Sport demands a decompression stop within the no stop phase because of the danger of the formation of microbubbles Decompression time necessary for the prevention of microbubbles can increase massively if the ascent rate is exceeded From great depth too slow an ascent causes super saturation of tissues and an extension of decompression timeand total ascent time From little depth shortening of decompression times is possible because the tissues already start desaturating during the ascent 30 Ill Diving with Aladin Sport 4 Functions during the Dive EBE 4 5 Decompression information No stop time is displayed if no decompression stops are necessary yet The arrow lt NO STOP gt is visible The figures indicate no stop time in minutes dive time No stop display lt 99 gt means remaining time of 99 minutes or more No stop time is calculated assuming normal workload and current water temperature max depth deco info wann Messages In the last minute of the no stop phase the no stop display shows ti ot the flashing value lt 0 gt 2 l IL max depth deco info Action In order to prevent a decompression dive you have to ascend a few metres after this message Ill Diving with Aladin Sport 31 4 Functions during the Dive EBE Decompression values dive time max depth deco info Messages On entering the decompression phase the arrow lt NO STOP gt extingu
