8.5. NDL Planner
The No-Decompression Limit
(NDL) Planner is a quick way to
determine how much bottom time
is available without the need for
decompression stops�
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�

A Gas Usage screen gives a total gas consumption
report and a dive summary screen shows the total
dive time, the time spent on deco and final CNS%
after the last page of the decompression schedule�
If no decompression is required, no table will be
shown� Instead, the total No-Decompression-Limit
(NDL) time in minutes, at the given maximum depth
will be reported�
