the current time, shown as TIME
the water temperature followed by °C for
Centigrade [or °F for Fahrenheit].
NOTE! In Dive Mode the TIME / TEMPERATURE
display automatically changes back to DIVE TIME /
CYLINDER PRESSURE after 5 seconds.

3.3.2. BOOKMARK

It is possible to make special marks in the profile
memory during a dive. These Bookmarks will be shown
as a dive log symbol when scrolling the profile memory
on the computer display. The Bookmarks will also be
shown as annotations in the PC-software, Suunto
Dive Manager. To make a bookmark on the profile
memory during a dive press the PLAN button (Fig.
3.10.).

3.3.3. CYLINDER PRESSURE DATA

The air pressure of your scuba cylinder in bars [psi]
will be shown digitally in the lower left corner of the
display. Anytime you enter into a dive, the remaining
air time calculation begins. After 30 - 60 seconds
(sometimes more, depending on your air
consumption), the first estimation of remaining air
time will be shown in the left center window of the
display. The calculation is always based on the actual
pressure drop in your cylinder and will automatically
adapt to your cylinder size and current air
consumption.
The change in your air consumption will be based on
constant one second interval pressure measurements
over 30 - 60 second periods. An increase in air
consumption will influence the remaining air time
rapidly, while a drop in air consumption will increase
the air time slowly. Thus a too optimistic air time
estimation, caused by a temporary drop in air
consumption, is avoided.
