On www.thueringen.de/de/lka/aktuell/presse/pm/10774/uindex.html there is
shown what the police thinks to have been the cause of the acident. Pics
show a badly warped checkvalve, which may have been leaking, or stuck
closed.

Imho redundancy and/or a more reliable checkvalve( like one with mica
disk) would have prevented an accident ( if stuck, not if one was
leaking)

[caveseeker7]

The German message boards have been aflame with this accident. Thanks for the link to the LKA's (state police investigators) official version. Makes sense they asked Buchaly to be an expert witness as the EDO is a copy of the RB 80. And Reinhard Buchaly is the RB. Buchaly's dive partner, 'db8us' Waldbrenner, pointed out a while ago that the quality & materials used in the EDO were inferior to the RB80. No kidding.

The deceased was on his 4th dive with the unit, solo, not having received certification (if there is any, or training for that matter). Not the way to go.

From other reports he was diving in about 20m when fishermen and other people lakeside realized the dive light stopped moving. When they tried to get help from the local base/shop, they were sent away and ended up calling authorities themselves.

Sad incindent. :(

[pwfletcher]

Does that unit have any elcectronics that monitor O2 levels? If not, do you think that it may have saved the diver if it had such monitoring devices?

[caveseeker7]

No, the EDO04 not only comes without monitoring device (such as an Oxygauge), but unlike the RB80 it doesn't even have a sensor port to put one in. Major mistake in my book. The guy could, however, rigged something fairly easy. The EDO04 has Dräger breathing hoses, so he could have used an Oxy2 (dual O2 cells) for monitoring. Those however are supposed to be used with the Uwatec ZO2, which calculates nitrox, not helium.
The guy was a caver, had a dual rig, might well have wanted to use it with trimix or heliox ... :(
He could have fit a VR3, Explorer, or Oxygauge, in there, too, with some drilling and the P-connector.
But from what I understand even the RB80s are used without O2 monitoring, unless for training purposes to show students just how little the O2 drops (in comparisson to CMF units). Not my kind of thinking, but the DIR boys don't like electronics much, and I guess another used port is another potential failure point.
The RB80 has an excellent track record, but if I remeber right quite a few cave dives have been done on EDO04s in Europe, some of them pretty deep penetrations.:rolleyes:

[caveseeker7]

pwfletcher once bubbled...
If not, do you think that it may have saved the diver if it had such monitoring devices?
Probably if not likely. If you look at the pictures Padiscubapro's link leads you to, you can see the deformed one-way valve. That's the one that keeps the gas that flows into the small, inner bellows from returning into the loop. That's the gas that is supposed to be released, and then replaced by fresh gas from the tanks. Gas addition is triggered by a pair of rods when the bellows 'bottoms out'.
If the breathed gas in the inner bellows gets back into the loop because of a faulty one-way valve, or a leak in the bellows, no new gas will be added. The same gas is then rebreathed until O2 levels are too low to sustain life. Kinda like a CCR without O2 addition. He broke the 1st rule: ALWAYS KNOW YOUR PO2!
I haven't had a chance to try the RB80, but Waldy said you can hear the gas addition easily. He and Madmole were talking about this sort of leak as a potential failure point in RB80s. So the divers inexperience on the unit (his 4th dive), and maybe lack of training/knowledge (he didnlt know what to look and listen for) might have been a contributing factor. Pre-dive checks on the day of the accident I don't know about.
While they haven't finished the investigation, I'm pretty sure the valve as shown doesn't work as it is supposed to. If the diver died, as they currently believe, of hypoxia I'd say either O2 monitoring could have prevented the accident and/or a dive buddy could have saved the diver.

Madmole's quest for safer RB diving just got another sad example:
Never disregard the 1st rule and never dive solo on a(ny) rebreather.

Did you write that, Padiscubapro, or is it part of Buchaly's post?
2 rebreathers seems redundant, and I assume he had OC bailout (there are two green hoses going out of the last picture that could well have 2nd stages on them. What's a mica disk?

