The Suunto D6 is one seriously good looking dive computer which can double as a stylish watch when you’re on the surface. It is non-air integrated and manages 3 diving modes; AIR, NITROX and GAUGE. It also has 3 operating modes; TIME, DIVE and MEMORY and includes an integrated Compass. The Compass displays direction both graphically and numerically with heading information.

Useability and Features
Even with 4 operating buttons, the Suunto D6 dive computer is surprisingly easy to use. It has 2 buttons located on each side; MODE and SELECT at the top left and top right, while the UP and DOWN buttons are on the bottom left and right of the unit and the combinations truly are simple and logical to follow.
This computer has loads of user-definable features allowing you to personalise it to your own specific requirements. Some of the features you can customise include; backlighting– you can turn it on or off and determine how long it stays on for 5, 10, 20, 30 or 60 seconds. The longer illumination time is fantastic if you take a bit longer to digest the information on the displays. You can preset how the audible alarms behave before you dive –alarms can be set for maximum depth, dive time and time. The alarms sound a continuous beep for 24 seconds, so there’s no chance of you not hearing one!
The Suunto D6 dive computer can even be set to perform the traditional safety stop or you can decide instead to activate the DEEPSTOPS function so you can stop at the recommended points during the dive. Experienced divers are also able to adjust the RGBM (Reduced Gradient Bubbles Model) – the default setting being 100% which gives you full RGBM effect. Adjusting to 50% RGBM applies a smaller RGBM effect but bear in mind this setting also poses a greater risk to the diver.
Gas switching with the D6 is a breeze; while diving, press the UP or DOWN buttons to select the required mix and press SELECT to use it. You can switch between 2 different gas mixes from 21% – 99%.
If you exceed the no deco limits and your dive becomes a decompression dive, the Suunto D6 displays graphical information regarding the decompression range. This continuous decompression feature allows to diver to perform decompression within a decompression range expressed as FLOOR to CEILING as opposed to decompressing at fixed depths during the dive.
On the surface the Suunto D6 dive computer provides all the information and more required for analysis and assistance with planning your next dive. The dive log records all the usual information such as depth and time as well as direction travelled, and retains around 36 hours of diving data. The data it displays is extensive with 3 screens of information you can easily scroll through, including a graphical representation of your dive profile. The dive history feature can record data from 999 diving hours. Planning mode takes into account any calculated residual nitrogen and the dive history from the last 4 days to assist you with planning your next dive.
