Rebreather Science...

Buddy had his rebreather electronics flood on a dive at 160' and fill with sea water. Then the next day he goes to 330 feet on the same repaired box. Typical dive profile was 4 - 5 hours.
Interesting show...

No argument. I was just a little shocked they went to 330' the day after pouring two cups of sea water out of the electronics bay. This while power was applied to the unit for an hour and a half while they ascended. I would not fully trust a flashlight that flooded until I had taken it for 2-3 dives.I, too, would like to know how to perform such service on my unit. If my handsets were to flood, my only option would be to send back for service. Of course, Richard Pyle is one of the most experienced rebreather divers on the planet.

I sometimes wonder if this isn't done for a little drama to sell the networks. Stan Watermans films always had something, the guy who was bit by the seasnake, oh no, did it break the skin? We'll know after this commercial if he's still alive! His daughter swallowing a brissle worm, I think since everyone learned from him they've all adopted that format.
By all that is wet, I do hereby swear, (politely), and attest, upon pain of never diving again, (real or imagined), that I understand and affirm, that I agree to the above.

If you were going to do a dive of this magnitude for national TV, wouldn't you try to carry a spare head?

Yeah, sw in electronics destroys pretty much everything. I am sure they just fixed the housing problem and replaced all the guts.

Some day, I would like to be able to afford a spare head.

Perhaps. I actually saw it again last night and you could see bubbles coming out of his rebreather during the ascent so I doubt it was staged. Who knows...I sometimes wonder if this isn't done for a little drama to sell the networks.

I did note they were having issues with a "CIS Lunar" if that means anything to you...

some bubbles coming out of a rebreather on ascent is normal (small) due to over pressurization valves on the circuit opening so as not to over inflate the divers lungs. now a large number of bubbles is a bad problem.
SDM care to add anything?

They commented on the bubble volume over the underwater comms. Again, might be for drama.some bubbles coming out of a rebreather on ascent is normal (small) due to over pressurization valves on the circuit opening so as not to over inflate the divers lungs. now a large number of bubbles is a bad problem.
Feel free to watch it yourself and let us know:

One of the things that comes along with switching over to a rebreather is that a lot of divers have to learn how to keep from accidentally venting precious gas out of their noses and masks. It is not a big deal on open circuit systems, where you usually have enough gas that a few bubbles lost here and there don't matter much. However, in a rebreather, which typically has a very limited gas supply (such as 13 cubic foot tanks), any such leaking counts a lot more. So, divers have to make sure not to accidentally let out any of this gas from the breathing loop when not intended. It is not as easy to do as you might think.

I thought the deep divers were so funny. Typical science nerds when they found a new fish. It was a great show. Thanks for the heads up.
Then I saw that the "hosts" of the show do other "abyss" shows. There was one about the Amazon but I missed it.