My thought, how can a check valve end up like that, was answered when someone else asked the question on DiveOz. Jason McHatten had the same happening to the check valves of his MK15 when he cleaned them with hot water ... .
Something to think about when rinsing the loop.

Of course testing those valves is part of the setup process (if you are DIR) and only takes a few seconds. After seeing those pictures I doubt I would ever forget that check.

No that portion was added by another fellow Matthias Voss, it seemed like a good assessment so I left it in place..
Mica is a mineral that when thin is flexible and resistant to high temperatures.. it can be used alone as a diaphram or as a backing to stiffen things up..

[db8us]

He "should" have noticed that the unit is not venting any gas at all.
But if you have no understanding of the unit, because nobody explained it you are lost.

Letīs assume the flapper valve failed from beginning of the dive...
On the way down everyhing seems normal, cause the CL will be squeezed by pressure and so the unit WILL inject.
So the diver thinks: ALL is OK.
The max depth was almost 20m, but he went upwards without any substantial bottom-time.
There he might have purged the unit through the nose and therefoe thinks: "All is OK" because when exhaling through the nose of course gas (purging the loop) is injected.

So now his dive was "almost over" and due to the fact that he was diving solo he relaxed and stayed in the warm shallow part of the lake (aroun 2mm) thats 6feet !!

There the **** hitted the fan, because he WAS NOT MISSING the sound of the venting and injecting.
Maybe because nobody told him about the importance or how exactly such a unit works.
As Caveseeker said fishermen notcied his light not moving....

A buddy could have just put him "on his feet" and would have saved his live.
A sad unnecessary loss....

Caveseeker is also right, they tried to save a buck wherever they could, so parts made out stainless steel on the RB80 where out of plastic, other instead of teflon-coated aluminium also out of plastic. The port for the Oxygauge left out...cheap Ray-hoses without integreated bailout mouthpiece...

The "manufacturer" has NOW 80 dives on the unit and yet is selling it since May.

How should they pass on knowledge and/or experience ?
They just did a bad copy without getting the full picture...

Michael

Of course there are laso pre-dive checks .....

[padiscubapro]

I never saw anything that said the unit wasn't venting ANY gas.. even as bad as those valves looked there was probably some fresh gas exchange, but it would be a losing battle the po2 would be gradually falling, if there was no exchange PO2 falls rapidly and symptoms may show themselves, a very slowly dropping po2 is more likely to first effect ones cognative ability, followed by unconsciousness then death.. the fact that it was sustaining life in deeper water leads me to believe he was getting some gas exchange, in 2m water the po2 drop would be fairly rapid as opposed to 20m.

If some gas was venting, it probably seemed to be working well.. its hard to judge volume just by sound.. its more like bubbles or no bubbles.. a total fauilure of the valve would be simple to spot, a leaky or intermittent valve could possibly be missed in predive checks.

[db8us]

As i heard....

when having a normal breathing pattern the unit was NOT venting any gas, when breathing hard the vlavle was "flattened" andy then venting "some" gas

[madmole]

To me that valve looks like its had hot water on it, maybe he has been a bit enthusiastic on his cleaning

Shame he had no PO2 monitor, especially as he had a second RB with him

ALWAYS know your PO2!!!! and that goes for ALL semi closed and the RB80. Anything thats mechanical or electrical will eventually break

As for a buddy, how many times does it have to be said and the fatalities mount up. Dive alone, die alone

[caveseeker7]

madmole once bubbled...

According to the LKA press release BOTH RBs had damaged check valves.

[db8us]

Yep, both valves were damaged.
It looks like the manufacturer did not make enough tests prior to sell the unit, or just took cheap stuff :(

@Madmole
we always use a Po2 Monitor when trying out things and on the first maybe 100hours.
On long exploration dives we leave it at home, since we stick to listening and feeling the machine work, as there is no time checking Displays and i do not hear the alarm.
The sensors show stupid values after 10hours....

