5.4.3 CALIBRATION
The variation table is used to match magnetic value readout on the chart plotter
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 chart plotter. This means that, for example, if the BRG to the next
Waypoint readout in the chart plotter 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.
