The superior SK-7 has an exceptional tilt potential of +/-30 degrees, which is 2 or 3 times larger than in conventional diving compasses. The firm-grip bezel with a ratchet at every fifth degree is specially designed to prevent sand and dirt contamination, allowing smooth turning in all conditions. The compass is available in wrist, console, and hose-mounted models.
The SK-7 can also be fitted on the Suunto Cobra dive computer. It has easy-to-read numerals on a phosphorescent compass card and a large side-reading window.
By adding the SK-7 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-7/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-7 compass on top. If you add the SK-7/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-7 compass on top of a Two In Line console.
The horizontal and vertical components of the earth's magnetic field vary considerably in different locations. For this reason Suunto compasses are balanced for 5 different zones. If the compass is used in an adjacent balancing zone, many compass pointers will tilt only slightly. However, the farther a compass is used from its correct zone, the more its pointer tilts. In extreme cases, the pointer will stick. For this reason, it is extremely important to know in which country a compass will be used.
