Has anyone seen these:

No, but I'd be very careful about using it only in private.

There are some people who regard ANY bubbles detected by doppler as a sign of DCS, whether you have any other symptoms of DCS or a history that might suggest it, or not.

Can you get it to wireless link to your dive computer and tell you if you need to do a longer deco stop?

They're on the cusp of going big-time here.

I can't think that having per diver and per dive bubble data can really be worse than not having it.

love the simulation bullshit , ffs if a diver is not already doing his due diligance and is that paranoid maybe its time to get out of the water for good,

Academic review of the O Dive portable doppler monitor below, interesting comment made regarding the proporiety method of the assessment of decompression quality.

"The diver then needs to input the depth, immersion time, dive duration, and stops performed in order to allow analysis."

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)

measuring micro bubbles post dive is probably fun but surely if you dive you will always have micro bubble formation on surfacing, it's just a matter of how big those bubbles are and how many? so what you are measuring is the quantity of detectable bubbles not decompression risk unless you equate the two.

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?

It sounds like a machine that tells you what your blood type is after you chopped your finger off. At least you know for the next time.

I'm guessing it's aimed at the people that will spend two grand on a torch.

After a quick read, it seems the analysis is done server side? Seems a hell of a lot of money to spend on something that might well end up useless if the company goes bust (which is very likely when you look at the history of "revolutionary" dive kit) and you can't do the analysis on your own device.
