2 Installation

Note: Because the compass is electronically aligned after installation

(see Chapter 3: Calibration), you can mount it so it faces in any direction.

Figure 2-2: Compass - recommended location for non-steel hulls

Finding the most suitable location

To identify the best compass location on your boat, start at the pitch and

roll center then move the compass up and/or aft until you find a location

with minimal magnetic disturbance.

To check if the intended mounting location is free from magnetic

influence:

1. Temporarily fix a simple handheld compass at the intended location.

2. Turn the boat through 360°, watching for any differences between the

hand bearing compass and the boat’s main steering compass.

3. The site is suitable for the fluxgate compass if the differences are less

than 10° on all headings.

Location on steel-hulled boats

On steel-hulled boats you must mount the compass at least 1 m (3 ft)

above the main deck or wheelhouse. If mounted below deck, the compass

will not work correctly as the hull shields the Earth’s magnetic field.
