As far as the bail out capability, from what I was told by Poseidon at Beneath the Sea, you would switch to OC (a built in X-Stream Reg) and breath off your dilutent to the surface. I don't know if this changed or not. At least that was my understanding.

Correct, George. And from I was told in January the dive computer will switch to OC
when the lever on the bailout valve is moved into that position.

The Discovery is meant for recreational dive profiles, no overhead environ, no deco.
The HUD in the BOV is very simple, pretty much a dive/bailout signal.
Easy to set up, self-calibrating, easy to use. Recreational, not technical.

The BCD I saw, as well as the diver in the pics, has some D-rings, so taking along
a small 2 or 3 liter tank (13/19 cf) should not be a problem for those who feel more
comfortable with an RBS. With a buddy you'll need it anyway, IMHO, beats sharing the loop.
 
While I personally will take a wait and see attitude to the technology, for Poseidon this a big gamble. If it works, then this may be the 1st step in being able to teach OW classes on rebreathers from the start. RB divers have been saying for years (and I agree with them) that rebreathers are the next step up for diving, and this may be the 1st step to them becoming mainstream. Let's see what happens.

Very high stakes, George, very high stakes. Not just for Poseidon and Bill Stone, but for the rebreather market in general. There are still many places where rebreathers are shunned, and some where their use is restricted. If targeting recreational divers, and training them like that, goes wrong, it could be disastrous for us.

On the other hand if the electronics work it would be a huge step in the direction of safer rebreathers. So this is one of two new units that will be very interesting to watch.
 
Very, very interesting.

Valves on top unprotected. Are those single velco straps the only thing holding the tanks on? Or is there some positive lock system that we just can't see?

The hose bore looks a bit small to me (smaller than the KISS) but maybe the picture is just deceiving.

Valves look proprietary. I wonder if you can just use common ones. That hose routing looks a bit interesting too...

What are the expected costs of this rig? As well as scrubber type/time?
 
I certainly would never underestimate those involved in the development of this rebreather. However, from my discussion at the booth at DEMA, I thought that the recreational version of this rebreather was supposed to be only its first incarnation, and that, in the future, there would be modules available to the basic system that would make it suitable for technical diving.

Assuming this to be the case, the placement of the handwheels on the top of the unit would have to be changed in the future. Otherwise, this would likely become a hazard in caves and wrecks.

What's the second one?
The Open Revolution Apocalypse™ Type IV mCCR (<- link to FAQ PDF file) that will be introduced at DEMA. A manually controlled cmf CCR with rear-mounted counter lungs.

Valves on top unprotected.
As they are on most OC tanks. No overhead, no damage from hitting it. Unprotected valves upside down can also quite easily be damaged when taking the unit off. Having the weight of the valves and 1st stages up high also helps balancing the rig UW. Plenty of people have changed the tank position on their RBs (CK, Meg etc) for those reasons, and on current pSCR units it's the stock configuration (frequently in caves at that).

Are those single velco straps the only thing holding the tanks on?
Yep, looks like single tank strap. Not so good IMHO, but it shouldn't be a problem to fit normal straps with latches.

The hose bore looks a bit small to me (smaller than the KISS) but maybe the picture is just deceiving.
As they're build in Sweden and offered in Europe the units should have CE testing done, hence WOB should be in line with other units that have passed that standard.

What are the expected costs of this rig?
Around $6500, if you registerd before the end of December 07 for a reduced price of about $5750 ... you could put in an order on their website with a $ 290 or so deposit IIRC.

As well as scrubber type/time?
Either pre-packed granular (from Molecular Products I believe) or ExtendAir cartridge from Micropore.
Duration has not been specified yet other than that the scrubber will out last the 300 liter O2 supply.

You can find an info brochure (not particularly well written IMHO) as well as a interesting "white paper" on Poseidon's website.

You can find interviews with Richard Pyle and Bill Stone (<- links to MOV files, watch them in this order) that were taped at DEMA 2007 and give a good idea about both innovations and reasoning for decisions made regarding the MK-6 Discovery.
