PDIS (Profile-Dependent Intermediate Stop)

[DivePassion]

Hello

What do you think about PDIS ?

PDIS (Profile Dependent Intermediate Stops) optimizes your dive by calculating an intermediate stop based on how much nitrogen uptake your body has endured, taking into account your current dive, previous dives and breathing mixes. PDIS is a unique scientific application for safer technical and recreational diving.

Perhaps on Ver. 2.70 ??

It's proprietary to Uwatec. There's not much to "think" about, as there is no published scientific paper I know of which could explain the theory and how it has been tested. It's like their 'MB level' of some years ago: you had the choice of several "levels", but no data was given as to how this deviated exactly from the Bühlmann model ...

My opinion: why waste time trying to reverse-engineer that thing ?

PDIS is some kind of a deep stopp...

Yes, but everyone is creating runtime tables with V-planner and
conservatism +2, but no one knows what this +2 will do exactly.

"Additional Security", "Conservatism" or "Personal settings" are
good for the mind. And if the mind is good, the deco is good too (:P)
