Dive At High Altitude
Air pressure (Ambient pressure) at high altitude is lower than one
on sea surface. Higher the altitude in dive is, more difficult the
decompression condition becomes compared to the sea surface.
The dive computer auto-measures air pressure in every 20
seconds and sets the current air pressure properly to calculate
for decompression. You are free from worrying the altitude you
are at and can enjoy safe dive according to the altitude. However,
you must remember that non decompression limit (NDL) is much
shorter in the dive at high altitude than in the sea. Dive at high
altitude increases the risk of developing decompression illness.
Please keep in mind that you should not have decompression dive
in high altitude.
The computer measures the pressure of atmosphere every 20
seconds, and constantly calculates the Desaturation time from
the difference with the bodily nitrogen pressure, unlike other
conventional products which measure the exit point pressure
and displays the Desaturation time by reverse calculation timer
from the difference with the bodily nitrogen pressure at that
time. For this reason, the Desaturation time may vary due to
ambient pressure changes such as changes in the weather,
going to high altitude road by a car or getting on an airplane.
