Aladin

Pro Ultra
The dive-planner of the Aladin
®
Pro Ultra always plans dives based on the selected oxygen percentage.
It can be used to:
• calculate maximum depth (MOD, Max. Operation Depth) to be reached with
the selected mixture.
• calculate the necessary mixture (Best Mix) for a dive with a given depth.
The oxygen toxicity is not taken in consideration for the
calculation of the dive planner.
6.1 Calculation of maximum depth
1.Set the desired percentage of oxygen. (see page 40).
2.Activate the dive planner as described before.
3.Observe the depth indications and memorize the greatest depth displayed.
This is also maximum depth for a dive with the set mixture and the set maxi-
mum partial pressure of oxygen.
