Professional mirror Compass. The advanced navigation Compass. When venturing out into new territory, these sighting compasses offer precision navigation with a variety of carefully engineered and dependable features for challenging conditions. 2.56 x 3.98 x .71 inch.Hailing from Suunto’s MC range of mirror compasses, the MC-2DLIN is an invaluable tool for people who value highly accurate and reliable directional measurements, such as surveyors, miners, architects, rescue patrols, hikers, boaters, and the military. The MC-2DLIN boasts a fixed declination adjustment system–standard throughout the range–that’s especially useful when working in areas with large magnetic variation. The tool’s additional sighting hole, meanwhile, ensures superior accuracy, as does the jewel bearing. Add in a mirrored lid, a baseplate with rubber nonslip feet, a clinometer that measures the ground slope, luminous points, and an easy-to-read bezel with self-cleaning bearings and you have a versatile, practical compass for a variety of applications.

The MC-2DLIN employs Suunto’s two-zone system to achieve precise, accurate readings regardless of location. 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-hopping adventurers 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 MC-2DLIN 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 MC-2DLIN, which also sports a 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.
