Suunto has been manufacturing compasses since the 1930's and is the world's foremost authority on compass design and manufacturing. The high-quality liquid filled Suunto SK-8 has set a new standard for dive compasses. The device features 2-3 times larger tilt potential than in conventional diving compasses and provides easy-to-read numerals. The SK-8 has been improved for faster stabilization and enhanced readability. Both northern and southern hemisphere models can be used over a wider area of the globe thanks to an upgraded magnet. By adding the SK-8 compass to different Suunto Combo consoles, you can create a personal console that meets your specific needs. For example, CB-Double can be made by adding the SK-8/DS compass to the reverse side of the CB-One. Or you can configure your CB-One console to a CB-Two by adding an SK-8 compass on top. If you add the SK-8/DS compass on to the reverse side of the CB-Two In Line, you get a CB-Double in Line. And CB-Three In Line console is made by adding a SK-8 compass on top of a Two In Line console. Compass Balancing 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. Available in a variety of configurations
