    One thing I didn't understand from the vid was how does it keep the loop volume down overall, ( since it adds 2.5 x the volume in ccr mode to O2 used) and for it to keep po2 on ascent how sensitive is it to loop volume. Assume it use adaptive po2 set point based on the feed gas and runs near fo2 (slightly below) at shallow depths, but interested in how KG has envisaged this to work.

    It has a HP sensor and is calculating whether you have enough BO to ascend to the surface. And I will also add that the onboard BO is only up to 20m according to all the Standards of recreational rebreathers that I have heard. To go to 40m you are required to sling a bottle. Unless those standards have changed. I think it is similar to OW and AOW.

    Wow... Just seen the video for this new rebreather.

    With a low enough selling price ie 5000 US, I suspect that some dive operators may buy some of these???...

    I am astounded that they have packed all the technology in there for the price.

    I am left feeling that perhaps the option to retrofit a bottle of oxygen and side slung bailout and run this as a fully closed unit would also be a good option...perhaps this is coming - thinking about it this could be pretty appealing as a CCR unit..

    I am personally not convinced that this unit will make lots of money ... But could be used as a marketing tool for hollis. - it will certainly be visible and get lots of looks on the recreational dive boats.
