5.4.3 CALIBRATION
The variation table is used to match magnetic value readout on the chartplotter
comparable with the value given by the compass of the boat. In other words, since
the compass of the boat must be compensated (due to the iron masses, ...), we use the
same values given by the chartplotter. This means that, for example, if the BRG to
the next Waypoint readout in the chartplotter display is "X" Mag degree, if you steer
the boat reading "X" Mag degree from the compass, you are driving well toward the
next Waypoint.
