    Maybe if the gear has been sitting on a shelf in the garage, not serviced and is being used for the first time in over a decade.

    Depends...if one pushes their dive to the point that they are low on air before they start ascending a casualty that would normally be of minor to moderate concern can quickly become a crisis.

    Reading the the description on youtube, written by the person who shot the video and had the problem, implies that they had air in the tank but the regulator malfunction cut the supply off. There is not enough detail posted to know exactly what happened. Here is what the person wrote about their incident:

    "This video is about Scuba Diving the shipwreck A.E. Vickery. I had a dive accident on this dive. The accident is in the very last couple minutes of this video. It is uploaded in it's entirity [sic] on another video on my channel, however it is shortened on this one to conserve time. The line on my SPG came off, and a malfuntion [sic] also occured [sic] on my Aqualung Legend LX regulator at about the same time too. No air. Otherwise cool dive. Awesome ship wreck. The current is really strong and not to be underestimated."

    "the line on my SPG . . ."

    What is that?

    I've had bubbling from my SPG too but had it fixed before next dives. Never was so many bubbles and even during the dive, twisting it, slowed the leakage.

    In the case of my SPG, iirc, it was an oring or some such, nothing about a "line".

    I'm still curious as to why no one in his three some had a safe second.

    Might not have looked like quite as much a cf if they hadn't needed to stay on the line.

    Was still a CF though.. The air-2 wasn't long enough to donate. The air-2 started free-flowing. He was left at some stages with no-one donating. The second diver "lost" their octo and never attempted to locate it while buddy breathing...

    It would be stressful to go OOA on a line in that kind of current but I can't help but think that it would have been so much easier to deal with if they'd had a long hose, real octo, and better training.

    Ah, so I missed that. If I'm understanding you correctly, one diver did have a safe second but lost it behind him and in the moment didn't sweep for it or did all 3 have air2? This explains to me why the ooa diver seemed to have not been buddy breathing towards the surface. By that point, he appeared to have constant access to a second, whereas earlier in the clip . . .well that's when things were pretty pear shaped.

    Clearly in hindsight (for the divers) they were unprepared for this kind of event, and had poor equipment configurations for this environment. Possibly a case of adoption a config based upon something they've read or that their peers us with little thought as to how it would work in practice.

    It wasn't a particular onerous current. When the first air share failed, and the second person took over, the first should have held back. In the event they had a 3 way CF.

    They failed with the primary IA (Immediate action) Give the victim air (that was done) but then control the diver firstly and think about your next actions. They were clearly task loaded.

    The better thing to do in this case (IMO) would once the diver had air and was settled, to separate from the line and make a free water ascent. they had dsmbs. Hanging onto the line meant that they had no room to maneuver. The OOA diver was the one controlling/hindering the position and subsequent ascent.

    I maintain that a (conventional) long hose would have been a hindrance in this circumstance, a 40" with a swivel would have been a much better option. I'm also a huge fan of the "English" config where the Alt 2nd (Octo) comes from teh left and is on a swivel as its much easier and more natural to donate.

    The guy with the pony was a clown for complicating things and not retrieving his octo. Basic stuff.

    A prime example of people never practicing their basic skills once learnt.

    Learning: practice air sharing so you do not give your panicked buddy free-flowing regulator

    Learning: if you have console SPG / hose protectors, it's much harder or plain impossible to check hose condition to avoid similar events

    Learning: divers should be taught about the severity of the HP hose failure so it does not immediately lead to panic

    Possible learning: always have enough gas reserve so HP hose failure is not an emergency but just an inconvenience

    You can't do that there. It is a major traffic channel.

    Very likely.
