| Two Geographical Balancing Zones |
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, compasses must be balanced for different geographical zones in order to keep the needle in a horizontal position.
Previously, the globe was divided into five different balance zones in which specific compasses functioned. However, as people travel more and more, the need for a compass with a greater geographical range has increased. Thanks to Suunto's 'Two Zone System' there are only two balance zones to consider in compass use - the northern hemisphere and the southern hemisphere. In practice, this means that a Suunto compass designed for the northern hemisphere will still work for a fair distance into the southern hemisphere, and vice-versa.
Suunto also makes globally balanced compasses, which can be used accurately all over the world.
