E-Correction

Is used for correction of the ship´s asymmetrical weak iron field.
This compass binnacle does not include this corrector because according to regulations it should be installed in
the ship´s centre line where the influence does not occur. If it is necessary to move the compass binnacle to
port or starboard then the iron free zone has to be moved correspondingly to reduce the deflection.
