Back in the day, users had to purchase a compass balanced for one of 5 different zones. A Suunto Compass is balanced based on only the northern and southern hemispheres. This means that Suunto compasses balanced for the northern hemisphere also provide accurate readings in many northern parts of the southern hemisphere. Suunto A-Series Compasses are designed for the northern hemisphere. If you are traveling very far south into the southern hemisphere, you may want to look for a compass balanced to that location.

The A-Range compasses also have a fixed declination correction scale. This means that you cannot change the declination. For instance, in Minnesota it would read at about 4 degrees, but if you go to Alaska it's about 17 degrees. So in Alaska you'd have to do the math to get the difference. In an adjustable declination it can be changed as you travel to different regions.
