About the compass
Compasses mechanical have been used for thousands of years.

BALANCING OF COMPASSES
Bipolar System
The intensity and the direction of the magnetic field of the earth vary according to the degree of latitude in which we find ourselves and influence in the vertical plane, or tilt, of the needle of the compass. Due to the inclination, compasses must be balanced for the different areas in order to maintain the needle in a horizontal position.
Compasses Suunto had been balanced for five geographical areas. But now, people travel more and grow the need of the use of a compass balanced for a wider area. Thanks to the 'Bipolar System' developed by Suunto compasses have been balanced to operate in two geographical areas - the North and the South. In other words, a compass designed to work in the Northern hemisphere will be able to work up to a certain point in the Southern hemisphere, and vice versa.
