With Gauge mode, you can use Suunto DX as a bottom timer.
The timer in the center of the display shows dive time in minutes
and seconds and activates at the start of the dive. The total running
dive time, in minutes, is in the lower right corner.
The timer in the center of the display can be used as a stopwatch by
pressing [SELECT] during the dive.
Pressing [SELECT] resets the main timer and adds a bookmark to the
dive log. The previously-timed interval is displayed below the main
timer.
