• Memory functions include detailed dive information such as dive entry time/date, dive time, personal adjustments, possible violation notations, temperature at max depth, surface interval time and scrolling dive profiles with bookmarks.
   
• Nitrox Features - O2 % setting - up to 3 gases containing 21-99% in 1% increments / 0.5-1.6 PO2 in 0.1% increments.
   
• Optional Wireless Tank Data Transmission - 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. The Suunto D9 is available with or without wireless transmitter.
  However, the wireless transmitter is not sold separately. It is sold with the Suunto D9 only. If you want this option, please make sure to purchase it with your Suunto D9 watch.
   
• Three Operating Modes (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.
   
• Integrated Digital Compass - 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 Dive Manager (SDM) is a premium tool for recording, organizing and retrieving dive information from your Suunto dive computer. The program allows easy retrieval and printing of data, creation of dive graphs and addition of notes to the logbook.

The large memory capacity of Suunto dive computers allows you to transfer data such as dive profile, dive time, maximum depth, temperature and air consumption directly to your PC. You can also enter dive locations, buddy names, equipment and other comments just as you would with a conventional paper log.

The simulation function helps you gain greater understanding of decompression theory and computer-assisted multi level diving. It enables you make the most of your Suunto dive computer and is an invaluable aid for instruction. Data can also be uploaded to Suunto's online diving community at suuntosports.com, where you can share information and experiences with other divers from around the world.

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.
