    Ok, I only caught part of the video,..... but, the given the uproar and fury over cells, cell integrity, and linearity lately...

    Did anyone else interpret Kevin's comments as saying there is no need for cell checkers and linearity checking; specifically mentioning Teledyne's....

    I think he said that r17 and r22 are perfectly linear!? Hmm..

    I want a Sentinel and I want one NOW!!

    Yeah I wondered about his comments on cell linearity too, I'm pretty sure he's got some data to back up his claim, it remains to be seen

    I was the one that asked the question. Earlier on in the day Kevin said that most problems were not caused by the cells but with other issues moisture and corrosion etc. From what I can tell he had faith that the cells are linear.

    Alternatively, a working cell is linear and therefore you can calibrate in air. This is absolutely true, but is your cell working correctly?

    Why not decide for yourself?

    The NATO Research Dive team did, so did NOAA, Diving Diseases Research Centre, British Navy, Analytical Industries, the list goes on. And dont forget the £85,000 Divex Stealth has one built in.

    Lastly, cells obviously do fail. APD stated upto 30% failure rate of cells, Aii cells have failed miserably and I'm sure many of you have experience of call failures.

    Trust the cells, not the rebreather... dont trust any thing.

    My guess is that there is a some sort of misunderstanding here about cell checks. I was asking Kevin about this and he thinks that cell checkers are nice to have feature, but it does not mean that rebreather should not check linearity during a dive. In other words, a kind of real-time cell checker must be embedded into electronics itself, to do the job during a dive, like it currently is at Sentinel & OR mCCR. I personally consider these two models as most advanced breathers at today's sport market in regards of PPO2 control & fault-tolerant architecture.
