3.13 Dive modes
By default Suunto EON Steel has three different dive modes: Air/
Nitrox, Trimix and Gauge (bottom timer). Select the appropriate
mode for your dive under Dive settings / Mode.
NOTE: Air/Nitrox dive mode is a single gas mode. The Gas(es)
menu under this mode will not allow you to add more than one
gas. However, this can be changed through customization. See
3.9 Customization.
NOTE: All default dive modes use the graphical interface style.
You can change this and other settings, as well as create additional
dive modes using Suunto DM5. See 3.9 Customization.
Air/Nitrox and Trimix modes are intended for diving with
decompression information, like no decompression stop time or
decompression ceiling/ascent time.
