Self Reliant Diver--On All Dives.
Devon Diver wrote,
"If a dive doesn't permit direct ascent to the surface at a constant, pre-determined ascent speed, then it isn't a recreational dive. That speed should enable safe off-gassing from the dive planned, whilst being of sufficient speed to reasonably allow an 'average' capability diver to surface in an OOA (should be LOA) situation."
And,
"That leaves us with a clear definition of 'recreational'... and then,... everything else beyond that."
If PADI had defined or disclaimed the achronym "NDL" the way you just did, my co-student and I, while in our OW class, would not have disagreed with the text. But if they had, NDL would not be an acronym in use today. NDL is a marketing term; its gets people who don't want to do things that may be dangerous, involved in diving.
I was reading some documents produced by DAN. They claim that people die from emergency ascents.

I am trying to make a philosophical point. Un-hinge your mind from PADI marketing. All dives are decompression dives; some happen to require "staged" decompression.
The grey area between rec diving and tech diving can only be defined by the individual. Be responsible for yourself and accept the consequences of your actions. If you are diving below 40 fsw without a redundant gas supply, you are an irresponsible diver (octo and buddy are not redundant gas supplies). And yes, that is MY OPINION based on 40 years surviving oceans. All organizations that teach NDL from 130 fsw and up are irespsonsible agencies (MY OPINON). A diver who does not have proper gear better not DEMAND my help if they get in trouble at depth. markm

“Common factors associatedwith diving fatalities includedrunning out of gas,entrapment or entanglement,buoyancy control, equipmentmisuse, rough water and
emergency ascent.”cite: https://d35gjurzz1vdcl.cloudfront.net/ftw-files/Fatalities_Proceedings.pdf
