How well does the rEvo travel?

In the BOV or no BOV debate there are of course a mix of revo divers some who have and some who haven't added an after market BOV.
For those who haven't I can't help wondering how many were influenced by the fact that the unit they bought didn't come with one as sold, either because they just dived the unit for X hours and liked it or because they took the lack of one as recommendation?

Could those who were undecided on the BOV topic have rationalised one as unnecessary in a 'I made the right choice when buying my unit' kind of way?

Naturally there would also be those who were already in the No BOV camp so for them the lack of one on the revo was a non issue when deciding which unit to buy.

I am just speculating. What I wonder is how people who buy units that come with a BOV as standard and later remove them? Seems less but I don't know. I am still an OC diver who likes to lurk and read about these machines.

Started with a Bov, then removed it :)

What's the plan to deal with retained C02?

Find a lot of revo divers think they are immune from C02 due to dual scrubbers. In reality I agree that scrubber breakthrough or channeling is practically irrelevant on the unit. I have yet to see any reasonable explanation on retained C02 however. When you listen to the diving medics the scary one is retained C02 considering how much of a subconscious process it is in some people. It's also hard to test for.

That's a nice discussion, not immune for sure !!! But i guess we don't want to hijack this thread so maybe open another thread for this or use the search engine ;)
 
For what it's worth I own a rEvo II mini; I bought the mini specifically because it's travel friendly and I've been very happy with it. Actually bought unit from mmarcoux's wife when she upgraded to a micro.

It's been on buses, ferries, planes. The unit easily fits in overhead compartments. I've carried it on airlines 3 times since purchasing it last year. Last time I even brought it on plane with tanks attached to unit (without valves) and full scrubbers.

I will say that on my last trip Mexico customs (Cancun airport) gave me trouble, not because of the rebreather itself but because I had tanks with it; They didnt care about the rebreather. Don't travel with tanks on it if you can help it or check tanks separately in another bag. I eventually had to get a Delta supervisor to explain to Mexican customs that tanks (without valves / unpressurized obviously) were allowed on the airplane.

I don't have the neoprene cover for it but I use a grill cover (also suggested by mmarcoux). It works well to cover it but doesn't really provide a lot of protection in the event you actually did have to check in.

The only slight downside to warm water diving with the rEvo II mini (stainless steel) is it a bit heavy; As in it's a very negative unit. I actually wore a 7mm to try to counteract. In cold water with a drysuit and thick undergarments I use 8lbs (sorry..metric I mean ~3.6kgs). I believe the rEvo III micro is lighter (titanium) so it should be less of problem
 
I've read enough (and asked about on another forum) to decide I want a BOV. Yes please! :)

Another question regarding the rEvo Micro - how easy is it getting parts? Both throughout Europe and worldwide?
 
When I ordered something I usually get it the next day, maximum 1 day in between.....but I live in Belgium ;)

From TDF it looks like you are saying you now have an OSEL BOV?

P.S. Your English is good but in case it helps the correct past tense for send is sent not sended.
Many idiosyncrasies including irregular verbs in this language I am afraid
:brickwall
 
Yes, removed the shrimp, loved diving with dsv ( simple, light) bought the ALV bov because I was very curious about it. Still in the process off making a good adapter for my rEvo , dived it already , breathing is very good. I will do a write up when I dived it a little more.
For the moment I'm back on a normal dsv for simplicity.
The alv is definitely the fastest way to OC , you just pusch your jaw forward.

Thanks for the correction on "sended ", I can't learn if nobody makes corrections . :)

What BOVs can be fitted to a rEvo?

As I have read rEvo loop circulates right to left not left to right so either you need a BOV that is designed R-L like the ALVbov or one where the direction can be reversed (I assume this is the case for the shrimp?).

Will be interested to see the report on the ALVboc. Being new to all of this I am not up to date on the full APOC / OSEL / Brad Thorn story but the threads that touch on it can get quite firey.

As you mention the ALVBOV is a simple one for one replacement with the stock rEvo DSV and hoses. With the right adapters you can even make use of the OSEL wide bore P-ports which make disconnecting the loop a breeze.

Not sure what report your after but if you want the WOB testing reports for the ALVBOV see:
http://www.deeplife.co.uk/or_files/DV_DL_ALVBOV_Breathing_Params_A3_100318.pdf
http://www.deeplife.co.uk/or_files/Fault_Study_CO2_Bypass_110314.pdf
https://www.opensafety.eu/datasheets/ALVBOV_40m_75lpm_air_081014.pdf

For what it is worth following the significant number of unexplained rEvo fatalities that have occurred. OSEL took unusual the step of reaching out to Paul at rEvo and offering the ALVBOV to rEvo at a significant discount. In order for the ALVBOV to be offered as a factory option on the rEvo to improve users safety through having a BOV rather than just basic DSV. It would also enable Paul to reduce the rEvo's total loop WOB over the stock DSV, offer better quality & shorter breathing hoses and ditch the loop weights.
At some point in the future OSEL will publish WOB data of the ALVBOV fitted to the rEvo and potentially a number of other units. Just to show how easy it is to upgrade the units performance whilst improving safety at the same time.

I would be very interested in seeing those WOB numbers. I look forward to the OSEL publication.
 
it is always easy to talk BS when people cannot and are not allowed to talk about things.

to my knowledge, and to the people involved, that have to know, there are at this moment no 'unexplained' rEvo fatalities: if people follow exactly the procedures as lined out, regarding pre-dive and pre-jump checks, cell replacement policy, and if medical issues would not exist at all, there would have been zero rEvo fatalities till now!

telling people that if we buy 1000 euro BOV's, and install them on rEvo, (and this way violate the CE approval of the unit).... is just bad taste!

Fair cop. I had thought that a number of the deceased and their rEvo's had not been recovered and had not even heard a whisper of formal accident investigations having taken place.

Paul, the ALVBOV would only be a 1000 euro BOV for the rEvo if you added a 100% markup.... If your customers buy this safety and breathing performance upgrade direct from OSEL it is quite a bit under 1000 euro and includes breathing hoses and P-ports for easy install. Customers just need to source adapters for their particular rEvo as there appears to be no standardisation on ports to the rEvo CLs. As I said OSEL offered it to you at quite a discount to offer your customers improved safety with no effort needed on your part.

Oddly the ALVBOV when fitted to an rEvo is the sole component that meets the CE standard EN14143 be it 2003 or 2013. You would LOWER your units WOB by offering it and if RINA complained about that, they would have to be the first notified body to ever do so for a rebreather. https://www.facebook.com/1512989548...298954899613/1176347012394797/?type=3&theater

that is because you just make things up when you have no data!

you write: ' ...following the significant number of unexplained rEvo fatalities that have...'

it's like me writing: ' ... following the significant number of unexplained disappeared APOC divers that ....'
