On my boat the installer of the fluxgate compasses spent quite some time looking for places in the boat which were as far away from metal as possible in which to install them, but no extra compensating magnets were used. Of course my boat was fiberglass hulled so it was not too big of a problem...

Is this sort of compensation also done for fluxgate compasses? Is it the same as or different from the way it is done for traditional compasses?
