Choosing the Mounting Location
WARNING: Do not install the Heading Sensor H2183 in a steel vessel (magnetic
hull). For a steel vessel, use Airmar’s model GH2183, combination GPS and
compass that can be mounted above the deck.
For accurate readings, selecting the best location for the sensor is very important.
It can be mounted on either a vertical or a horizontal surface. Choose a location
that balances the requirements below.
• Mount the Heading Sensor as close to the boat’s center of gravity as possible.
The lower it can be mounted, the more stable it will be, thus giving more
accurate compass readings.
• Mount near the center of the vessel’s fore-aft axis. This will give more accurate
pitch and roll readings. Avoid the areas near the bow and the stern.
• To prevent interference to the magnetic compass, mount the sensor 1.2m (4')
away from any structures or equipment that contains ferrous metals.
Do not install in a steel vessel (magnetic hull).
• To prevent interference to the magnetic compass, mount the sensor 1.2m (4')
away from anything that may create a magnetic field such as: magnetized
materials, electric motors, electronic equipment, power/ignition cables, and
batteries.
• Choose a surface with minimal vibration for more stable data.
• Mount reasonably level with the waterline for accurate pitch and roll readings.
• Be sure the cable(s) can be routed to reduce electrical interference from other
electrical wiring and any on-board equipment with strong magnetic fields such as
radar equipment, radio transmitters, boat engines, generators, etc. Separate the
cables by at least 1 m (3').
