Hi Bill!
Sorry I haven't been around for a couple of days... Been slammed busy diving. Then I rebuilt the fill panel in my shop. Then had dive club. Then dove some more. I haven't really had time to follow this like I wanted to.
There's a lot to respond to that's happened here in the past couple of days, and I can't afford to spend my day on a computer... But I'll do my best to touch base about the main topics.
In summary
1 Complaceny. This is our local lake...
(snip)
2 Poor/Weak Signalling technique. Some have ...
(snip)
3 Lack of urgency. I've included...
(snip)
5 [-]That you can slow down the rate of air loss by kinking the hose. Noted and learnt[/-].
Yes, you can... And no, it's not magic or some sort of "Boy Comic" stuff or "beyond the realm of super-duper technical cave commercial recreational sport deep decompression rescue" diving that has something to do with "modern" vs. "antique" scuba gear either. I'd have done the same with a garden hose that exploded if I was trying to save the water.
I wasn't suggesting it as a solution to the problem of freeflow... I just said that it could be done and yes, it would slow or stop the freeflow while a diver figured out a resolve to the problem. I mentioned it because that's what I would have done while addressing the issue and/or getting to the surface. I also mentioned that I would have fixed the second stage underwater first, but kinked the hose and ascended if that didn't work.
That said, while I disagree with the idea that you should just "forget about" the ability to kink a hose, I've already said that it's not a real solution and therefore not on any agency's training list, as far as I know. It offers no permanent solution, but it might save you some gas, reduce the urgency of the situation, and prevent water entry into the first stage.
Enough said about that... I don't want to bother to argue a point that's not in any agency's official training. You did right - finding out that it can be done and taking note of it. Done with the subject.

Here's what I see you doing, Bill... Just a casual observation:
I see that you had a lot of issues on this dive, and have posted a video for all to critique, in the interest of hearing people's opinions and suggestions. When they point out the issues and suggest solutions, you justify your actions and practices and essentially ignore the solutions that are given to you. Perhaps the word "ignore" is too harsh... Perhaps you hear them, consider them, and then find reasons to not use them and instead choose to continue to do things as you've always done.
Guess what? No change = no change, regardless of what country you're in.
We all dive in water that is cold sometimes, and we all dive in water with less than perfect visibility. Yesterday I was diving in true blackwater conditions... I literally could not read my guages if I pressed them up against my mask. The current ran about 5 knots one way, slacked for about 20 minutes, and ran about 5 knots the other way. Our tidal differences were about 11' yesterday. (3 1/2 meters to you Redcoats
).
I didn't hold onto the line as I descended. Sure, I used a cave line as a guideline, but I didn't descend on it. Had the vis been as good as in your video and there'd been no current, I'd have been watching it while descending and ascending, but not touching it - that way I could see my buddy and him see me so we could be aware of what each other was doing. If you and your buddy had done this, things would have gone a lot differently for both of you in a variety of ways.
You can justify your actions all you want, and you can sit here and tell us all that your buddy is the greatest buddy in the world and you can claim that the UK only passes the best regulators and the fact that they meet "minimum performance criteria" is really important and that there was nothing wrong with your regs... But if you look at the video, you can plainly see that yes, there was something wrong with both of your and your buddy's regs. You being in denial about it does not make it true.
Here's how to solve a few major issues (I don't have the time to get into everything today): Get a set of regs that work. These don't. I don't care how you do that - fix the ones that you've got, buy new ones - whatever. If you were to ask me (and you did), then I would tell you that a great set of new, round-faced, downstream-style regulators - and either identical or nearly identical to your buddy's - would be my choice. If you're going to sit and justify and tell us all that there was nothing wrong with your regs, then I can't make any suggestions that are going to help you.
Ditto with your buddy... He may be the greatest guy in the world, but he had no idea that you were having a freeflow, had zero situational awareness, and actually cost you several minutes in getting back to the surface. I wouldn't call that a "great dive buddy" as you have said. It is what it is... Stick with him or don't... Or both of y'all get some training and learn how to BE "great dive buddies." But don't sit here and blow smoke and tell us that he is when we can plainly see that he is not. Denial doesn't look good on you.
