Suunto A

Description

A compact high-accuracy compass for hiking and orienteering, the luminous bezel and markings make it ideal for navigating in poor visibility. Suunto A-Range – User Friendly Recreational Compasses The A-Range of recreational compasses is a series of handy, well designed, navigational aids which are assets in any environment. All four models in the series (A-10, A-30) are compact, high-accuracy instruments made from durable, clear, scratch resistant acrylic that have been ergonomically designed to fit into the palm of your hand for optimum ease of use. These light-weight compasses feature a fixed declination correction scale as well as a patent-pending lanyard snap-lock enabling the compass to be easily detached from the lanyard. Two Geographical Balancing Zones; The vertical intensity and direction of the earth's magnetic field, the inclination, influences the horizontal plane of a compass needle according to the latitude where it is used. Due to inclination, compasses must be balanced for different geographical zones in order to keep the needle in a horizontal position. Previously, the globe was divided into five different balance zones in which specific compasses functioned. However, as people travel more and more, the need for a compass with a greater geographical range has increased. Thanks to Suunto's 'Two Zone System' there are only two balance zones to consider in compass use – the northern hemisphere and the southern hemisphere. In practice, this means that a Suunto compass designed for the northern hemisphere will still work for a fair distance into the southern hemisphere, and vice-versa.
