The Suunto D9 Dive Computer – A Look at the Features From Suunto’s Top of the Line Dive Computer

Known as the first all-in-one dive computer, the Suunto D9 contains all the features needed for the most demanding of divers.

This top of the line computer from Suunto brings all the crucial dive information to ensure your safety during, and post, your dive, in one great piece of equipment.

Now let us take an in-depth view of the features which make up this great piece of diving equipment.

Wireless air integration

A great feature of the dive computer is its wireless air integration capabilities. You do however need to purchase the wireless transmitter separately, although you may find the complete package here.

The wireless air integration enables you to keep track of your air consumption and tank pressure and at the same time monitor depth and time. The remaining air time is numerically displayed during the dive whilst tank pressure is displayed in both numerical and graphical representation.

Digital navigation

The greatest feature of the Suunto D9 is its digital compass which is fully functional above and below water. Designed with the diver in mind, the compass can be accessed from both Dive and Time modes enabling continuous monitoring of other dive data. A graphically representation of a compass rose displays cardinal, half cardinal points and the current bearing which is numerically displayed.

Multi-mode features

With multimode versatility, Air, Nitrox and Gauge Mode, the D9 is designed to meet even the most demanding diver’s expectations. Whilst the Air mode is used for scuba diving on standard air, the Nitrox mode can be used for up to three nitrox mixes, whilst the Gauge mode is meant for use as a bottom timer.

Particularly suited for technical and deep divers, In nitrox mode, the Suunto D9 has the capacity to handle up to 3 different gas mixes which can be set between 21% to 100% oxygen and you can then set PO2 values.

A very useful feature of the D9 is the recording of accurate bottom times, deco stops and profile sampling through the Gauge mode. Moreover in this mode a dive timer provides you with your dive time in minutes and seconds.

Decompression Calculation

The D9 uses Suunto’s deep stop RGB algorithm to base the decompression calculation. Further safety is added using this algorithm where continuous decompression for optimal ascent time is calculated.

When enabled the Suunto D9’s user-selectable deep-stop function calculates the first deco stop at half of maximum depth. Extra safety is also provided for deep diving where a number of deep stops between maximum and ceiling depths are added.

As for no-decompression dives, you will be alerted for a three minute safety stop at 15 feet.

Memory and Dive Logging

You can easily connect your Suunto D9 to your PC using a USB interface and Suunto’s Dive Manager (SDM) software to transfer and view your previous dives.

The SDM will portray a complete click-able graphical representation of your dive profile for you to better understand and keep track of your dives.


Whether you are diving in unknown waters or diving to depths, safety is your greatest priority. This Suunto D9 is designed to enable you to practice your favorite past time whilst knowing that you can rely on the information provided by this great dive computer.

Given the complete package of dive gauges all combined into one instrument, the depth, time and decompression information combined with the digital compass and air integration you can make better decisions and maximize your diving performance without making unnecessary risks.