Your skill set is lacking. This is not your fault, so please don't get defensive or deny it. "It is what it is," and already you know there's something wrong, else you wouldn't be here soliciting opinions. Quit being in denial about it so that you can move on and fix it. Clearly you are going to need to seek training OTHER than what you've already had - and I would suggest it with an agency world-reknowned for quality of training. Your diving doesn't affect me - that is, I don't care what agency you pick or whether or not you choose to do it. It simply doesn't matter to me - you're not my dive buddy. But you did ask, so it's only logical that if you ask me, I'm going to tell you who I think would best solve your issues that I see in this video... GUE. Take the advice or leave it - it doesn't matter to me. However, if you don't get some different training, then you're bound to continue to have the same issues, and that's all there is to it. A solution requires change - take it or leave it. Change or don't. I don't have any reason to say that, other than "you asked."
I'm not trying to be a jerk about this... In fact, am actually trying to be very nice about it. I won't be offended if you or someone else has another opinion. But to me, "it is what it is," and what I see is a real need for help in a lot of areas - and some regs that work.
You can discount DIR as a "style" and argue with me all day long that you like a different "style"... What "style" are you using now? Is it working for you?
*I* don't think it's working for you. I think it may be time to try a different "style." Of course, that's just my opinion, since you asked.
Safety Stop - Yes or No?
Some slightly contradictory information here but I think it is agency related, ie just the nature of our differing training levels / training agencies.[
Really? Are you kidding? Is this your idea of "style?"
There once was a pilot flying an airplane. The airplane started leaking fuel... Somehow, the lines from the gas tank to the engine ruptured, and he began to pump fuel out of the plane into the atmosphere.
He wasn't up very high... Maybe 5000 feet or so... But was immediately aware of the problem as it spewed fuel all over the place. Basically, the plane's tanks were going to be empty in about 90 seconds. He'd only been airborne for six minutes or so.
...So the pilot decided to do a few touch and go landings.
When he landed the airplane, all of the other pilots - sfter recovering from their shock at the idea of him doing optional skill building exercises in the middle of an emergency - asked him why he didn't land immediately. "Oh, it depends on the agency that you're with - and the 'style' of the flying."
Seriously?
And now you want to discuss it and ask our opinion?
Common Kit Config
Yes this an age old debate, I dived with probably 20 different divers over the past 12 months so even if I went to a standard GUE config - I wouldn't get any benefit as none of the others are GUE. Ie, the problem of not knowing each others gear / diving different configs would still exist.
Someone has to start it... If you don't want to do GUE "style," then great... Make up your own. But I will warn you that GUE's been doing it for decades, and their suggestions might be a really great place to start.
"Drill Over" Signals
The advice has been both that (I am paraphrasing here)....
- Don't use a signal for drill over
- Use a signal for drill over
Why the lack of urgency?
This has been raised a few times - and is a very valid point. This I think requires some introspection on my part. I will certainly give it some thought but I'll also explain my thought processes as the incident played out.
Is there a signal for "Get the hell outta the water NOW?"
Signal, go... The same as what a pilot should do in an emergency. We all respect people for being able to make decisions quickly and correctly... But when it's debatable (as you seem to think it is) on what the correct methodology is to deal with the fact that you're going to be out of gas in about 90 seconds, "quickly" would be an improvement. You should have either fixed the issue or bolted. The same goes for the reg issue as the communication issue as any other issue you experienced in the water that day - fix it or get out of there.
Can you see the pilot hesitating? Suddenly, there's fuel, the engine's gonna stop running in like 90 seconds... And he says, "Hey, let's get introspective about this."
Replacing the line
I'd love to, I've spoken to Ian about it often but it's not our lake.
So? It's not the pilot's sky either. So what? Go clear the crap out of there and put a descent line on that buoy and quit making excuses. Then practice ascents and descents without touching it so that you can learn to dive and not climb a rope.
I gotta go get back in the water. Listen, man... Go fix this or don't... Quit wasting your time with "introspection" or asking people's opinions who might not know what they're talking about, might not know that they don't know, or might be a 13 year-old girl who is just ROFL at the fact that she told you to get a Spare Air and you believed her. Get some regs that work and go get some training before you get hurt.
