Instead of monitoring information from several sources, Suunto D9 provides you with all the crucial information from a single source, conveniently mounted on your wrist. The integrated digital compass can be accessed from both DIVE and TIME modes, and provides a graphical compass rose display and numerically displayed bearings. Bearings can be locked, and visual aids are provided for navigating set courses or for pattern navigation. Headings can be stored in the memory for later analysis using the memory functions or the PC interface.
