Choosing the Mounting Location
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 sensor as close to the vehicle/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 vehicle/boat’s fore-aft axis. This will give more
accurate pitch and roll readings. Avoid the areas near the front/bow and the
rear/stern.
• To prevent interference to the internal magnetic compass, mount the sensor:
- A minimum of 0.3m (1') from other standard and steering compasses.
- Away from any structures or equipment that contains ferrous metals.
- Away from anything that may create a magnetic field such as: magnetized
materials, electric motors, electronic equipment, engines, generators, power/
ignition cables, and batteries. For distances, follow the respective
manufacturer’s recommendations.
- Do not install within a steel vehicle/boat (magnetic material).
• Choose a surface with minimal vibration for more stable data.
• Mount reasonably level (with the waterline on a boat) for accurate pitch and roll
readings.
