Suunto Combo [8/12] Compass balancing

• 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.
