NiTek Dive Computer User Manual 7
• Neither the NiTek—nor any other dive computer—
physically measures the amount of nitrogen present in body
tissues or the rate at which nitrogen is being absorbed or
released. The NiTek monitors depth and time, and uses this
data to work a mathematical formula designed to emulate
how individuals in good general health and whose physical
characteristics do not place them among those at higher risk
of decompression illness (DCI) are assumed to absorb and
release nitrogen from body tissues. Thus, the NiTek cannot
compensate for factors such as age, obesity, dehydration,
cold, or exertion, which experts believe place divers at
greater risk of DCI. If these, or similar factors apply to you,
use the NiTek—and other dive computers or dive tables—
with even greater caution.
• Little is known regarding the exact nature and causes of
decompression illness (also known as decompression
sickness, DCI, or DCS). Susceptibility to DCI may vary
substantially from person to person and from day to day.
Neither the NiTek—nor any other dive table or computer—
can guarantee that you will not suffer decompression illness.
Even though you use these items correctly, you may still
suffer DCI. Use your NiTek conservatively and in
conjunction with other dive planning devices, such as dive
tables. Do not rely on the NiTek, or any similar device, as
your sole means of avoiding decompression illness.
When diving…
• Do not “push” the no-decompression limits (NDLs). Make
safety stops before ascending. If you exceed the no-
decompression limits, check your breathing gas supply at all
stop depths.
• The NiTek does not monitor breathing gas supply. You must
monitor this yourself, on every dive, using a submersible
pressure gauge or equivalent device.
• Do not rely solely on this or any other dive computer. Take a
back-up dive computer or dive tables (along with a separate
means of monitoring depth and dive time).
• Be aware that the NiTek makes assumptions regarding
residual nitrogen based on altitude settings. Avoid making
