Set Declination; Set Heading - Aqua Lung i750TC Owner's Manual

SET DECLINATION

Magnetic declination or variation measures the angle between the Earth's magnetic north and true north. The dec-
lination value for any region can be found on current geographical charts. By correcting for declination, you can
achieve a more accurate compass reading.
NOTE: Magnetic north changes over time; so use only current geographical charts to obtain the decli-
nation value for any geographical region.
