Cardboard, an easily recycled plastic lid and a plastic bag. All fit nicely into domestic recycling containers, unlike a keg for granules.

A keg can still be recycled -- or used for other handy purposes.
There were other poor comparisons in this thread, but whatever....

Hmmm. The container that holds my sofnolime (that I bought from you, by the way) is recyclable here...

Must be more than a couple of months...the 2 kegs I got from you were ordered nearly a year ago.

Hmmm just got a new batch of Sofnolime 20Kg containers... and these newest ones don't have the recycle markings.... so apparently it's not consistent and must vary depending on Molecular's vendor of the moment for containers.

Keg fits in my recycle container easy.

I don't care which you use. I don't like the cartridge cause it limits you. I can ship both but a Keg will get me more dives per size then the same size of cartridges. And usually, they have sorb, and not cartridges. But, sometimes they don't have either. But, I haven't been anywhere yet where they had cartridges and not sorb. LOL

And they make a great shot-line bouy......

I too am unclear why you feel the O2ptima not an expedition rig.... that was originally a stated goal for Dive Rite: an expedition rig that could also dive recreationally.

I've also pondered as too what make a rig a expedition Rebreather as well. Too me it really comes down to two things for myself to consider a RB too be a expedition RB. First is endurance of the rig, the manufacturers/tested endurance not, well I know I can dive 6 hours because it warm water stuff. Secondly the robustness/configuration of the RB. Here's how I see the pecking order/classification.

1. Oroboris/MK 15.5/15/16 a purely expedition Rebreather just for the size, duration, and back mounted C/L.
2. Meg/Prism Exp/tech/rec basically a Rebreather for most styles of diving and a master of none. I think the rEvo once a setpoint controller is established for it.
3. Inspo/ , KISS classic, and Optima Tech/Rec. The Evolution is also in this category but I think it leans a little bit toward the rec side.
4. Sport Kiss Rec Rebreather

Here how I criteria for styles of diving.

Expedition:
Multiday, deep, long (3 hours+), very little support as far as getting the Rebreather repaired.

Tech:
Basically anything below 150' or a dive with a hard/soft ceiling.

Rec: Dive 0-150' no deco and no wreck penetration.

All this is just my opinion and I sure its going get somebodies hackles up. But its my opinion and I'm entitled to it.

Nice analysis. Have some green!

Toss the CIS Lunar onto "Tier One" with the Mark-15 and 'Boris and you pretty much made the correct sort. Think from a field-durability standpoint that even the 'Boris comes in second to the Mark-15. Mark-15 is basically repairable with hand tools and hardware store parts if it gets smashed, and there's little that can be done to a 'Boris without the correct parts. I even think that the old metal center section Mark-15 is more robust than the Mark-15.5/16, as the metal can get bent and be bent-back with a pall-peen hammer while the plastic can crack. Old "Heavy Metal" still has it's place at the top of the list.

rEvo will be interesting to watch. Chassis seems great. Think it's likely the hot-lick in a mCCR right now, and an eCCR version cannot not be far behind.

Forgot about Cis it defiantly can be added to expedition Rebreather.

Well Scott, you just described the Prism very well. It can be dived with no power, no electronics, is easily repaired in the field and has beed dived many times past 500 fsw. There is very little that can go wrong with it. I have close to 400 hrs on mine and I do all my diving in far away places, have yet to miss even one dive due to a unit malfunction. My spares kit is some o-rings, a spare 2ndry display and some epoxy, don't even need any tools other than those needed for regulator hoses.

And I guess the Prism is master of none only if one doesn't care at all about WOB, size and weight or scrubber duration. I just got back from 2 weeks in Indonesia, 53 hrs with 1 keg of 6-12 Sodasorb, 6 fills. Anybody else done the same on another unit? -Andy

IMO I don't classify the prism as a purely expedition Rebreather. In fills my criteria of Expedition/tech/rec. But tends to fall more in the middle as a technical diving RB IMO. Not rugged enough to be a purely expedition RB IMO. I'm not looking at starting RB wars all this is purely my opinion.

Sure Scott, everybody's entitled to their opinion. And I was only responding to the particulars of your post.

Is ruggedness only measured by how much abuse something can take? Or do simplicity and ease of repair count into the equation by virture of improving reliability? A fancy, integrated deco ECCR with lots of safety enhancing computer monitoring is not much good to you if it decides not to boot up on the boat deck.

I'm not to sure what the value of parsing out such classifactions as a "purely expediton" rebreather. I think most of us understand that doing a 22 hr cave push with an SK is beyond the design envelope...
