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.
Features:
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.
This Suunto D9 has a titanium body and titanium strap and includes a USB- compatible PC interface and the Suunto Dive Manager 2.0 software.
