About Suunto D9TX

The Suunto D9tx is the world's first all-in-one wrist trimix dive computer. It brings together top-of-the-line features in a full titanium housing with sapphire glass, creating a design that complements a boardroom suit as well as it does a wetsuit. With gas switching between up to eight gases, the same technical RGBM as the award-winning Suunto HelO2, and an easy-to-read 3D tilt-compensated compass, it's the perfect all-in-one companion for adventurous spirits. A trimix-compatible dive computer opens up the increasingly popular world of technical diving including wreck and cave diving by allowing you to explore the depths for longer.

Suunto's innovative tilt-compensated electronic 3D compass redefines underwater navigation. Regardless of the angle of your wrist, you'll have full confidence in the accuracy of your bearings. The Suunto D9tx integrates a digital compass, which can be used both while diving and on dry land, and can be accessed from either the DIVE mode or TIME mode. The Suunto D9tx displays the compass as a graphical representation of a compass rose. The rose displays the cardinal and half cardinal points, in addition to which, the current bearing is also displayed numerically.

The wireless air integration is provided by the optional Transmitter that is easy to install in you first-stage regulator HP port. Suunto D9tx has three dive modes. The Air mode is used for diving with standard air, the Mixed Gas mode for up to eight different gas mixes, and the Gauge mode for use as a bottom timer. D9tx supports Trimix in Mixed Gas mode, and you can accelerate decompression by switching to a gas mix with a higher oxygen percentage. You can preset eight different gas mixes (with oxygen between 8% and 99% and helium between 0% and 92%) and set PO2 values for each individual gas. It's also quick and easy to switch between enabled gas mixes during your dive. In Gauge mode, Suunto D9tx 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.

Using the Suunto technical RGBM algorithm, Suunto D9tx enables continuous decompression for optimal ascent time. The Deep Stops add further protection with a series of deep stops between your maximum depth and ceiling. ??The Suunto Reduced Gradient Bubble Model (RGBM) is a modern algorithm for predicting both dissolved and free gas in the tissues and blood of divers. It was developed in co-operation between Suunto and Bruce R. Wienke BSc, MSc, PhD. It is based on both laboratory experiments and diving data, including data from DAN.

The D9tx Dive Computer is a compact watch style computer that measures 1.94" (49 mm) in diameter with a thickness of 0.68" (17 mm) and weighs a mere 2.96 oz (84 g) without bracelet, so you can wear it every day as a timepiece. Computer has an operational depth display from 0'- 394' (0 -120 meters) and in Gauge Mode will display as deep as 656' (200 meters). Computer is altitude adjustable to 10,000' (3,000 meters), has a 12/24 clock function, dual time, stopwatch, ascent rate monitor alarm, ascent time display, audible alarm, deep stop function, full decompression data, log book memory of approximately 80 hours, maximum depth alarm, personal adjustment features, safety stop function, and displays temperature. You can plan gas mixes, test upcoming dives, and view no-decompression-time data for different depths before getting in the water with the built-in dive planner. After your dive, you can easily transfer your dive data to your computer for further analysis using the optional Suunto DM4 software, which includes a detailed logbook featuring a graphical representation of all your dives.

Computer has a durable rubber wrist strap, comes with a USB Cable, comprehensive Owner's Manual and is covered by a 24 month limited warranty.

Nice computer


I really like the deep stop function. It is very easy to read and operate. I'm a little disapointed with its strap, which is too short and I have to use the extension strat with my semi-dry suit.


great best ever


cant beat it

Questions about this item:

Peter L  Can you wear this as a watch?
DANIEL G  Yes. However, it is a little bit bigger then a standard wrist watch. When we travel to the Caribbean, I use mine as a wrist watch when out and about.
PETER R  Yes of course you can
Brian B  Absolutely, I do it all the time.
Shopper  For a recreational diver is there any advantage to purchasing the DX over the D9TX?
JEFF W  No advantage. I am just a normal recreational diver, but I wanted it in case I end up doing mixed gasses someday.
Shopper  Can u delete logged dives from suunto d9?
Michael C  You should be able to reset the log book. Once the log book is full it will automatically begin to overwrite the oldest dives.
