    Thanks Luke
    Hey luke

    The WOB on the Optima is very low. It's easily the same as the Meg or Inspo, very pleasent to breathe from in any position.

    Cheers

    Thanks Seb
    Do you know if there is any test numbers to do decent comparision? If they have scubber duration nembers their should be the same for WOB .

    Thanks Luke

    If they have scrubber duration numbers.

    So far all I have seen is data from the Dolphin (SCR) that was done at 1 ata
    and hence does not reflect actual diving conditions. Dive Rite Express promised testing on their Oh Tooptima info page, but so far all that was updated are price (higher) and expected delivery time (later).

    Currently Micropore rates the ExtendAir cartridge to a max depth of 6 ata/50 msw, although I'm not aware of any test data for that depth. Considering the availability of trimix software for the electronics and large onboard gas supply there is a good chance that users will take the unit past 50 msw. As CE and NAVY testing show, ambient pressure plays a major role in scrubber duration, so testing is needed and hopefully underway.