[madmole]

mmmmmm low or high PO2 doesn't make any noises and feelings either!

and if the O2 meter tells you the PO2 is wrong after 10 hours, which is wrong the PO2 meter or the user!!!!

I get a physical symptom when My Land Rover runs out of Diesal, and I can swap to the secong tank, but I still have a gauge on the thing and a yellow idiot light

We are all human, we all make mistakes, even the best maintained and checked kit can fail. Stack the odds in your favour and KNOW YOUR PO2

Yes, other Passive SC breathers have better valves, but they still have this single point of failure (and others). What happens if its leaking just a little, just enough to lower the PO2 below what you think. The unit will still behave the same, and vent gas when you expect it (just a smaller volume), the dive will go fine and then you surface and BINGO

We already know the Passives have a problem on the surface and shallow surfacing, hence most folks go OC at the surface (plus the breathing resistance is too high when upright waiting for the boat)

if your sensors "give stupid values" its sounds like moisture on the cell face.. sounds to me you need a better place to put them to keep them dry rather than losing them.. also rising co2 will give cause "funny" values, the po2 will be lower than expected, as long as its not too high only increased breathing rate will be noticed, and the body can withstand this for a considerable time. its not until the co2 reaches a critical level when things start to go wrong..
the constant venting of an scr can really hide co2 issues, keeping them to a tolerable level by the body when something is really wrong.

[db8us]

If i am shallow or near the surface, i do not need a breather.
I only use it if itīs advantages outweighs the disadvantages.

Here in a local lake (20m depth) i often see divers doing 40Minutes with an YBOD or Draeger...
I prefer OC then...

During exploration dives i think one is not able to constantly check "displays" and i can not hear the Oxygauge-Alarm ;-(

[madmole]

Well, for most YBODS owners the advantages do outweigh the dissadvantages

Warm gas
No noise or bubbles
No dry throat
Nice smooth natural breathing pattern
No concerns on gas duration
Able to standardise one set of bouyancy skills rather than swapping between RB and OC floatation
Perfect Nitrox/Trimix mix for depth, therefore longer duration or less deco

Heck I even use mine in the pool

disadvantages, mmmm
I have to pack the sofno and prep the unit
Its bigger out of the water than a 12 and reg

Youre the 4th or 5th RB-80 user I've talked to who finds that their unit is not suitable for shallow water use, is this a design fault or a user problem? having to swap OC and RB skills on every dive is complicating matters, and what if I have to resue you, I now have to do an extra check to see what the hell you are breathing and do I need to close your loop or not. Doesn't sound like a simple solution to me, most unDIR

As for not being able to flip up a handset and check some numbers every minute or so, thats rubbish, course you can do it easily (trained and practiced since dive 1 on the unit). Dont you check your tables, bottom timer, contents guage etc during your dives?. How do you check and listen to the RB-80 to make sure all those valves and injectors are working fine and bubbling when they should then? At least the YBOD, HH etc shout/flash/Shake loudly if your a complete prat and miss the obvious.

Dont get me wrong I like the RB-80 and think its a good unit. But its not the ONLY unit and its certainly not the most suitable unit for the way most folks dive. If its the tool that you choose to use thats fine, but consider that not everyone dives the same as you and that cost and availablity are also important factors in the choice of unit. Just consider yourself a Mac user when the rest of the world are using PC's

[anthony12]

I have never dove the rb-80, and am sure it is probably a fine rig. I have to wonder when someone says a RB is not suitable for shallow dives. I think they are perfect for shallow dives. Your body becomes the only limiting factor. If your warm, have a nice current to ride-I've stayed down for 3hours a wack taking some unbelievable photos at 70' or less.

