Suunto D9 with titanium strap

Suunto D9 is a highly advanced all-in-one dive computer. It combines all dive-critical information – such as depth, time, tank pressure, decompression status and direction – in one instrument, conveniently mounted on your wrist.

Digital navigation
Suunto D9 displays a graphical representation of a compass rose. The rose displays the cardinal and half cardinal points, and the current bearing is also displayed numerically. A bearing can be locked to help you follow a selected course, and directional arrows point towards the locked bearing.

Multi-mode versatility
Suunto D9 has three dive modes. The Air mode is used for diving with standard air, the Nitrox mode for up to three nitrox mixes, and the Gauge mode for use as a bottom timer.

When in Nitrox mode, you can accelerate decompression by switching to a gas mix with a higher oxygen percentage. You can preset three different gas mixes (with between 21% and 99% oxygen) and set PO2 values for each individual gas. While diving, it's quick and easy to switch between enabled gas mixes.

In the Gauge mode, Suunto D9 works as a bottom timer and also provides accurate profile sampling and bookmarking functions. A dive timer with a reset function displays the dive time in minutes and seconds. This is extremely useful for timing accurate bottom times and decompression stops.

Flexible decompression
Using the Suunto Deep Stop RGBM algorithm, Suunto D9 enables continuous decompression for optimal ascent time. For deeper dives, the Deep Stop option adds further protection with a series of deep stops between your maximum depth and ceiling.

Plan and review
You can test upcoming dives and view no-decompression time data for different depths before getting in the water with the built-in dive planner. When the dive is over, use the included Suunto Dive Manager PC software to transfer your dive data to your computer for further analysis and to maintain a detailed logbook featuring graphical representation of all your dives.

As stylish on dry land as it is in the water
As well as being a full-featured dive computer, Suunto D9 is a stylishly designed watch that can be worn as an everyday timepiece.
