compass horizontally with the aid of a flat bottom, a glimpse of the surface,
your own bubbles going up, or the pull of gravity. In poor light or very
murky water, swing the compass slowly from right to left to ensure the
compass card moves freely before checking your bearing.
NAVIGATION AIDS UNDER WATER
The dip and stratification of rocks on the shore can often be followed over
large areas under water. Sand ripples may also form long lines parallel to
the shore that can be used for maintaining your direction of travel.
The direction of currents should be noted by their effect on algae or
drifting particles. Use the compass to check the bearing of the current.
Swimming in a straight line along the bottom is greatly facilitated if you
can line up three distinctive targets in your line of vision. As you reach the
first target, line up a new one farther away, so that you again have three
points determining your course. This way you can counteract the effect of
a side current.
In clear water, the compass can be used to swim in a search pattern over
a fairly large area. Count your swim kick pairs (each left or each right kick),
swimming on one of the cardinal directions (North, South, East, West).
Count up to 100 kick pairs (roughly 100 meters), turn 90 degrees, swim a
few kicks, then turn 90 degrees further, and again swim the same number
of kick pairs. Continue the pattern for as long as necessary.
The side displacement between each turn in a search pattern depends on
visibility. Keep the disatnce between each turn shorter than theoretically
possible.
CARE
Use only fresh water and mild soap for cleaning. Clean your compass after
each dive.
