The Suunto D6i is an excellent dive computer, only 1 model down from the flagship D9tx. Sharing most of the features of it's big brother the main difference is that the D6i doesn't have the trimix feature. Instead it is available to use as a full blown 3 gas switching technical dive computer and able to cope with mixes between 21% and 99%. So is good for dives up to the "Advanced Nitrox and Decompression Procedures" level of diving. It is as elegant as a wrist watch as it is perfect for diving. The watch can be worn happily on the wrist and is a stylish addition to a divers fashion, looking great in the pub, at work or strapped to your drysuit. If you buy this model it is still possible to add the steel strap at a later date, which can be done at any Suunto dealer or nuy the strap online and DIY with a small Torx driver.
It also features the innovative 3D tilt compensated electronic compass. With cardinal marks and the ability to lock in a bearing Suunto have excelled themselves with a range of computer features that their competitors will find it hard to match, who else could produce a computer that provides direction arrows to keep you on track. The compass also facilitates guided calibration and declination setting.
In air mode it works as a standard and decompression dive computer with the full RGBM Suunto deco model. Using this algorithm, the D6i 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.
In Nitrox mode, you can accelerate decompression by switching to a gas mix with a higher oxygen percentage. You can also preset two different gas mixes (with between 21% and 99% oxygen) and set PO2 values for each individual gas. It’s also quick and easy to switch between enabled gas mixes during your dive. In this setting the RGBM is also used and has been calibrated to work with other gases and dedicated higher% nitrox decompression.
In Gauge mode, the Suunto D6i works as a bottom timer, and also provides accurate profile sampling and bookmarking functions. A dive timer with a reset function displays your dive time in minutes and seconds. This is extremely useful for timing accurate bottom times and decompression stops.
If you’re serious about breath-hold diving, the new Freedive mode puts all the functionality you need at your fingertips by sampling depth three times a second, it gives you highly accurate data on the true depth reached rather than the approximate depth you find with slower sampling computers.
If you'd like more information you can also download the Suunto D6i manual from the Suunto website.
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 optional 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.
