6 Diving in Mountain Lakes
In order to assure optimal decompression also at higher altitudes, the 3 m decompression stage is divided into
a 4 m stage and a 2 m stage (the prescribed decompression depths are in consequence 2 m, 4 m, 6 m, 9 m...).
Aladin
®
Pro can be used as decompression computer up to an altitude of
4000 m. If atmospheric pressure is below 620 mbar (higher altitude than 4000 m
above sea level), no decompression information is displayed any more. Dive-plan-
mode can no longer be started, since no decompression information is available.
Beside the display of the altitude section 3, <HI> (=high) appears to tell the diver
that he will not get any decompression information for the dive.
Very small differences in the pressure sensors can cause an indication of different
altitude sections of two dive computers at the same altitude on the fringes of the
altitude ranges. These differences are not meaningful and do not interfere with
the safety of Aladin
®
Pro. But if an altitude section is displayed at sea level or the
altitude informations of two computers differ by more than one altitude section
(e.g. section 2 instead of 0), there may be a defect of the computer. In this case,
send your computer back to your retailer for checking.
