4.1 Select the location

The compass is primarily designed for mounting below deck on a bulkhead. On steel-hulled boats you must mount it above deck.

Standard location

To achieve the best performance from the compass, mount it:

•as near as possible to the boat’s pitch and roll center to minimize compass disturbance

•at least 0.8 m (2 ft 6 in) away from the boat’s steering compass to prevent deviation of either compass

•away from the front third of the boat (otherwise shock motion will affect compass performance)

•away from potential sources of magnetic interference, such as: motors, drive units, loudspeakers, alternators/starters, electric cables, large ferrous objects (such as engines, ballast, keel, gas bottles and tool boxes)

Note: Because you align the compass after installation (see the control unit handbook), you can mount it so it faces in any direction.
