Plan mode
Plan mode enables you to determine how long you can stay at
various depths while remaining within the no-decompression
limits. The no-decompression time limits are based on the
percentage that is set for mix1. If you are making a dive within
24 hours of a previous dive, the no-decompression time limits
are based on the residual nitrogen remaining.
The two most important values that are displayed on the screen
in plan mode are the depth and no-decompression time limit.

(1) Depth:
When you first enter plan mode, the initial depth
displayed is 30 feet (9 meters). You can advance the depth in 10
foot (3 meter) increments. Fourteen different dive plan depth
increments can be displayed to a maximum depth of 160 feet (48
meters).
(2) No-decompression limit (NDL):
Depending on the depth
displayed and the current FO2 setting, the available no-
decompression limit, up to a maximum of 200 minutes, is
displayed. If the computer is in FO2 default, a series of
horizontal lines appear.
If the NiTek Plus calculates that there is residual nitrogen present
from previous dives, the available no-decompression limits are
shorter. Depending on how much residual nitrogen is present, no
NDL time may be displayed for some deeper depths. If this takes
place, a series of horizontal lines are displayed. Similarly, for
combinations of depth and FO2 that would cause a diver to
