Many divers who are professional, military, recreational or even competitive freedivers that take the quality, functionality and material of their diving computer very seriously have considered the Suunto D9 to be an invaluable diving aid. The thing that distinguishes this device from all the other dive computers is that not only does its state of the art features fit perfectly for all sorts of diving but they are committed to promoting diving safety in all areas of the dive.

When you are diving in a place that you are totally unfamiliar with, then features of the Suunto D9 diving computer such as the depth, time and decompression data, along with air integration and compass will prove more than useful. You will be able to know exactly how much time you can spend underwater, when you have to surface and how fast you can ascend, and you will also be able to know how deep you are when underwater. These features in the dive computers alone will cover your diving safety while maximizing your performance at the same time.

Features

The features of the Suunto D9 diving computer will not only amaze the most professional divers but it will also amaze novice divers and people who have never been diving or seen dive computers before. Its well known features are:

The Digital Compass

The first dive computer to have an integrated digital compass was the Suunto D9. The direction on the digital compass is shown through a graphical compass rose. The exact bearing can also be shown in a numerical display and the headings can be stored in the memory of the Suunto D9 for later usage. This digital compass can also be used on land as well which makes it perfect for any outdoor extreme sport.

Optional Wireless Transmitter (Air Integration)

The diver can monitor critical information, like tank pressure and air consumption, with this feature on the dive computer. Displays of the remaining tank pressure can be shown both graphically and numerically, while the remaining air supply is given throughout the entire dive by this dive computer and will prove very useful as the diver will know how much time to spend underwater. Most dive instructors and technical divers will find this feature very useful in what they do. Another thing this feature has to offer is that it can store the real air supply time in its memory.

Deep Stop Option and Multiple Gas Mixes

This feature enables the Suunto D9 diving computer to use up to three different gas mixes containing 21-100% oxygen and allows the diver to switch gases during the dive. The Suunto Deep Stop RGBM (Reduced Gradient Bubble Model) is where the decompression calculations are based on and it provides iterative deep stops as an alternative to safety stops which can be used as well which adds extra safety. Deep and technical divers may suit this feature well as it also has a maximum depth display set to about 660 ft. (200m).

Integrated Dive Logbook

A graphical data profile is provided through this integrated dive logbook where real time water temperature and tank pressure data can be analyzed on the dive computer. The dive log also enables you to store extra information about the dive site, conditions, equipment, notes, and even photos from the dive since the Suunto D9 comes with PC software and is USB compatible.

Some Weaknesses

The air integration wireless transmitter can be a problem only if you forget to activate it before the dive, according to some reviews on Suunto D9 dive computers. If you forget to take a spare SPG when this happens then you will have to resurface in order activate it. Something else to take note of is that the PC software for the Suunto D9 is not available for Mac.

In Conclusion

The Suunto D9 diving computer is undoubtedly the golden standard for all dive computers and is the forerunner for future dive computers. It has everything that is needed in a dive computer from its stylish appearance to its digital compass that can be used anywhere. It has a complete package with air, nitrox, and gauge modes, along with its black elomaster and luxury titanium straps and Suunto Dive 2.0 software. You will not be disappointed with this range of dive computers.
