USER GUIDE

The high-quality, liquid-lled Suunto diving compasses are
durable, reliable and easy to use. The Suunto diving compass
range includes both wrist and combo models. The SK-7
compasses have a side reading window.

The direction line, which indicates the direction of your destina­tion, is indicated as follows:

COMPASS USE FOR DIVERS

ABOVE WATER

- Sighting a compass bearing

Hold the compass so that the compass is in a horizontal
position and the direction line points away from you. Turn with
the compass until the direction line points at your destination,
then turn the direction ring until the magnetic North needle is
aligned between the direction slit marks. On the SK-7 compass

5

the front end of the direction line shows your compass bearing,
and as long as the North needle is aligned between the slit
marks, the direction line points toward your destination. You
can also take a bearing by directing the compass towards the
destination and by reading the compass bearing from the side
window. This bearing can be memorized by turning the direc­tion ring to that bearing.

- Obtaining a bearing from a map

Place the compass on the map, the direction line pointing from
your point of departure to your destination. If necessary, use a
ruler to connect the two points, and hold the compass against
the ruler. Turn the direction ring until the direction slit marks
point to the magnetic North on the map. When proceeding from
map to terrain, all you have to do is keep the North needle
between the slit marks while going from point of departure to
destination.

- Setting a given bearing or direction

The scale division is 360 degrees going clockwise from 0
degrees at North. Turn the direction ring until the front end of
the direction line is at the desired direction. Turn the compass
until the needle falls between the slit marks. The direction line
now points in the desired direction.

- Magnetic declination

Maps are drawn in correlation to the geographic poles, while
the magnetic compass needle is subject to magnetic declina-

6

tion, which varies according to the location. For absolutely
exact map work, local declination (which is usually given on the
map) should be taken into account.

- General orientation on the diving site

Before diving, check the main compass bearings at the diving
site, paying special attention to memorizing the direction
of the shoreline and bearings of landmarks that may be of
importance.

UNDER WATER

Natural aids to underwater navigation

- The underwater extension of the shore’s inclination tells
the diver if he is following the shoreline. Be extremely
careful, however: underwater ridges may lead you
astray. Surface occasionally to check.

- The dip and stratication of rocks on the shore can often
be followed over large areas under water.

- Sand ripples form long lines parallel to the shore.

- 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).

- In shallow water, the sun’s direction can be seen from
shadows on the bottom, or by looking toward the
surface.

- Swimming in a straight line along the bottom is greatly
facilitated if you can line up three distinctive objects in

7

your line of vision. As you reach the rst one, 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.

Using the compass under water

- Usually, a compass must be held precisely in a
horizontal position, otherwise the magnetic needle will
stick. However, in the SK-7 the allowed inclination is
approximately ±30 degrees.

- Do not attempt to use the compass before you come
to rest and can align the compass horizontally with the
aid of a at bottom, a glimpse of the surface, your own
bubbles going up, or the pull of gravity. When doubtful,
as in darkness or very murky water, turn the compass
slowly right and left, checking that the North needle
swings freely, before trusting your bearing.

- Swimming along the bottom, make use of xed points.
Keep still until the needle settles between the slit marks
(your predetermined bearing), choose a distinctive object
near the edge of vision in that direction, swim toward it,
and repeat the operation on reaching it.

- Commonly, the diver wants to follow a predetermined
bearing under water, trying to reach a wreck, a rock etc.
When submerging after obtaining the bearing on the sur­face, he must be careful not to accidentally disturb the
direction ring, and to be on the safe side, the compass
bearing should always be memorized.

- Avoid swimming long distances “in the blue”. With
practice you can swim straight by holding the compass
constantly in front of your face, making sure that the
direction line as precisely as possible points in your
swimming direction. This can be facilitated by holding
the compass in your hand instead of attaching it to your
wrist. When possible, start by diving straight down to the
bottom, then use the compass to follow xed points, as
described above.

- 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 main bearings (North, South, East, West). Count
to 100 kick pairs (roughly 100 meters), turn 90 degrees,
swim a few kicks, then turn 90 degrees further, and
again swim 100 kick pairs. The pattern is continued for
as long as necessary. The side displacement between
the long legs in a search pattern depends on visibility.
Make it preferably shorter than theoretically possible, as
your directional error on the long legs is apt to be in the
order of several degrees.
