    Which eCCR?

    Ah well, here goes, my first post on RBW.

    After 46 years of diving OC, I've decided to take the herculean leap to eCCRs. I've done a try-dive to 20 metres on a Poseidon VI in Indonesia and enjoyed it immensely. The only downside was the heavy mouthpiece. However, it was this experience that set me on my course for a eCCR.

    Buying a RB is not straightforward. It's not like walking into a high-street shop and browsing the selection on sale! To all you guys out there with at least one RB, I'd appreciate your recommendation of what you think I should be looking, or, what I definitely shouldn't be considering!

    My criteria so far - a) ease of owner maintenance/servicing, b) ease of dismantling for overseas trips, c) no immediate plans for trimix and, perhaps most importantly, d) reliability.

    I haven't ruled out a Poseidon Se7en but I'd welcome any advice on anything else.

    Thanks,

    Robin

    posiedon mk6/seven

    Re: Which eCCR?

    I dive a Poseidon mkvi, just upgraded to a seven. Just waiting on it's return from Poseidon. Good thing about the seven if your not thinking trimix at the moment is ease of upgrading. Change the battery and completely change the unit. If you were thinking more trimix route if probably choose something else but for rec and 48 trimix definately seven is a good option!

    I recently moved to CCR because of the logistics of OC at the depths I was diving. Aside from (c), you and I have similar criteria and I went with a rEvo hCCR. Because a good rEvo II mini came up at a great price, I bought it and got started on CCR probably a year sooner than if I'd waited to buy my ideal unit brand new. If you're looking at a new one, I'd get the Micro III titanium or an expedition hCCR.

    In terms of ease of owner maintenance/servicing, I was able to completely break the unit down into its component parts on my own before class to troubleshoot a small leak at a counterlung connection that was causing the unit to fail a bubble check. Fixed the leak, rebuilt some p-ports, and then I put it back together without too much trouble and it was ready to dive (there was a little last minute help from Jason Fisch the morning the class started, but only because I wanted to get new cable glands on it even though the old ones weren't leaking). The only things I didn't mess with were the Clippard manual addition assemblies (which new rEvos don't have) and the lungs to scrubber housings connections (trickier than the lungs-p-port connections). Most of the upgrades I'm aware of (revodreams, WOB kits, waterproof solenoids) are offered as user-installable.

    Breaking down for travel is pretty easy...I pull the tanks, and put the whole thing in a carryon bag. A micro TI version would be even easier.

    Reliability...so far, so good. It's surely a simpler unit than the Poseidens are. I won't comment on relative reliability because of my limited CCR experience, but one of the reasons I picked a rEvo was because it's simple and that tends to translate into reliability.

    Given that Poseidon has one of the smallest BOV on the market, the only way to go lighter is to choose a unit without BOV and for recreational diving or light technical diving many divers like to have a BOV for easy OC Bailout.

    The Poseidon has a 2 year service interval. In terms of user maintenance it is pretty straight forward. Not many parts.

    Dismantling the unit is quite easy and it is travel friendly. Loop hoses and T-pieces in the canister and the e-module in the carry-on.

    Trimix can be added as you go, by getting the Tx battery.

    I have had my unit since 2011 and have done approx 95 dives, had some big issues with cold water diving, but since mid 2012, the unit has been working flawlessly for about 85 dives.

    But as always, you need to understand your unit and the functionality. The automated predive check might fail from time to time, sometimes without obvious reason and sometime due to user failure. But it is all about trying to keep it safe.

    The Poseidon is a great unit, probably not the best, but certainly not the worst either.

    Hi Robin,

    Nice to see a local (I'm in Dorset) here... as for recommendations everyone will likely just recommend their own, very few people have dived enough units to have a wide enough experience to recommend (me included)

    However- If I where in the Market and looking for a versatile ECCR and like you based in the UK my shortlist would be-
    1. JJ-CCR, Lead instructor on your doorstep, leads the way in simplicity and reliability, can be stripped to fit in small suitcase and head in hand luggage, will accept any tank size you find at your destination, a veritable swiss-army knife.
    2. Inspiration Vision, Also on your doorstep (Cornwall) for back-to-base servicing and repair, massive history of diving with lots of experienced users and 3rd party parts, travel frames etc, often imitated, rarely bettered. Some negative press on forums because the most recent version is quiet old now... there is a reason why they haven't changed it- it just works.

