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.
