most computers alarm if your ascent is too fast.
Give the lady a prize!
I skimmed the previous pages pretty fast so forgive me if I missed somebody else saying this, but I was looking for it and didn't see it.
Ascent rate monitors and alarms are huge reasons why computers beat the heck out of watches, depth gauges and tables. (You can get an air computer for dirt today, at least as cheap as a reliable watch, depth gauge and table.)
The average new diver is not usually very skilled at ascents and the old methods certainly don't help much.
There is no question a slow ascent is key to all divers safety, no matter how basic.
The new computers even have built in safety stops.
I've been teaching students wearing computers since the Suunto SME ML debuted, about 1985/6. Wouldn't want it any other way. I had an Edge a year or so before.
