Full Review

With its titanium housing and band, the Suunto D9 dive computer is superbly designed and looks amazing. With optional wireless air integration, gas switching for up to 3 nitrox mixes, a full featured watch and an integrated compass, the Suunto D9 is everything you need both on the surface and while diving. This computer incorporates 4 easy to use push buttons which include a display that advises and guides the user through the settings. All this plus an operational depth to 100 m and the Suunto D9 is the complete package for divers with any level of ability.

Useability and Features

The Suunto D9 dive computer enables the diver to turn the wireless air integration on or off and typical of the Sunnto computers there are loads of other user definable features the diver can setup according to their specific dive situation.

An example of such a setting is the Depth alarm which is set for 40m at the factory , but is user adjustable anywhere from 3m to 100 m. You also have the ability to change between being prompted to perform a Safety Stop or Deepstops, with the display and alarms changing according to the choice that was made. The optional wireless cylinder pressure transmitter is installed in the high pressure port of your regulator, and if you’re pretty comfortable with adjusting your own gear this is something you can easily do yourself. Not only does wireless transmission give the diver tank pressure information, it has the added benefit of displaying Air Time Remaining based on current cylinder pressure, your current breathing rate and ascent rate.

Best Dive Computers - Suunto D9tx ReviewThe Suunto D9 dive computer has a 35 bar safety reserve, so even though it might display 0, there’s still around 35 bar in your cylinder. There is a default cylinder pressure alarm which is factory set at 50 bar, however there is a secondary pressure alarm which can set to anywhere between 10-200 bar. The Suunto D9’s backlighting can be turned on or off and has settings which allow the diver to change how long it illuminates for, with options from 5 – 60 seconds in varying increments. Be aware that if backlighting is off the computer will not illuminate when an alarm sounds, which might make seeing critical data difficult if you are diving in a low light environment. The Suunto D9 has 3 personal adjustment modes you can program that are designed to build in more safety with shorter no decompression times. This feature can truly be a life saver if you think particular diving conditions might become more difficult. If you are very experienced and willing to accept more risk when diving, you can even adjust the RGBM model to from 100% to 50%, which applies smaller RGBM effects, but also means you are exposing yourself to a higher risk.

Of course, the Sunnto D9 dive computer displays all the key data you need to see while diving, and depending on how much detail you require in your diving environment, there are alternative screens accessible by simply pressing the UP/DOWN buttons. Like the Suunto D6 dive computer, there is also a Continuous Decompression feature which the Suunto D9 uses to perfectly manage required decompression stops by showing you the Ceiling Depth, Ceiling Range and Total Ascent Time.

On the surface, the Suunto D9 lets you view your Surface Interval, No Fly Warning and review any violations that might have occurred during your dive such as mandatory safety stop omissions. Also available to you is a planning feature to assist you in preparing for any repetitive dives, and you can view the dive log which has a high capacity profile memory. During your pre-dive setup it’s possible to adjust the dive profile sampling rate which is preset to 20 seconds, but changeable to 1, 10, 30 or 60 seconds, remembering that the sampling rate chosen affects the number of dives which can be stored on-board. A PC interface is part of the Suunto D9 dive computer package and includes Suuntos’ Dive Manager software for downloading and logging your dives on your laptop or PC.
