The meridian lines on a map indicate the direction toward true north while
your compass needle indicates the direction toward magnetic north. The
angle between these two directions is called magnetic declination.
You should check the magnetic declination for the dive site from a trusted
source, such as a recent map or the NOAA website. If the magnetic
declination is more than a few degrees, you must compensate for it when
navigating with a compass.
SIGHT A BEARING
A bearing is the angle between direction to north and the direction to a
target. This can be used in communicating directions with others or when
finding your location.
1. Hold the compass level with the sighting window facing you.
2. Align the target with the bearing line.
3. Read the bearing from the sighting window.
NOTE: Compensate for declination.
At the dive site, you should establish your general orientation by sighting
bearings of your underwater navigation aids, such as a shoreline or reef.
Memorize or make note of these bearings to use while diving.
MAINTAINING DIRECTION OF TRAVEL
With practice, you can maintain your direction of swimming over long
distances using your Suunto dive compass.
1. Find a visible target in the direction you want to travel.
2. Hold the compass level in front of you with sighting window facing
you.
3. Turn the bezel until the orienting indicators are aligned with the
triangle.
Swim towards target and check your direction when the target is not
visible by holding the compass as in step 2 above. If the orienting
indicators and triangle are not aligned, turn yourself until they are aligned
and continue travelling in the corrected direction.
Do not use the compass before you come to rest and can align the
