then used in conjunction with a knowledge of the depth dependence to predict
the breathing gas required for a safe ascent including any required decompres-
sion stops.

Breathing gas consumption and depth are continuously monitored, and
Breathing Gas Time Remaining reflects any change in your circumstances.
For example, when a buddy starts breathing from your octopus or you sud-
denly find yourself swimming against a strong current and begin breathing
more rapidly, the Pro Plus will recognize this change and adjust your Breath-
ing Gas Time Remaining accordingly.

Remember, the Breathing Gas Time Remaining is the time you can remain at
the present depth and still surface with the tank pressure reserve (Gas Alarm
Set Point) that you set during setup.  When Gas Time Remaining indicates
zero, you should immediately initiate a controlled ascent.  There is no reason
to panic, the Pro Plus has allowed for the breathing gas necessary for a safe
ascent including any emergency decompression stops.
