ComNav Commander P2 Installation & Operation

Fluxgate Compass

PN 20320004
Specifically designed for ComNav autopilots, the ComNav Fluxgate Compass directly senses
the Earth's magnetic field. The unit incorporates a heeling coil for better performance when
the vessel is either rolling or heeled. The Fluxgate Compass is a sealed, waterproof unit
which may be mounted on a deck, shelf, or bulkhead. This compass outputs the traditional
analog compass signals – Sine & Cosine signals. It is supplied with a 12 metre (40') cable;
an adapter cable (PN311100024) is required to wire it into the Commander P2's SPU.

Magnetic Compass Sensor

PN 20320002
The ComNav Magnetic Compass Sensor detects the position of the compass card of an
externally gimballed magnetic compass. The sealed unit can be attached to the bottom of
any of ComNav's Magnetic Compasses, or the bottom or top of many other brands of
externally gimballed magnetic compasses. It is wired directly to the SPU, with the attached
25' cable.
