mCCR vs eCCR #2 | with Jill Heinerth and Jeff Bozanic

The second part of the mCCR vs eCCR series is here! We bring in CCR experts; Jill Heinerth and Jeff Bozanic to discuss eCCRs where they have been and where they are going! 🤿

Very good quote from Sami Pakkarinen: "You should never expect a dive to go well, because when You do, it never does."

[@johannmattis4842]

The disadvantages of eccrs all come down to the psychological effect and loss of discipline. On "normal" / training- dives I drive my Liberty sidemount manually 90% of the dives + switching to some offboard source mostly during the dive. Some dives even in SCR-procedure to only enjoy the benefits of the eccrs auto-setpoints in challenging dives with higher task-loading.

which is more damaging to the O2 sensors, Time or usage? Say you used your rebreather 100 times in one year, should you replace the rebreather sensors at 6 months/50 dives? If you dive your rebreather twice a year, could you go longer than a year...?

[@ABCDiver]

Think of O2 sensors like batteries: they are electrochemical devices, so the more you use it, the more you "use it up", but even if they are sitting doing nothing, the chemical reaction still happens, just slower; but that's the key part - we don't know how much slower. Manufacturers put 12 months, so in reality they're probably ok for 16-18 months, but you want to be on the safe side. Theoretically, solid state O2 sensors should last much longer when not in use, but the standard PSR-11-39 has a shelf life.
Put it this way, would you risk your life for $300?

Will there be a time when rebreathers are so reliable you won’t need to be concerned with bailout cylinders..

[@coldwaterpixel4184]

i think never... for example e little cut on the brathingloop would flood your rebreather, so that your only option is to Bailout...

[@divesoft_tv]

Likely no, but even with a BOV (Bailout Valve) mouthpiece you switch immediately to your onboard diluent cylinder and that would probably be the most minimum bailout scuba configuration and even that configuration does not have very much range.

[@williamsweet7511]

Love Jill, but she was cave diving before she was certified. No hate, but technical divers are famous for making up their own rules for sure. Pushing the boundaries and exploring is ok for me but not for anyone else. Then someone dies...

In any discipline be very appreciative for the work of our pioneers and vintage forefathers that went before us. Be very respectful of the sacrifices of life given if by unthoughtful human error, poor judgment, or simply an unforeseen accident case. We can honor these departures of life by using the data of the past as lessons learned and apply them to a place of greater knowledge and safer operations in our design, development and operating practices.
I have been in other risk management sports and tend to hate the common persons idealistic arm chair use of the words "IS IT SAFE?". Maybe a better question would be "HOW WELL IS OUR CURRENT TECHNOLOGY UNDERSTOOD?". "Is it safe", quite the contrary we practice what I like to say is a "risk management activity". Let's face it life is not safe. However we have way more "safety mitigations" in place in modern rebreathers than where we came from in the early years affording us greater operational opportunities. We ought to be thankful for the knowledge and maturity we have reached in this discipline of rebreather technology. Yet remembering we still have much to discover and improvements ahead of us especially on the electronic and sensor control side of the equation.
It's a "risk versus reward" type of questions and is a personal question for each individual participant to decide for themselves.
Here is a taste of a rebreather kit in their early infancy: czcams.com/video/xVNsE405UWI/video.html
Enjoyable Dives to All, ❤🤿🤙#SeattleRingHunter

That's kind of the definition of a pioneer - you make up rules as you discover new things. The reason scuba is much safer today is thanks to the lessons from past accidents.
