    And I've taken my tall can Meg to Mexico, and it fits in a Pelican case and weighs 23kg. I assume you read the second part of that paragraph where I pointed out that you're checking bags either way, so it doesn't matter. But kudos for misquoting me to make your choice look better for the OP.

    And a Pathfinder wouldn't register on my list. What's your point? OP is asking for options, not giving him any reasons to justify your choice isn't very helpful.

    Just how is a mCCR an advantage in caves with sawtoothy profiles? What am I missing here?

    . Then he went on to say it would never get wet, WTF?

    Maybe he just want to collect them..

    I adore Boris, I've never owned 1 but I would hope to someday, though I personally Would Dive it, but just to have 1 would be nice too...

    I can't wait to get my next CCR and Pray that day comes soon, getting a bit pissed off without to be honest.

    I didn't see anything that implied that the OP wanted to travel without checking bags. I would never travel anywhere where I intended to dive with my own CCR that didn't require that.

    Sorry if I wasn't helpful to you, but you sound like the kind of chap that doesn't need anyone else's help anyway, so I'll live with that.

    One thing I have found to absolutely hate about an ECCR is diving sawtooth profiles. If you are in a tight area and you are forced to ascend, then your po2 will drop and the solenoid will fire. This injects even more volume into the already expanding counterlungs and can pin you to the ceiling.

    With a MCCR or HCCR, you can just let the po2 degrade momentarily until you actually want to modify it. Many times you just waste O2 since you are going to be dropping right back to a deeper area again any way.

    There is no rule that says you must keep a rock solid po2. A close average is perfectly fine as long as you keep track of it.

    Well this got a bit wild. Not sure why it says since 05 in my profile, I've never dove CC diving.
    Why do I want a rebreather, more bottom time, less bubbles, more interaction with wildlife, etc. I'm in school for oceanography and a rebreather could be a useful tool.
    Money isn't a real issue for me, I own my own businesses and retired from the military. Everything I do now is just to enjoy life and follow my passions.

    I'll try to answer some questions.
    Silent, that is a very good point on the scrubber and that's exactly the kind of input I was looking for. It's little things that are easy to miss.
    Although I have a buddy who modified his scrubber to be packable, it's not something I would do. This guy has about 50x more experience in technical diving, modification and design than I do.

    I'm not concerned with checked baggage. Hell I came to Hawaii with 3 checked bags and a large bicycle just for vacation but transporting it all from the airport was a hassle. My travel concern is breakdown size, ease and durability. I liked the optima because I know a few guys who dive it and I watched one take a spill and tumble down a hill without any damage, except to the owners ego.

    And why can't you do that with ECCR? when I am cave diving I put my setpoint at .7 and try to fly the rig at 1.0 manually. I rarely hear the solenoid fire when I do that as I find it quite easy to fly my ECCR in manual mode.

    Because that is not what was asked. You would essentially by running it as a HCCR rather than ECCR.

    I was referring to running in full ECCR mode. I have a hybrid unit and leave SP at .4 all the time.