As for the RB-80
1.) Its way to expensive
2.) Very few actually being dove
3.) No included PPO2 Monitoring

Like I said before, its probably a great unit. But, its way to expensive, not many people diving them, and no incuded PPO2 monitoring. As a single father cost is very important and PPO2 monitoring is even more important. If the RB-80 is your choice then I'm sure you put a great deal of thought into it and its the right unit for you. After alot of research and a couple tests of other units I chose the Inspiration because it was quite simply the best I could afford, the most units produced, and the fact that I was able to dive one before I emptied the bank account.

I've done 10m shore dives on my Inspiration and couldn't think of switching back to OC. To hang just above the grasses at 6m with perfect buoyancy, breathing warm/moist air and just watch the fish swim around, fish eating fish and they get really close without them damn bubbles.

While I did buy the Inspiration for deeper dives (which are fun too :) ), nothing wrong with a nice shallow dive on a CCR. As per DIR, diving the same equipment is goodness.

How deep do you go before switching to your RB? Or do you start the dive semi-closed and just end it open, blow what's left once you know you won't need it?

The Dräger is sort of made for those kinds of dives. The ones you're doing on your RB80 and lots of CCR divers do shouldn't or couldn't be done with a Ray or Dolphin. As for the duration at that depth, could be mix (on SCR), boredom or stamina. Not everyone is in, and into, top shape.
However, to stay proficient at diving, especially CCR diving, you have to practice. I've seen people do the same with double 12s and stage in quarries. Invites ridicule, but you gotta keep practicing somewhere.

On an RMV-SCR you shouldn't have to do it constantly. However I'm sure you could master the task of checking if you felt the need to do so. As for the Oxygauge, as well as the previously mentioned odd values, it's only one sensor. A tripple display with as many sensors it the way to go ... .

We talked about that before. The RB80 was developed for deep cave penetration, DIR style. For that it works, obviously, rather well. That doesn't in any way mean the rig can do anything that coudn't be done with a CCR. The butt-level bellows works well when horizontal, which is where they spend most of their time. If it works for them, it works for them. Doesn't mean it works for you and me. As JJ said in a thread (bouyancy section)

GUE was never about training for all divers any more than Halcyon strives to be about equipment for everyone.
The RB80 is Halcyon gear.

They were talking about the same equipment and configurations for similar kind of dives and among team members. Do you really think that every DIR-caver hauls twins, stages, scooters, reels, lights and if, they use one, an RB80 or two on every dive they do?:confused:
Add-ited: Also, DIR means not to take anything you don't need, which I'm sure has a highter priority than taking everything you need on your most challenging dive everytime you go for equipment-sameness sake.
Besides, when using any RB other than the 80 you're already doing it all wrong. Might as well enjoy the shallow dives with your CCR. :D
(End of Edit)

The RB80 seems to do what is was designed for rather well, judging by the dives done in FL and Europe. But it has limits and negative points just as any other piece of equipment. May that be price, availability, breathing comfort, size, lack of decompression advantage. If any or all are important, use something else. Whatever else it is, I'm sure it comes with plenty of disadvantages, too.

It would not say "unsuitable", just "unnecessary".
I would not bother filling it, etc, since you have to be as anal with pre-dive checks etc as doing a big dive.

Of course i COULD check them every Minute, but this would take attention away from the cave, buddy, etc and i do not want to stop scootering, so i decide not to check it !

I totally agree on that one. I use the RB80 for cave-exploration and for some deeper lake-dives and i a usually do not fight against other units, since i do not have experience (enough) with them.
I just wanted to point out, that saving money and going for a cheap-bad-copy might kill you and this is what this thread is about.
e.g. i said on exploration dives i would not use an Oxygauge, but I COULD, because the port is there (and on the first 4-5 exploration dives we had it in)
On the EDO, they even saved the money for the port to plug it in.

