GAUGE MODE: Should the diver violate the design limitations of the COMMANDER+,
Gauge Mode will be entered since it is impossible for the computer to continue
computing and displaying accurate or even reasonable information. While in this mode,
the only data that will be displayed are Depth, Max Depth, Ascent Rate, Temperature,
and Bottom Time. The COMMANDER+ will continue to compute Oxygen toxicity factors.
The conditions which will cause the computer to enter the Gauge Mode are:
• A dive 100 metres or deeper is performed;
• A Decompression Ceiling of greater than 27 metres is calculated;
• Diver is shallower than the required Decompression Ceiling five consecutive
minutes.
The COMMANDER+ will remain in Gauge Mode for 24 consecutive hours of surface
time. After the diver has been on the surface for 40 minutes, the unit will enter its
“Sleep Mode". The total hours until the unit exits Gauge Mode is displayed in the Time-
To-Fly digits when the unit is again turned on.
