Ascent Rate - Suunto VYPER NOVO User Manual

The apnea timer supports up to 20 intervals, but this is dependent
on the ventilation and increment times. The last ventilation cycle
cannot be shorter than 0:05 seconds or longer than 20:00 minutes.
WARNING: Anyone who engages in any form of breath hold
diving is in danger of shallow-water blackout (SWB), the sudden
loss of consciousness caused by oxygen starvation.
