Thanks Paul

Are you referring to the fluxgate compass for the autopilot? Mine is located in the aft cabin on the port side inside the locker with the 2 sliding doors. It is located inside that locker at the end as far to the bow as you can get.

Hi Thanks for the info but still not able to find it on either positiondde0f
It can be anywhere near the boat centreline. Mine was installed by the dealer, Swan's in the stbd settee in the cabin.

At the stern end of the Starboard settee, just in forward of the sink. I found out that is a not a good place for the tool box!!!!

Trace the cable

On my boat it is installed on the bulkhead facing aft toward the rudder quadrant. The reason you have received multiple answers is that when the fluxgate is installed it needs to be where there is no magnetic interference and should be as close to the centerline of the boat.

A better way to find it would be to find your computer (that gray thing about 12" x 12"). If you look on the connections on the bottom one will be labelled compass. Follow that wire out.

Mine can be seen on the starboard side of the cockpit as you walk through the transom. Below where the removable seat is.

Forward portion of port settee. When I upgrade the autopilot to the one a dock neighbor gave me I will make it a little more center though. It is always a few degrees off from the ships compass.

Found it in the starboard settee bow end, just where I recently decided to store the space heater problem solved I think

Thanks to all
Cheers p

Ideally you want that sensor near the pitch and roll center of your boat. Of course that's often right where it's most difficult to mount it and route the wiring!
And then there's the need to stay clear of steel tools, supplies, spare parts, and permanent magnets in other pump motors, for instance.

Sidebar: We really wanted... to mount it on the base of the table in the center of the cabin, but it ended up nearby on the inside of the frp module that supports our nav station.

IF.... a prior owner or some heedless factory dude put yours way back aft or any other place that makes its sensing task more difficult, you should have a go a relocating it. Note that it has to correctly oriented side to side when mounted, too.

If that sensor is out of sight, also put their little "no magnets" warning sticker on the nearest surface facing you.

The closer it is to its optimal location, the easier it will be to calibrate it and more reliable it will be when the boat gets moved around by rambunctious wave action...
