Fluxgate Compass
Important! Always keep in mind that the compass is the single most vital part of an
autopilot system. Locating a Fluxgate Compass properly, particularly on
steel-hulled boats, is essential to ensure proper operation of the autopilot.
For best performance, the Fluxgate Compass must be mounted parallel to, and as close as
possible to, the boat’s fore-aft centreline, and also as close as possible to the boat’s centre of
pitch and roll. This is typically low in the boat, at or about the waterline, and slightly aft of the
centre of the boat.
You must keep the compass as far away as possible – at least 2 metres (about 6’) – from
engines, electric motors, and other magnetic objects.
The compass must be mounted with the correct side up (that is, with the cable coming out of
the top of the unit). The arrow labelled BOW should point forward.
Holes are provided in the case to attach the Fluxgate Compass either to a bulkhead, or to a
horizontal shelf or deck.
