The Suunto D9 is a feature rich dive computer that provides many new and enhanced features that cannot be found in other dive computers. This dive computer is a compact and sophisticated multi purpose dive instrument, designed for years of trouble free service.
When underwater a diver needs to monitor several gauges to receive the crucial information about the dive: depth,dive time, tank pressure, decompression status and direction to name just a few. The Suunto D9 combines the complete package of dive gauges and dive-critical information all in one stylish instrument, conveniently mounted on your wrist. Allowing you to concentrate on the diving.
It is the first dive computer in the world to incorporate a digital compass. The compass shows the general direction with a graphical compass rose, as well as the exact bearing with a numerical display. Headings can be stored in the Suunto D9’s memory for later analysis. The compass is naturally functional both on land and under water.
Product Features
Wireless Air Integration
Using the optional wireless transmitter allows the diver to monitor tank pressure and air consumption data. The remaining tank pressure is shown both graphically and numerically, and throughout the dive an estimation of the remaining air time is given. This allows the diver to monitor the air supply remaining at the same time as he monitors depth and dive time.
Real time air consumption is stored in the memory and can be analyzed later using the memory or PC interface functions.
The pressure of more than one tank can be monitored by using multiple transmitters. This can be quite handy for technical divers and for instructors who want to monitor the air consumption of their students.
Multi-mode versatility
Three different dive modes are available: Air, Nitrox and Gauge.
The air mode is for diving with standard air, whereas the nitrox mode provides an option for using up to three different gas mixes during the dive and the Gauge mode for use as a bottom timer.
When in Nitrox mode, you can accelerate decompression by switching to a gas mix with a higher oxygen percentage. You can preset three different gas mixes (with between 21% – 100% oxygen) and set PO2 values for each individual gas. While diving, it’s quick and easy to switch between enabled gas mixes. This feature makes the Suunto D9 particularly attractive to deep and technical divers.
The gauge mode has several applications, such as for freediving. The profile-sampling rate can be set to as low as 1s, and the ascent rate monitoring can be disabled. The gauge mode also provides a dual display stopwatch, which allows the timing of underwater activities to the second. This is extremely useful for timing accurate bottom times and decompression stops. For those intending to go really deep the maximum depth display of Suunto D9 is set at 200m/660ft.
Flexible decompression
Suunto D9 provides the user with an option to use traditional safety-stops, or to use deep stops. The deep stops are calculated iteratively throughout the dive, and the deep stop time can be set to 1 or 2 minutes. The decompression calculations are based on the Suunto RGBM (Reduced Gradient Bubble Model).
Dive Planning and Reviewing
The Suunto D9 comes with a USB interface and Dive Manager software to allow for dives to be easily logged.
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 the included 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.
The extensive memory and logbook functions enable you to keep track of your previous dives and through them you can you can analyze and plan your diving activities.
Summary
The Suunto D9 is as stylish on dry land as it is in the water. As well as being a full-featured dive computer, Suunto D9 is a stylishly designed watch that can be worn as an everyday timepiece.
Safety is essential whether diving in familiar waters or exploring unknown oceans. Suunto D9 is packed with solutions that enable safe and responsible decisions underwater. The depth, time and decompression data, combined with the compass and air integration ensure that you know exactly how much time you can spend underwater, how deep you are, when you have to surface and how fast you can ascend. This way you can maximize your diving performance without jeopardizing your safety.
Suunto D9 is the ultimate instrument of choice for all kinds of recreational, military and professional divers. Competitive divers such as freedivers, as well as technical divers, who do not compromise when it comes to the quality, materials and functionality of their equipment, will find Suunto D9 an invaluable diving aid.
