The real star of the MC-2G, however, is its global needle, which works anywhere on the planet. 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 responded by developing two-zone systems--which work in either the northern or southern hemisphere--and one-zone systems such as the global MC-2G. Now there's no need to purchase several compasses before embarking on your around-the-world eco adventure.

The MC-2G, which also sports a red nylon lanyard for around-the-neck use, measures 2.5 by 0.6 by 3.9 inches (W x H x D) with the lid closed and weighs a mere 2.65 ounces. It's also backed by a lifetime warranty.
