The M-3DL employs Suunto's two-zone system to help adventurers find their way anywhere in the northern hemisphere. Previously, most compasses functioned well in only one of five geographic zones. That's because the compasses were balanced differently based on the zone's inclination, i.e., the vertical intensity and direction of the Earth's magnetic field. However, as people began to travel more, it became clear that globe-hoppers needed compasses with a greater geographical range. Suunto's two-zone system, by contrast, considers only the northern and southern hemispheres. In practice, this means that a Suunto compass designed for the northern hemisphere--as the M-3DL is--will still work for a fair distance into the southern hemisphere and vice-versa. Suunto is one of only two compass manufacturers to offer two-zone compasses.
The M-3DL, which also features a jewel bearing and marking holes for drawing control points, measures 2.4 by 4.9 inches and weighs a mere 1.6 ounces. In addition, the compass carries a lifetime warranty.
