Compass Linearisation
Compass linearisation corrects (compensates) the active compass for
deviation caused by large iron masses (for example, the engine, keel,
fittings made of ferrous metals and other electrical equipment).
To linearise the compass you must turn your vessel in slow circles until
sufficient information has been logged to provide deviation data.
Procedure
1. At the deviation display, press the right-hand key to start the
linearisation procedure (the display now says ‘TURN BOAT
SLOWLY’).
