Diving In Mountain Lakes; Altitude Ranges; Prohibited Altitude - SubGear XP Air Gebrauchsanweisung

Diving with XP AIR
F
If the dive is made in spite of the microbubble warning, the diver must cope with a
clearly shorter no-stop time or an extension of decompression. Also, the duration of the
microbubble warning at the end of the dive can increase considerably.

XP AIR measures the atmospheric pressure every 60 seconds even while the
display is switched off. If the computer detects a sufficient increase in altitude,
it switches on automatically and indicates the new altitude range (1-4) and
the desaturation time. Desaturation time indicated at this moment refers to
adaptation time at this altitude. If the dive starts within this adaptation time,
XP AIR treats it as a repetitive dive, since the body is offgassing.
Altitude is divided into five ranges, which are influenced by barometric
pressure. That is why the defined altitude ranges overlap on their fringes. If a
mountain lake is reached, the altitude range is indicated at the surface, in the
logbook and in the dive planner by a stylised mountain filled with one or more of
4 segments representing the 4 ranges. Sea level to an altitude of
approximately 1000m (3300 feet) is not indicated. In the following
diagram, you can see the approximate breakdown of the altitude ranges:
