The elite Arrow 30 compass is designed to be read clearly and quickly, making it a great choice for competitive navigation. The lightweight compass features a fast and wide plastic needle that responds nimbly to changing conditions, letting adventurers take fast readings while on the move. The unit is also covered in durable, water-resistant printing that holds up to rainstorms and other weather hazards. Add in an ergonomic shape, dual and jewel bearings, twin magnets, a magnifying lens, and marking holes for drawing control points and you have a great compass for a host of specialized sports.
The Arrow 30 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 Arrow 30 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 Arrow 30 measures 2.2 by 4.3 inches and weighs a mere 1.1 ounces. It's also backed by a lifetime warranty.
