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...

I took Craig's question differently, however: Before even starting to
develop a deviation table for a compass, a good compass adjustor first
tries to minimize the compass's deviation though use of the compensating
magnets within the compass and even external devices such as quadrential
balls and Flinders sticks (the latter two are used mostly on steel vessels
since, as one might imagine, it's quite difficult to get a compass to read
correctly when surrounded by a big lump of iron). 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?
