• In shallow water, the sun’s direction can be seen from shadows on the bottom, or by looking
towards the surface
• Swimming in a straight line along the bottom is greatly facilitated if you can line up three
distinctive objects in your line of vision. As you reach the fi rst one, line up a new one farther
away, so that you again have three points determining your course. This way you can coun-
teract the effects of side current.
Compass Balancing
The horizontal and vertical components of earth’s magnetic fi eld vary considerably in different
locations. For this reason Suunto compasses are balanced for 5 different zones. If the compass
is used in an adjacent balancing zone the compass needle will tilt only slightly. However, the
farther the compass is used from it’s intended zone, the more the needle will tilt. In extreme
situations the needle might stick. For this reason it is very important to know in which country
the compass will be used.
