I saw a card carrying commercial diver get turned down for nitrox fill at a sport diving store because he didn't have an agency nitrox card.

Technically, it is a rebreather. He had a bucket on his head while wearing a small emergency CO2 scrubber oral/nasal mask. There was a Spare Air in the top of the bucket leaking fresh air into his bucket which vented out in the form of a small bubble stream. A full Spare Air with a worn poppet...

While I was looking into this device and its claims, I thought about what it would take to really build a helmet rebreather. If you moved the counter lung to the outside of the helmet, you could place a 6 liter counter lung in the system and free up room inside the helmet for three 6 cubic foot...

Yep, just heard the same. I don't know if it's true. But a CO2 blackout was a scenario I was ready for. When they pulled the helmet off the guy, it would have given me the opportunity to look inside the helmet and see the real story. While they administered first aid, I could have photographed...

This thing could probably support life for a half hour, maybe longer, 3-4 feet underwater as long as there is no real exertion and the diver breathes shallow. The demo diver was a big guy and it was obvious from his breathing that there was a much larger volume in his lungs than there was in his...

Ok, so now I have a quandary.... not sure what to do next.... These people have posted their slick video of their resounding DEMA success on YouTube. It, of course, depicts their groundbreaking technological advance revolutionizing the dive industry to applause and adulation. There are a few...

Also, I would like to invite them to participate in this discussion. If their device is real, I could open it up on my desk and we'd know in 90 seconds what the state of their technology is. However, when the Triton Artificial Gill was called out by the dive industry, they simply replied with...

Perfect, I wouldn't want them to accuse anyone of 'doxxing' them so we can be respectful. However, my only question regarding their identity would be if they have any background in undersea technology. Have they created any other diving products?

There is nothing to crowdfund. They are taking preorders on their website. The only funding they needed was to do their DEMA show. There was no R+D, it's just a fancy bucket with a scrubber mask and a Spare Air. They will make their money big time when they start taking deposits for preorders...

LOL.... Yeah but at least those people weren't claiming their bong operated at a depth of 42 meters for an hour on a single refill.

tech_diver's Final Report on the Hydroid Aquabreather Introduction Every new advance in diving has met resistance and skepticism. Even submersible pressure gauges were first derided as dangerous single point failures that real divers didn't need. I've always told myself to keep a scientific...

I'm back home from DEMA. In regards to the Russian-made Hydroid Aquabreather, I saw the demo, collected video and photographic evidence, interviewed witnesses and talked to people involved in its creation. The research data I collected is currently being finalized into a comprehensive report...

Okay, I just watched the 12 demonstration and there is another one at 2. The guy's head did not explode so they have successfully addressed one of the primary customer concerns. But to be honest I have no idea what I just watched. The diver laid on the bottom of the pool for about 10 minutes...

Yep, we saw this thing. Of course, we weren't allowed to examine its guts. Like Johnoly reported, there are several large technical issues like the absence of a diluent gas. in a breathing mixture rated to 42 meters that are not being addressed (ignored.) There is a demonstration scheduled...

These people are really going to be at DEMA with this device? I'm going to have a few technical questions for them.

I just got the word! I'll be at this year's DEMA working the Sea Pearls booth! Come by and visit. It would be great to meet more SBers face-to-face.

The story doesn't where or when this happened?
