    At Beneath the Sea, I was told that the follow on model will be more in line with what is normally expected of Cis - Lunar, and expedition model with full deco and mix capability. I was also told that the rec model is upgradeable and can be refitted to meet those demands.
    This is going to be very interesting to say the least. As Caveseeker7 said, there is a lot riding on this not only for Poseidon, but for rebreathers in general. As far as I'm concerned, rebreathers are indeed the future of scuba and this would have happened sooner or later. Sooner appears to have arrived.
    Safe Diving,

    Not really. In both single tank (DIN/Yoke) the forward facing portion of the valve is solid metal. Not a knob. The knob is offset to the side. In the case of doubles, the isolator knob is central and forward facing, though it is somewhat protected behind the head of the diver. My thoughts here led more to entanglement than banging though. I wouldn't take this configuration into an overhead any sooner than I would a KISS Sport. Though I do know a couple of people who cave with the KISS Sport. And yes, I know that there is a trim issue with valves at the bottom, but I'd rather sort a trim problem than a potential valve failure or entanglement issue.

    I'd prefer some positive locks, but that shouldn't be too difficult to fit. I'd like to see the plenum without the tanks mounted though.

    Well, the WOB on some of the CE units hasn't been a lot to write home about. The Boros being a notable exception.

    Ooof! $6500? That's a pretty heavy initial hit if they want to mass market this baby. That falls in line with the manual Meg. Are we still looking at a class pricing structure of about $1k-$1.5k? Or is the "if in doubt, bail out" class structure likely to be cheaper?

    The ExtendAir sounds like a good idea to keep things simple and tidy, but $30-35 is a pretty stiff consumable for recreational divers.

    This may well turn out to be a good effort, but I still think the cost is a bit high to really penetrate the OW market. It would take an AWFUL lot of OW diving to justify the use of a CCR and $35/day sorb. Particularly when we aren't offsetting the price of trimix. For the OW diver who's spending a lot of time below 100ft, it begins to make more sense, but then we are back into that idea of deco. And bailout becomes a real factor. This may be just the ticket for photographers and videographers though.

    I wish them well with it though. I'm not going to DEMA so not sure when I'll get to see one. Maybe Jill will have one and I can see it at the next NSS-CDS event.

    I've been speaking with a Poseidon representative here in Mexico, they are the local RAID affiliated dive center here. Yesterday he showed me one of his Meg's and around the facility, and while looking at his stock he mentioned the Cis-lunar and showed me the life size cut out in the lobby I must of missed on the way in.

    When I returned home last night I went on RAID | Rebreather Association of International Divers and found it interesting how the elearning works - I did purchase level 1 - $100, this does NOT include the diving. Today he mentioned today he is working on that pricing and it should come in line with what they charge for a regular dive session.

    Tonight I did module 1 of the elearning to see what it is like - It is "Diving in General". I took the Quick Quiz in 2 and a half minutes and got 9/10 - it doesn't tell you what question you get wrong, that's not good. Was it how deep we can go at level one or how to properly breath while diving, I put, "as little as possible to extend bottom time." This may be incorrect.

    Great, Perrone, then they designed it correctly. :wink:
    I hear what you're saying, and I agree. Just remember, the unit is specifically
    designed for normal, recreational diving in a PADI kind of way. No deco, no overhead.

    There are a bunch of images in the RBW gallery, too, maybe you find one there.

    You got a point there, but in my experience the single most important part (assembly, actually) regarding WOB is the DSV or BOV. And theirs certainly has a different design. One-way-valves attached to the DSV, too, there can be rather big differences.

    Well, consider your location. US, with a currency currently not worth a damn. Import duties, shipping etc ... for people in Europe that Meg costs a pretty penny by the time you add around 10-15% customs duties and another 17-20% sales tax ... on the unit and all shipping and handling charges. So it's all relative.

    For this sort of recreational unit (and diver involvement!) I believe it's perfect.
    But the pros and cons of the EAC have been discussed endlessly, including my view.

    No arguments there, CCR diving does cost more money unless you spend a considerable amount of money on expensive He. On the other hand look at T1 regs, Data Mask, $2K dive computers ... plenty of expensive gear that people buy.

    And you can always watch out for the Divelife designed unit, it should come in at around half the price, with very good WOB, less entanglement points, and CO2 monitoring. Still uses EAC cartridges, though. :wink:

    I understood the Mk VI would be used with Poseidon's "The Platform", which is pretty close to a BP.


    I haven't seen the unit except at shows, but as the FL Sales Rep for Poseidon I *might* have some news before most. I will let you know as soon as I can.

    Nereus - You'll be at DEMA, I'm sure we'll get the news.

    I cringe when I hear that no offboard bailout is required. I don't think that's a good thing to advocate. Humans make enough mistakes as it is. To give someone a rebreather with very limited bailout I think is asking for trouble. We shall see though.

    about 5 training units will be in the USA before the end of the month

    I *should* get a dive or two in before DEMA

    If you are serious about one of these for you or your shop, order ASAP. I understood there are 800 deposits/preorders for the first wave already. There will be some at DEMA and additional information will be announced (please don't PM me). I suspect most folks won't see one until January if they haven't preordered one already.
