    I think @tbone1004 has the answer that a lot of people will trend towards in the future with regard to traveling and rebreathers. With a backplate and wing, STA, and the Choptima, you can travel with everything in a pillow case and have a fully capable unit. Not to mention the price point is at a significant advantage over all the other choices.

    I am repeating what a non rebreather diver told me had been told to him by the instructor. I am not a rEvo diver so I don't know but for whatever reason he was asked not to go inverted on the rEvo.

    there is zero flood tolerance in the Revo. If there is water in the loop and you go inverted, that water is a straight shot to your mouth.

    Also, it doesn’t breathe well at perfect trim, it breathes NONE inverted, lol

    lots of tanks available during travel for Optima. I dove my first trip in BOnaire with the standard Optima in just shorts and a T-shirt. The trim pillow is awesome

    the second trip to Bonaire was in a CM, also using shorts and a T-shirt. No trim issues.

    Other than using sensor fusion http://www.deeplife.co.uk/or_files/Test_Data_for_Sensor_Fusion_Algorithms_RV_130325.pdf, it’s the only eCCR methodology out there that automatically mitigates the inherent risks of voting logic by design. Current limited and water blocked cells etc etc.
    Link to the original White Paper https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwj7i825ybLrAhXTJDQIHe5kDWgQFjAAegQIAxAB&url=https://zenodo.org/record/17661/files/MK6_White_Paper_v2.pdf&usg=AOvVaw1A-0txGEQM1RGZ2wHojgwB

    Any idea what it’s tested WOB in OC and CC modes is?

    Unfortunately it would appear about the time they joined RESA that Poseidon stopped publishing their very good fatality accident analysis… I’m sure there is no correlation!

    However there have been quite a few more than 3 known Poseidon CCR fatalities. I just counted ~10, that have been identified, at least one of which had the SSS. See Deep Life Design Team: databases and analysis of rebreather accident data
    2 of the more recent ones are currently or were being investigated by UK HSE.
    I expect in a few years accident analysis will be released by the US scientific diving community about their recent accident and that should be quite detailed based on precedent.

    The 'water' is just condensation, collecting in the inhale lung, you can swallow it, or breath it out by pushing it through to the exhale lung. Then go inverted and push it out of the exhale lung and through the OPV by doing an inverted dil flush .... try it if you like drills. :)

    We all know that your accident database is unfortunately too biased...
    But I admire your dedication to spread the gospel of your company:(

    even Revo’s flood, lol

    my very first caustic was from a Revo (my fault). My very second caustic was from a Revo (not my fault)

    I will append a common sense warning to the my message above "Don't swallow or breathe water from rEvo inhale lung if caustic"
