 2° heading accuracy in dynamic
conditions
• Three-axis solid-state compass
• Three-axis accelerometer for pitch and roll
• Three-axis rate gyro provides rate-of-turn
data and improves heading accuracy in
dynamic conditions
• Only recreational heading sensor that
uses a three-axis rate gyro
• Easily mounts on any angled bulkhead
• IPX6 waterproof enclosure
• Default 10 Hz update rate for heading
• Outputs NMEA 0183 and NMEA 2000 data
simultaneously
