Mine flooded when the nut on the opv failed inside the counterlung 2000 feet back in a cave. Had nothing to do with an o-ring.

I quit the revo long before becoming an instructor.

Anyone who says the Revo breathes like every other rebreather is either a filthy liar, never dove another rebreather, or delusional.

Can you scooter straight down to 200' and have the adv keep the loop perfect and ppo2 perfect on a revo? You can on an Optima.

You think build quality is good? Maybe look at a liberty where every piece is CNC machined. It's put together looking like a Ferrari instead of a Yugo.

Some of the Revo is innovative, like dual scrubbers and RMS. But that innovation isn't necessary.

I say these things because I put over 1000 hours on three different revos I owned. I used to defend it just like some of you will. Then I tried another rebreather. In fact, my first experience on another rebreather was pretty much an $8000 bet I lost. After diving the Revo exclusively in big deep caves for years, someone put me in another rebreather brand and bet me I'd change brands the next day. I'm still pissed I was wrong.

Free try dives are the most expensive by a wide, wide margin.
 
Superlyte27, let’s look at your profile shall we, a technical diving instructor and salesperson based in Florida who sells the Optima (by the way the web link to underwateradventures does not work), where in that market the rEvo is a pretty major player and competitor, so we should first acknowledge this is the position you come from, you probably think it is in your interest to deride the rEvo, though it is rather unbecoming of you. I think that generally puts your comments into perspective, ie a bitter and twisted instructor and dive gear retailer.

As for your claims regarding build quality, just how do you suggest the case containing the lungs be constructed, CNC machined out of block titanium, stainless, or maybe aluminium, no that would be just ridiculous and most inefficient. Just because something is CNC machined does not make it superior. Just a note the manufacturer behind the rEvo in Belgium are specialists in precision machining and manufacturing, I think they would know their **** when it comes to the best way to manufacture the rEvo.

Your comment about WOB is just the typical unfounded BS that someone with a vested interest in diminishing the rEvo performance would come up with and is just crap, and you would realise it if you were completely honest with yourself.

Me, yes the rEvo is the only rebreather I have owned and trained on, and the only rebreather I intend to own, I can't afford to be upgrading to the latest and greatest every few years after all diving is just a recreational pursuit for me, one which I very much enjoy and have no intentions of ever becoming an instructor. I have had my rEvo 5 years and approaching 400hrs on the unit, mostly diving and exploring deep reef and wrecks. In that time I have not missed a dive because of the unit or hand any major incident involving the rEvo. I have now had the opportunity to try a number of other rebreathers, dived with other rebreather divers diving other units and pretty much had a close look at most of the units produced by the major players, based on this I am very happy that I went with the rEvo 5 years on, and if I was making the decision today I would still get the rEvo. So I am pretty happy with my choice, it’s not perfect there are a few little things here and there I would like changed but they are not biggies.
 
Quit talking until you've tried another rebreather. You simply don't know what you don't know.

By the way, as far as being a sales person and instructor...
That occupies 1% of my time. When I teach, it costs me thousands of dollars, because that's what I lose each day not doing my real job. So, I'm very selective of who I teach.

The revo sucks. Actually, sucks hard (because of the wob). It's okay that you don't agree with me, but when someone finally does convince you to try a better rebreather, come back here and own it. Just like I had to do when I finally figured it out. Until you've been on any other unit for a real dive, shut up.
 
When I met my wife in 1996 she couldn't quit talking about how awesome her car was. She said it was the most awesome car ever and super fast and just the best thing on the road. Now at that point I had owned a 69 Camaro, 69 Mustang, a 69 Firebird, a Porsche 944, Maserati biturbo, a Corvette Stingray LT1, and about 20 other awesome cars so I knew her 1984 Mazda RX7 was an absolute piece of crap. But she had no frame of reference because it was the only car she had ever had so she didn't know that her 1984 Mazda RX7 was total junk. Today, just recently we got rid of her 2016 Camaro. I drive a Cadillac Escalade and in the next couple of months we're buying her a 2018 Corvette Z06. You think she's got some frame of reference now? Of course she does.

You're in the same boat. Instead of a piece of crap purple RX7, You're in piece of crap yellow Revo. And you defend it with a tenacity, all the while looking like a goober in a busted RX7 with no experience.

I don't know superlyte. Never even exchanged a PM with him. But, I've read a lot of posts from him over the last 3+ years.

None of what he said about the rEvo came across (to ME) in the way you described. At all. It came across to me as a guy with a lot of experience with the rEvo and with other units, who has an opinion that he didn't sugarcoat.

I'm not saying that he was perfectly accurate in his statements. I have no basis for judging that. I'm just saying they seemed like honest assessments, not salesman BS. And from a guy who appears to have the credentials to make credible assessments on the things he was talking about.

Just my $0.02.

This, on the other hand.... Well...

I may be starting CCR training soon. On a rEvo. It's just a matter of getting it scheduled with my shop. I welcome the opportunity to get certified on the rEvo, since I will be using a unit the shop owns during my training. But, when it comes time to buy something, superlyte's comments will definitely weigh into my decision on whether to buy a rEvo. Not that I will just blindly assume what he said is correct. But, he has given me a lot of things to think about as I learn the rEvo. Things to look at on the rEvo and compare to other CCR possibilities.

I reckon we were typing at the same time. This post just made me giggle. And hate you a little bit. I have wanted a Corvette for a long time... Please tell me she is getting a manual transmission.... Or, maybe getting an automatic would make me less jealous... *sigh*
 
So... The Z06 dropped $25k this year because of the ZR1. We did our build at GM and the automatic transmission is a faster car.... So I was really struggling with it. But then I was told the automatic was a $2100 upgrade. We'll be sporting the 7 speed manual. :)
 
If the auto were paddle shifters with a DCT transmission, I might consider it. But, even if it is faster, I would rather have a manual than paddle shifters with a conventional auto I'm stupid.

And I'm still pissed off that they changed the Z06 to using a supercharger and being heavier, instead of being lighter than a regular Corvette and making more power via more displacement.

So, anyway, are you going to tell us (I don't recall that you did, but I might have missed it) what is your preferred CCR now?

EDIT: Never mind. I gather it's the O2ptima. Have you tried the new BMCL that they were showing at DEMA?

Haha, let's talk about that privately. I actually have a few favorites.
