For the Suunto's strictly speaking that requires setting them to mountain mode (above 500m) but that has the same effect as conservativism so nobody I know who dives here regularly does that. To that extend that I had friends visiting from lower parts of the country that hat set their Vypers to mountain mode A1 and after a typical dive in the 30m range had more than 30min more deco obligation than me (we skipped most of that of course).

That's exactly what happened to me, at least now I know that this is a
"general" thing with suunto. I prefer this to the situation of going
against the computer while being at 4m below.
