REEFS (#3) - gas switch (#28) - Message List
I just bought the Baltic Deco Planner for my iPhone, and I like it. Easy to use and complete.
There is one thing though I do not understand.
First I tried the next profile: -descend to 55 meters, 9 minutes, air (descend rate 7m/s) -stop at 27 meter, 2 minutes, air (ascent rate 10 m/s) I add a deco gas of 50% Oxigen, to be used at 20 meters The app calculates the stops (actually there is only one stop at 3 meters) Nice! And on the graph I see the gas switch at 20 meters. So far so good.
Next I added a stop at 15 meters, 2 minutes, EAN 50% (my deco gas) Suddenly my gas switch at 20 meters disappear!
Is this a bug?
Glad to hear you like it!
No, it's not a bug, it's an intentional decision to delay switching to deco-gases till the end of all levels.
The reason is to accomodate cave divers, where the cave profile might take them to shallows before they're actually on the way out/up. By not switching until the last level is complete, they don't get a profile that constantly flips to/from deco/back-gas as the cave goes up and down.
So to keep your gas switch at 20m, you have to manually re-add it. It's a downside to accomodate both types of divers. It's something that might be an option some day.
