This could change SCUBA as we know it.

Do you have one for your regular scuba gear?

Indeed. Backup in such an unforgiving environment is an absolute must.

My question is how they're gonna get around oxygen toxicity under pressure.

I'm certainly no expert on diving but I totally agree and have never went diving (in my younger days) without backup.

It would be cool to use in the pool. Down deep requires exotic mixtures.
Too rich for my wallet.

Maybe this new fandangled mask is best suited to footling about in shallow waters?

Funny. Because when I was at school I once wrote a mild scifi story about the future undersea life of mankind - and described a breathing device that essentially only was a mouthpiece with a small electric pump that filters oxygen out of the water. Essentially the thing that they realised now, I even had a look on mind that was not too different from what I see here. The teacher was not convinced, saying that the idea that the breathing under water would not be restricted by oxygene reserves but the duration of a micro-battery was "absurd".

Hey, Mr. Teacher! We had button cells for clocks already back in the 80s!

I will sue these guys for stealing my idea.

Actually, A heli-Ox mix isnt out of the question, it'd just let you take more Helium with you.

Like AK said, I'm not a sipper either, so buddy-breathing at the bottom of a tank scares me. I've been so low on air before that my tank was less dense than the water, forcing me to hold on, upside down with a totally empty vest, to the anchor line on my deco stop.

And Yes, I too wear a dive watch, don't totally trust computers, and still manually log my hours.

Plan the Dive, Dive the Plan.

You may be able to negate their patent under prior art rules lol.

Ahhhh! So true!

Again though, oxygen is deadly at depth. Unless there is a way to add helium or other inert gas the use of this gizmo would be limited to 15' or less.
