Field compasses in general

Mechanical compasses have been used for navigation for well over a thousand years.

Still today magnetic compasses are environmentally friendly, economical and the most reliable navigaiontal aid when out in the bush. The oldest Suunto field compasses, which are still in use, were manufactured in 1938. A high quality field compass hardly needs any other service than washing in fresh water from time to time. The compass works without any external power supply. The compass gets its power from nature – from the magnetic north pole.

Global Balancing System

The vertical intensity and direction of the earth's magnetic field, the inclination, influences the horizontal plane of a compass needle according to the latitude where it is used. Due to inclination, many compasses must be balanced for different geographical zones in order to keep the needle in a horizontal position. The Suunto M-3 however incorporates a Globally Balanced Needle that works accurately across the globe.
