as before again, trying to overwhelm people with a train-load of pseudo scientific explanations..No real news here!
Why no delivery time for the ICCR? The units delivered are good but not complete (for iccr EAs). The component delivery issues should have been solved by now or at least some idea given as to the continued delay! If you buy a unit you will have to add expensive 3rd party monitoring to make it dive-able at present if you accept a split shipment. This cost is then a liability when/ If the ICCr loop turns up. If they are not going to be able to deliver the ICCR i wish they would say so and everyone could use the 3rd party monitoring package and be done with it.
The pricing is getting silly, i am sure the other manufacturers are all pleased about that and smiling to themselves with some relief. It is no good crowing about delivering half the product. The news letter should have been about what they are doing to deliver the product they set out to produce.
Paul, I think that last news letter has helped clarify things for those that might have thought of this unit as a viable option at one time.as before again, trying to overwhelm people with a train-load of pseudo scientific explanations..
all the BS about the VWAI, when everybody knows that this does not form the real limit for endurance, but the 5mbar PPCO2
and leaving out the spindles.. well I suggest you all try to do this on an 80m dive, as it is AD-approved
and it goes on and on....
good luck with it
Whats bodge about OSEL supporting the adaption through a quality dive equipment supplier of what looks like a Shearwater solution on a CCR, don't JJ, Titan, ISC, KISS and rEvo all offer the same elecs?It's a real shame that the concentration has again slipped from actually producing what they promised and into sniping competitors and bigging up a bodge solution to getting you diving this season.
What quoting the standard that their product meets and yours is supposed to?as before again, trying to overwhelm people with a train-load of pseudo scientific explanations..
Paul, so why not publish that as the CE test requires measured at the mouth against your rebreather?all the BS about the VWAI, when everybody knows that this does not form the real limit for endurance, but the 5mbar PPCO2
Interesting advise your giving to divers there. Wheres it approved?and leaving out the spindles.. well I suggest you all try to do this on an 80m dive, as it is AD-approved
Seems to have solidified it. If you want a currently industry standard PPo2 monitoring package on something with the performance and standard inclusions of the Apoc, NA90 looks like the man.I think that last news letter has helped clarify things for those that might have thought of this unit as a viable option at one time.
Brad, first try to understand what we are discussing here, then come back and try to participate in the discussionWhat quoting the standard that their product meets and yours is supposed to?
Or what looks like pointing out that the testing you have done is less then useful for actual CE certification?
Paul, so why not publish that as the CE test requires measured at the mouth against your rebreather?
Whats BS about it other then you don't appear to be doing it and its frustrating that your customers now know it?
Interesting advise your giving to divers there. Wheres it approved?
There being bugger all gas flow if the EACs plugs are left out due to the quality of the design and recommending diving without the plugs would seem to be very different things.

I'm not really sure what you are trying to defend here Brad?Whats bodge about OSEL supporting the adaption through a quality dive equipment supplier of what looks like a Shearwater solution on a CCR, don't JJ, Titan, ISC, KISS and rEvo all offer the same elecs?
Seems like they are producing what they offered just some are only now cottoning onto the spin-offs that are acheivable with it. The final NA90 solution on the Apoc seems pretty close to the original one shown at Eurotek just using a pod instead of the head which has to be cheaper if you want to go that way.

That looks like pretty decent image of a freshly made and wet iCCR pictured in the newsletter so OSEL seem to be concentrating on the target still.

As its just a case of unscrewing one pod and screwing on the other, fitting the CO2 pod and swapping over the ALVBOV to change to the iCCR isn't going to be hard.

You dont think its a bodge that they are launching their hyped product, only to fail to deliver on the ever so important SIL3 electronics.Whats bodge about OSEL supporting the adaption through a quality dive equipment supplier of what looks like a Shearwater solution on a CCR, don't JJ, Titan, ISC, KISS and rEvo all offer the same elecs?
Funnily what is quoted in the newsletter, is only the definition of what VWAI-wave is.What quoting the standard that their product meets and yours is supposed to?

rEvo-Daddy in another thread said:if anyone is confused, because of all the fog that has been created here, between the 5 mbar end of inhale and the max 20 mbar VWA, take a look at the standard:
chapter 5.6.6: scrubber endurance is given when the end of inhale inspired partial pressure reaches 5mbar: the end of inhale gas is the same gas as in the inhale lungs, as after the complete inhale breath, the mouthpiece is completely rinced with the inhaled gas coming from the inhale lung: you also see this in the breath by breath graphs
why sample the gas from the inhale lung: simple: to get far more accuracy: the max % you reach in the inhale lung at break trough is 0.1% at 40 meter, and 0.4% at 20 mbar: so we use a CO2 sensor with a max span of 0.5%, calibrated with a 5000PPM gas
in the mouthpiece, the % peaks to 10/20 times higher easely, so to measure there, we take a 5% or 10% span CO2 sensor
everybody knows that exactly measuring 0.1% with a 10% span CO2 meter is... bad laboratory practice
there is a second requirement:
chapter 5.6.1.5: max volume weighted inspired partial pressure of CO2 may never reach 20mbar, during any stated endurance: this is to avoid big mouthpieces
for normal sized mouthpieces, this is never a problem as when reaching the endurance limit of 5mbar, the VWA in the moutpiece is maybe between 6.5 and 7.5 mbar, depending on the dead volume and shape: so this one never limits the endurance
so all the fuzz about people that state false endurance because of sampling gas in the inhale lung, and not taking the VWA from the mouthpiece.... once again, all fuzz, nothing more....
See above. From all the info ADWard has provided I do not see it stated that he is actaully right in stating VWAI is needed, since meassurement is performed at end of inhale!Paul, so why not publish that as the CE test requires measured at the mouth against your rebreather?
Whats BS about it other then you don't appear to be doing it and its frustrating that your customers now know it?
we can always be wrong, but in this case I'm fairly confident we do it correctlyPaul could be wrong, but what was cited above does make sense, IMHO.
Is this saying that you should not use the Apoc for 2 hours 45mins unless connected to the C02 monitor? What is the recommended duration with out this monitor?OSEL Voiceover: Offcourse 2hrs:45mins is only for the iCCR with CO2 monitor, and we think ist *VERY* bad if you push your scrubber! Without CO2-monitor you should downrate your endurance (Pssst: People often get 5-6 hours from an EAC).
And we also put 5hrs of O2 in the tank.
We list many different combinations in the manual.
You as user therefor has to decide what we mean be safe endurance, but we consistently hint at 5-6 hours......
No hypocrites here, nothing to see, pass along........
55 minutes to the industry and military accepted 0.5 mBar loop CO2 breakthrough, if I remember correctly. If and when they ever get their CO2 monitor working reliably, we can revisit the issue. Until such time though, continuing to quote a 2.0 Mbar time is, in my opinion, bad safety practice (at best).Is this saying that you should not use the Apoc for 2 hours 45mins unless connected to the C02 monitor? What is the recommended duration with out this monitor?
