10.4. Dive Setup
The sub-menus in Dive Setup are available both on
the surface and while diving (unlike System Setup
which is not available while diving)�
Define Gas
The Define Gas menu appears the same as the
Select Gas menu, but allows turning gas on or off,
and editing their oxygen percentage (the remaining
percentage is assumed to be nitrogen)�
In 3 GasNx mode gases may be edited and turned on
or off during a dive�
In Nitrox mode Define Gas is found in the top level
menu and the current gas can be edited on a dive�
Turn off gases you are not carrying
The decompression algorithm assumes that the
diver is carrying and plans to use every gas that
is currently turned on� Leaving gases that are
not expected to be used turned on will result
in inaccurate time to surface, decompression
stop and decompression time information being
displayed�

Note:
The highlighted gas is the currently active gas.
You can’t turn off the active gas. You can edit it, but
you will need to switch gases to turn it off.
NDL Planner
The No-Decompression Limit (NDL) Planner is a quick
way to determine how much bottom time is available
until mandatory decompression stops would be
required�

Plan
A surface interval duration from none up to 1 day can
be applied to account for expected off-gassing�
The results are a list of depths, along with the NDL time
at that depth and the best of the programmed gases to
use at that depth� Only programmed gases are used�
The NDL Planner is only available in recreational dive
modes�
