it sounded like from the article posted in the A&I thread that that resolved as the chamber treatment started

I dive Shearwater because I like the fact that it will never lock me out and I consider it a superior product for decompression diving.
It's certainly true that, like all "pure" ZHL machines, a Shearwater will always display an ascent profile. The downside to this is that it may under some circumstances display a dangerously incorrect one.
Can you back up your assertion with empirical data or research
I'll never get around to the idea that an in-water lockout is ever a good thing. I got a computer to provide information throughout the dive. My computer should not throw a tantrum and give me the silent treatment while in the water. I'm not a fan of post-dive lockouts either, but I understand that a little more.I'm someone who deals in trade-off and not absolute. The lock out seems a sensible option depending on the circumstances. And the more you insist on simple options because we are in Basic Scuba, the more sensible it looks along with the user guide instructions of going to 5 meters and empty your tank.
I know you've done more research on this than I. However, I'd still prefer a computer that will do its best to provide information during the dive. Perhaps not ideal, but IMO better than providing no guidance to stops at all.It's certainly true that, like all "pure" ZHL machines, a Shearwater will always display an ascent profile.

The more one argue that this is Basic Scuba and that the public don't know anything about deco, the more a lock out look sane (*). It is less so for people who know more what they are doing, the limits of deco algorithms and what could be done when they are overstepped. Yet, I'd appreciate a more noticeable and permanent info that the known validity envelop has been broken.I'll never get around to the idea that an in-water lockout is ever a good thing.
There is a big difference between in-water lockout and a post-dive lockout. I understand the reasoning for post-dive lockout. I don't currently dive with any computers that will lockout, but that's a personal choice.The more one argue that this is Basic Scuba and that the public don't know anything about deco, the more a lock out look sane (*).
Regardless of level of knowledge on deco algorithms, the computer should be designed for those divers who are willing to check it periodically, understand what it is telling them, and do their best to follow the guidance. There must be better options than to turn off that guidance during a dive when a parameter was not met to the satisfaction of the programmers.It is less so for people who know more what they are doing, the limits of deco algorithms and what could be done when they are overstepped.

How about providing a profile that does not immediately violate good diving practices? If you get DCS from that ascent (which is likely), then what is the purpose of talking about the later parts of the dive?rapidly ascends to the surface at 50m/min

You two guys can go off and play your silly games with extreme profiles. Count me out.Isn't this whole part of the thread about what the computers do when violating good diving practices?
