However, Suunto has developed a patented Global Needle that will perform perfectly with needle tilts of up to 20 degrees.  This allows a single compass to be used effectively in all 5 of the earth's zones (see below).  So when we say that a compass is outfitted with a Global Needle for true world-wide performance, now you know what we mean.

But, what if you're not a world traveler? Why would you want a global needle? Well, the global needle's unique ability to handle tilts up to 20 degrees makes it perfect for hikers that don't want to break their stride. Not having to level the compass exactly makes it easier to take an accurate reading while you're still moving along the trail.

A special thank you to Suunto for the use of the zone chart, above.
