In order to get an accurate compass-heading reading from a compass, the magnetic needle in the compass, must be able to move freely inside the compass capsule.  The needle must be balanced to make sure it can move freely, without touching and dragging along the top or bottom of the capsule; while consistently and precisely point to a compass-heading.

A Compass Is Not a Toy!  However Many Compasses Being Sold To Consumers Are Simple Low-Grade Toy-Class Items, Made To Produce A Quick Impulse Sale, And Profits.  These Should Never Be Used For Navigation!

Because horizontal and vertical magnetic pull from the earth's magnetic field varies considerably in different locations around the world, a compass needle that balances perfect in North America will drag or stick in the capsule when in South America.

Quality compass instrument manufacturers have developed their own needle-balance zones To Make Compasses For Use In Specific Hemispheres Around The Globe.  When Using A Compass, Know What Part Of The World The Compass Is Balanced And Tuned For.  Always Navigate With a Precision Compass and One That You Know For a Fact Is Balanced For The Area That The Compass Will Be Used!  The Compass Was Balanced For!   What Most Compass Makers Balanced Their Compass Needles For One Of 5-Zones as shown in the image below.

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 by Suunto Engineers, in which compasses were balance to function in accurately.   However, as people travel more and more, the need for a compass with a greater geographical range has increased.  Now, 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.   Currently, Suunto is one of only two compass manufacturers to offer two-zone compasses.
