I will second that opinion. I diliberately installed my fluxgate backwards so that I could place it in a safer and better location. When I took the boat out to swing the compass I corrected for 180 degrees to compensate. Now if someone were to reset the controls to default or factory settings it would be off by 180 degrees. Then I would have to do the swing compass procedure all over again.
