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.
