Sailaway...fluxgates are easily "deviated" by metal objects.
They can be compensated for deviation (and local variation in some cases) by the calibration process which involves sailing in a circle. But NEW metal objects put close the the fluxgate or any magnetic material and make them just as unreliable as a standard compass in similar circumstances.

A great article that is just a little dated on the various compass systems can be found at:
