Multi-Gas Diving; Modifying Gases During A Dive - Suunto EON CORE 2.0 User Manual

Suunto EON Core
indicates depth, and a white line shows temperature. If you dive with Tank POD, tank pressure
and gas consumption graphs become also visible.
The last page of the logbook contains further data. Press the middle button to find average
depth, CNS percentage, and OTU value.
For more detailed log analyses, upload the dive(s) to Suunto DM5 (see 3.33. Suunto DM5).
When the logbook memory gets full, the oldest dives are deleted to make space for new
ones.
NOTE: If you surface and then dive again within five minutes, Suunto EON Core counts
this as one dive.

3.24. Multi-gas diving

Suunto EON Core allows gas changes during a dive between the gases defined in the Gases
menu. When ascending, you are always notified to change gases when a better gas is
available.
For example, you may have the following gases when diving to 55 m (180.5 ft):
tx18/45, MOD 62.2m (pO
•
tx50/10, MOD 22m (pO
•
oxygen, MOD 6m
•
While ascending, you are notified to change gas at 21 m (70 ft) and 6 m (19.7 ft) according to
the maximum operating depth (MOD) of the gas.
A pop-up notifies you when to change gases, as shown below:
WARNING: When diving with multiple gases, remember that the ascent time is always
calculated with the assumption that you use all the gases found in the Gases menu. Always
check that you have only the gases for your current planned dive defined before you dive.
Remove the gases that are not available for the dive.