Michael

[db8us]

@Anthony:
about the price: It is not cheap i agree, but the swiss tried to make one cheaper and so they took cheap materials instead of Teflon-coated alumnium, Stainless steel, Darling-hoses, spring-loaded scrubber.
They even saved the Oxygauge-port and an Overpressure-valve on the switchblock. This is stupidity, i totally agree with you !

@caveseeker:
about the training, i agree, but we quiet often do longer cave-dives and so we stay "sharp". Also we use it sometimes shallow for breather-workshops.
We require our team-members to be "retrained" every year, of course thats for free, since we are not commercially interested.

About the checking and hearing:
You hear the gas venting from the breather and after every 2-3 normal breaths or every deep one you hear the hissing of the gas injecting. The more Helium and the deeper you are the better it is.
I have no clue if you would hear it on an EDO04, cause the injectors are sitting in plastic, which does not transmit the sound to good.
By they way, the amount of force need to trigger the EDO is 3 times the force that i need on my unit !

If the EDO would have been a working copy without design flaws i would have no problem admitting it is DIR !
But never we would compromise safety against saving money.

Again: I only speak for myself and dives of our group.
If one wants to do shallow stuff on the breather because it feels good i can understand it. But i would rarely do it.
I did some shallow dives on military oxygen-rebreathers, etc, but i still would prefer OC for the "letīs jump in"-dives.

[KentCe]

db8us once bubbled...

People make that statement, but its always false. We always make safety trade offs to save money. Even NASA. Even airlines. Even when we buy cars. Welcome to the real world.

The key term is "compromise safety". Very subjective. To some not having a deco chamber on the boat would "compromise safety". (How many lifes could of been saved if every dive boat had a deep diving deco chamber on it?). To others, saving money not buying a second dive computer would compromise safety. Then down to the simple metal vs plastic for clips.

Life is more about managing risks within our incomes range.

OK, you are right, but would you buy a car without airbags and buckles and safe letīs say 500Dollar on a 30.000 Dollar car ?

If we we would talk about either 100 or 10000000000 i would agree.
But of course this is also up to everyone.

It is like the redundancy question.... This guy was diving solo, but with a double-rebreather.....
Where was the redundancy of a divepartner who could have just stand him up ? He drowned in 6feet.....

... I believe the stock dashboard contains to many gauges. :wacko: Gas contend in the tank is of course allowed as a necessity. Probably needs to be taken out of the dashboard and clipped to the left hip ring of the harness.

The tach has to go. When Driving It Right, one drives by ear, just like the RB80. If something's broke, you can hear it! Same for oil, water and the other small stuff.

What confuses me is the speedometer. It usually contains the trip counter, which is important ... can't really lay out line on the freeway. On the other hand it also, and unfortunately rather dominantly, displays the speed. That is completely unnecessary, and might not be acceptable. There are mile stones (or in Germany kilometerstones), and I'm sure Waldy wouldn't drive without his timer. Therefor it is safe to assume he, as all his fellow Drivers It Right, calculate the speed on the fly. Gotta plan your drive and drive your plan.
So I'm not sure if the speedo can stay or needs to go.

Now that I think about it, probably better go. All the idiot lights too, of course, warning lights are definitely not Driving It Right. That way you can throw out the entire dashboard and streamline the interior! :D

Yes, unfortunately Kevin started off very well sending me these, but lately they have dried up

But they do have Hammerheads shipping with the new controller Algorithm (that I wrote the prototype of!!!) and its working really well. Much tighter Set point that the original Inspiration, down to over 100m so far

They also have the new selectable GF software out.

New hardware out in next week or two as well, this allows the use of ANY AA form factor battery

As for girlfriends/other halfs and Landies, dont do it!!!!! its so much fun to drive and their are even more bits and bobs to modify it with that what little money is left from the RB will definately dissapear!!!!! :D
I understand what what you're saying, but the thought of going to and from divesite's without straps and ropes is tempting. Look what I got to work with.:rolleyes: But it's the most fun for the buck, naaa, for the dime you can imagine.:D
