1.3 Minimizing risks on repetitive dives
There is still excess nitrogen in the body due to the history of the preceding dive. Depending on the duration
of the surface interval, there may even be gaseous nitrogen (microbubbles). You can minimize the risk by
observing certain rules:
– observe the same rules for repetitive dives as on your first dive
– plan repetitive dives at a smaller depth than the first dive
– plan a sufficient duration of the surface interval (min. 3-4 hours)
–
only go on repetitive dives, if no indication <Atn> is visible on the display
– plan a day without diving once a week
– avoid exertion at depth and during the ascent
– make sure you always have enough air for the ascent
1.4 Action in risk situations
If the dive includes a risk situation, Aladin
®
Pro reacts automatically and appropriately to the situation. A
change of decompression is indicated if it is actually necessary to minimize the risk. The diver can further
reduce the risk through sensible conduct on the next dive and at the same time prevent long decompression
stops.
A few examples are given on the following pages:
