Using the NiTek Duo

24 NiTek Duo Dive Computer User Manual

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 appears.

If the NiTek Duo 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

exceed a limiting PO2 of 1.6 atmospheres, a series of horizontal

lines appears in place of the no-decompression limit.
