Description: This is the Grand Daddy of combined watch/dive computer and is the world's first dive computer to integrate a digital compass and wireless tank data reception. The Suunto D9 Story. Underwater a diver must monitor several gauges to receive the crucial information about the dive: depth, time, tank pressure, decompression status and direction to name just a few. Suunto D9 combines all dive-critical information in one instrument, conveniently mounted on your wrist. Instead of monitoring a multitude of gauges, you can concentrate on what is important - diving. Suunto D9 is the world's first dive computer 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 Suunto D9's memory for later analysis. The compass can naturally be used on land too. By using Suunto D9's optional wireless transmitter, the diver can also monitor tank pressure and air consumption data from the wrist. The remaining tank pressure is displayed both numerically and graphically, and an estimation of the remaining air-time is given throughout the dive. This allows the diver to monitor the remaining air supply at the same time as he monitors depth and time. Real time air consumption is also stored in the memory. Suunto D9 can be used with up to three different gas mixes containing 21-100% oxygen, allowing gas switching during the dive. Decompression calculations are based on the Suunto Deep Stop RGBM model, which provides iterative deep stops as an alternative to traditional safety stops. For those intending to go really deep, the maximum depth display is set at 200m [660ft]. In addition to basic dive data, the built-in dive logbook provides a graphical dive profile where real time water temperature and tank pressure data can be analyzed on the wristop computer. The sampling rate can be set to as low as 1s. The beautifully designed Suunto D9 has a titanium housing and includes an USB-compatible PC interface and the Suunto Dive Manager 2.0 software. Deeper Understanding Instead of monitoring information from several sources, Suunto D9 provides you with all the crucial information from a single source, conveniently mounted on your wrist. The integrated digital compass can be accessed from both DIVE and TIME modes, and provides a graphical compass rose display and numerically displayed bearings. Bearings can be locked, and visual aids are provided for navigating set courses or for pattern navigation. Headings can be stored in the memory for later analysis using the memory functions or the PC interface. Suunto D9 can be used with the optional Suunto Wireless Transmitter. When enabled it provides the diver with tank pressure and air-time information, as well as a tank pressure bar graph. Real-time tank pressure data is stored in the memory, and can be later analyzed using the memory or PC interface functions. Three different operating 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. 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. The maximum depth display of Suunto D9 is 200m/660ft. 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 2min.