    Personally- I would avoid units manufactured in the Americas due to servicing, spares and the language barrier

    IMO the Poseidon 7 is too new, you should look to buy units that have been out for 2-3yrs and the niggles ironed out, manufacturers have a habit of releasing CCR's too early and letting users do the final testing!
    In the future the Sentinel might be an option, Vobster's have just taken over manufacturing and might make a silk purse out of a pigs ear but at the moment the product isn't worth considering as you require travel and reliability!

    With regards the heavy mouthpiece- most CCR's mouthpieces are heavier (in air) than a 2nd stage regulator but the hoses should be adjusted to provide a degree of "lift" to counter that, underwater the mouthpiece can be setup as weightless
    Some units come with a mouthpiece retaining strap to hold them in place, I have one and its great- you don't need to hold onto it with your teeth at all!
    In Summary- don't let the mouthpiece issue hold you back.


    Remember- Advice is worth what you pay for it, this advice was free, treat it as such

    Re: Which eCCR?

    Robin,
    I'd go with Ben's recommendations but if you go for an inspo get the back mounted counterlungs, or at least make sure you budget to get a set,
    I also suggest Looking at the Revo, the standard is a little big for comfortable travel (I still get mine in a suitcase ok), but the Mini and Micro's whilst still not coming apart much are easy to fit into a suitcase and are bullet proof.
    I've dived a JJ, and I dived an Inspiration for 5 years, and I currently dive a rEvo. I've dived all 3 enough that I'd dive any of the 3 to the limit of my training after a couple of dives to reacquaint myself with the units I don't currently dive on a regular basis.
    In my opinion the rEvo has the edge over the Inspiration, but had AP released the back mounted counterlungs at the time, I probably wouldn't have bothered to swap from the Inspiration to the rEvo.
    The rEvo electronics are more modular, it's perfectly possible to carry a spare fischer lead and computer and should the electronics fail swap them out and keep diving (never had to do it yet, but my 2007 rEvo II standard now has the rEvodream-P and the Shearwater hCCR kit on it which didn't exist when it was originally released).
    The inspo is easy and quick to get spares and service on, JJ's I've not got experience of the service for.

    The other consideration is do any of the people you dive with already dive CCR? as if your diving with a group, it makes sense to dive what the others already have experience of keeping running and you can pool spares.

    My final word of warning is that a Sentinel is probably not what you are looking for as a first rebreather, They are bulky and heavy if you are trying to travel with them, and they have lots of complicated electronics that don't have the best reputation for reliability.

    The P7 is definatly not a owner maintinance unit

    rEvo is excelent but for easy travel you want the micro titanium or just about the Mini but I had the SS mini and that was a bit of a sod to travel with and was too heavy for a wet suit.

    JJ is so reliable I dont think owner maintinance is worth worrying about but if the head goes it is back to base unlike the rEvo. However its top trumps for travel and its a joy to dive.


    Personaly id want a Golum Shrimp on both and for the rEvo for UK diving you will need a stand

    rEvo has a HUD but i dont like it and much prfered the Shearwater type display.


    Which ever you decide I have little doubt you will be very happy with your choice.

    As for other units currently available?

    A bit of an odd one but a Inspo with Narked @ 90 head on it in a G box is a great unit if you can put up with front mounted lungs. However thats Second hand only as they no longer make the heads.


    Aside from that theres nothing else currently available id be interested in in terms of an ECCR.

    MCCR id get a KISS

    Just to set the record straight here, The Poseidon 7 is the Poseidon MkVI without the niggles... ;)

    The Se7en is in no way a new rebreather, contrary to what most think. Refined maybe, but new? Nah, It is the same concept as it always been.

    Whatever you choose, there will always be a downside. There is no such thing as a perfect rebreather ;)

    FWIW- I know this but IMO the Mk6 had So many niggles they should have skipped it and started again! So the 7 is their first attempt at a rebreather

    WILDLY Off topic though... sorry
