VI Dive Planner
The dive-planner of the Aladin
®
Pro Nitrox always plans dives based on the selected oxygen percentage.
It can be used to:
– calculate maximum depth to be reached with the selected mixture.
– calculate the necessary mixture for a dive with a given depth.
6.1 Calculation of maximum depth
1. Set the desired percentage of oxygen. (see page 39)
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
maximum partial pressure of oxygen.
6.2 Calculation of the mixture for a given depth
1. Activate the dive-planner and observe the
maximum depth displayed.
2. If the desired depth is reached or exceeded, leave
the dive-planner, alter the percentage of oxygen
and return to the scrolling no-stop times. Repeat
this procedure until the desired depth occurs as
the maximum depth.
3. In ready-mode, the ideal percentage of oxygen
for this depth is indicated.
