Some CCR help

[tienuts]

Those are some strange numbers - what kind of bailout bottles cost $562 each?

I used new retail prices for all the figures.

Again please tell me how I am not knowledgeable about the rEvo. You want to know why I am, I almost bought a rEvo when during my exhaustive search to buy the perfect unit (I know that is questionable either way). Plus I have friends who dive them, so I have heard their shortcomings straight from the horses mouth.

Since no one else has yet, I'll tell you - you are not knowledgeable about the revo. There is A big difference between Internet diving and real world diving. How many ccr hours do you have? Go get certified on 3 or 4 units, put 50 hours on each and then come back and talk.

There was a time when most RB divers "thought" that, but the facts - over the last 3 to 4 years, from my personal observations and from all the forums I read - don't seem to bear it out.

I used to be a huge fan of 4-8 airgas stuff and say the same things you said here. Until we had Paul R test it in his ANSI machine - it turns out 4-8 is much less effective than sofnolme 8-12. I'm not saying it's less safe sorb, but pound for pound it is certianly less efficient. Scientific testing goes much further than personal observations.

I think I have enough experience and hours to say with authority that the rEvo is NOT perfect.

Hell, i have no experience and hours and can say with certainty, that the Revo is not "perfect".

[tienuts]

No rebreather is perfect, including the rEvo and I never said that it was. But it certainly isn't a 'gimmicky piece of crap' as someone stated.

Sitting back and formulating all your opinions from comparing specs is a far cry from getting real world experience diving to see what really matters in a unit.

It always makes me laugh when people knock something they've never even dove. It's like me saying diet coke tastes like ****, but I've never actually tried it.

True, but it only takes one sip to know for sure, not 50 hours on three different diet sodas

I have almost 200 dives/hours on my rEvo now - never an issue with it.

If the can says it contains artificial sweeteners it doesn't even take a sip.

Forrest, I'm not sure if you're making a joke or not, but if you're not, I disagree with you. In the first 20-30 hours you're still figuring out the nuances of the unit. You have not had a well rounded experience on any piece of gear after a 'try dive' or even after your first few dozen hours. This includes some of the various 'concerns' others are raising.

I know bias comes with ownership of a particular unit. Most people will defend their $10,000 purchase, because they need to

My point is, that if you don't have even some basic experience with something, you don't have any business commenting on it. For example, I have never dove Telford. If someone comments in a thread that Telford is a wonderful dive, and I come along and say "No Telford is an awful dive," just because I read that on the internet, what would you think of such a comment?

It seems like an absurd point to even debate.

when did Paul test sofnolime 408 against sofnolime 812?
All of the results I have seen from him he has never published a sofnolime 408 vs a sofnolime 812.
He has published sofnolime 797 vs other manufactures with those sizes.
but I have never seen him test the different sizes of sofnolime against each other.

we have even asked him to do a head to head of the 408 vs 812(797) and he declined

I have never seen a test comparing Sofnolime 4-8 with 8-12, but Airgas SODALIME 4-8 mesh was tested by Paul R, and here are his findings.

“ok, here is the result of the belgian jury.

the sorb I recieved (has no name on it, was repacked in double plastic bags) can clearly be catalogued as 'low performance sorb'

using a rEvo III standard

under CE conditions: 4°C 40m depth, air ventilation 40l/min 1.6l CO2/min

breaktrough 5mbar 65 minutes
breaktrough 20mbar 82 minutes

under exactly the same conditions there is granular sorb available that does consistently > 170 minutes till 5 mbar”

cheers

While far from the whole story; it appears the Airgas Sodasorb offers less performance than the Sofnolime stuff.
