    Yes I wondered same thing myself and I cannot see any reason why it would need to be that way, the proper studies that have used VGE as outcome measurements haven't had to send stuff off. Is it just a symptom of the current "dickhead with a topknot" product designer obsession with making devices internet connected/reliant?
    What next an SPG that needs cloud connection to detect a bit of pipe bending and decide how far to shove the needle round?

    Or is it some back handed data gathering for reasons unknown? Going to need to pay a subscription to get your results?

    Got to say though I have no idea what is involved in data processing of ultrasound to translate that into a bubble score, maybe there are sound reasons why it can't be done on a PC locally? I'd be curious to know.

    Just personal thoughts here but this seems to be measuring the quantity of microbubbles and telling you that's good , middling or risky. But what does that bubble count actually equate to as a decompression risk?

    Does the same bubble count in an overweight 60 year old with a PFO present the same risk of DCS as it would in a super fit 21 year old? I suspect age is probably more of a risk factor than how many bubbles are detectable. Does the analysis take into account age, BMI, PFO, etc when giving results of risk?

    Anything like this I always think data is the real profit margin. Maybe I'm wrong or just cynical but I can't help wondering why they want the database of results. Might be so they can tune the analysis better. Might just be altruistic. You never know, there is always a first time in business Or it might be something else.

    Sadly, most of these new companies eventually fail. That's just the nature of manufacturing and product development. Reminds me of Liquivision. We'll alnways be there for support and servicing, don't worry, buy with confidence. If it was a couple of hundred quid, the processing was done on my laptop and the unit was designed to be reasonably easily serviced and maintained I might take a punt. At pushing a grand with taxes and no guarantee of future support or access to the server remaining free, not for me. But then I don't think it's pitched at tight, cynical bastards like me anyway

    Untrained technicians (the diver) collecting data in an uncontrolled and inconsistent way with a huge amount of variables that are uncontrolled and unquantified - the data will be useless. Its just a gimmick that someone is exploiting the average diver with

    Seems mad that it doesn't need ascent rate data, especially given that most people don't ascend anywhere near the model rates.

    Interesting device, wonder when it will get compared publicly with other methods of measurement.

    (also getting my popcorn out ready for inevitable rossh based shitfight which seems about as likely as pdf's and bullshit on a ccr thread)
    I think that ascent rate is as important as stop times/levels in preventing DCS once you get to decent levels of deco. Doesn't really matter if you carry out your stops 100% as per predive plan if you take twice as long (or half as long) as the plan to get to the stop depth as your levels of on/off gassing will be so far out that they bear no relation to the plan. Of course if using a dive computer it will immediately recalculate to take account of this.

    I would think that the most relevant metric would be a comparison between predive bubble levels/sizes and post dive as it seems that, from various studies, some people are "bubblers" and others are not so to only look at post dive without a yardstick to measure from seems a bad idea.
