Descent Mk2i Locked to Gauge Mode

A few limited studies have been done with civilian divers. But even those generally just looked at incidences of clinical DCS symptoms and sometimes bubble scores. I'm not aware of any that actually biopsied tissue and measured inert gas saturation to quantitatively validate the Bühlmann ZHL-16C Algorithm. That doesn't mean it's wrong necessarily, but only a fool would have confidence in it for the scenario under discussion here.

Thats right i think there was a thing about deep stops being good on decompression dives then they discovered that while it alowed off gassing for slow tissues, medium and faster tissues would off gas enough to cause air emboli, theory failing on meeting practice, theres a good video on this by australian dr that i cant find now if anyone has link id be grateful.

On a related note bhulman c is a modification of bhulman b that was made for the chipsets of the first dive computers because they couldnt process bhulman c, bhulman b should be the protocol as per ratio dive computers.

Given power and expense of mk2 why cant it also run vpm algos, ratio dive computers for example can run bhulman and vpm concurrently to allow switching.  Considering cost of descent it comes with alot of limitations others dont which given price is unacceptable tbh, like customising the dive screens etc.  I love the watch and the all in one but i am starting to wish id gone with a fenix, or even mk2, and got a mature dive computer like sherewater, ratio or new suunto eon instead.  Sherewater being most versatile fanboy status aside

Yes I've seen that study. It's interesting but not particularly useful, in that in compares dive computer algorithms to historical Navy dive profile outcomes. Not really applicable to recreational divers doing multiple repetitive dives over multiple days.

The whole concept of a "no stop time" or "no decompression limit" reflects a fundamental misunderstanding of decompression. While you can get away with it (avoid clinical symptoms) most of the time, a better approach is to treat every dive as a decompression dive regardless of what the computer shows. Empirically this seems to give better results for repetitive diving, although there hasn't been any real research in this area. So who knows.

Incorrect, it went into guage mode during a snorkel on my first day before locking me out for 24 hours.  Rest of the trip has been used in single gas mode, once it unlocked itself.  

Was guage mode the mode you were in the last time you used it?

Was a solve determined for this? I entered gauge mode for a gas dive by accident and am now unable to change back for 24h, despite not doing an actual gauge dive.  Brand new watch for me, so this is pretty disappointing to be unable to reverse.

I never managed to solve the issue, I even went as far as trying to reset the computer to factory settings but it retains the lockout in the memory.   I just had to wait out the next 24 hours which was really frustrating, and made a mental not to wear it snorkelling if I planned on diving under the surface.  

Thanks
