| Tek-Talk: Discuss Are We Taking It Seriously Enough? in the Technical and Specialist Diving Forums forums: This was a tale of total failure to check gas on the bottom phase of a dive like we were ... |

So if it were me, I'd be looking at my gas calculations before I jumped back in the water on a serious dive. And checking just how close to the edge I was pushing it. Jason

My club are doing some nice RIB diving this Saturday. I know that I wouldn't be eligible for it because I haven't been in the water since a Red Sea trip in December and I haven't done any UK dives since the autumn. The person running the trip wouldn't be happy dropping me into even a 20m dive without some shore or quarry diving first. Si's post has shown me in rather scary detail why the club insists on this. Sometimes it's those first hand accounts and experiences that lead to guidelines like those in my club that keep other people safe.

I've had to go back and re-read that thread, 'cos I couldn't remember seeing anything particularly judgmental nor did I recall any posts congratulating Si for his cock-up. I still couldn't find this stuff. I've been criticised before now for pointing out that a poster to that forum hadn't seemed to learn anything from their near-disaster. As far as I'm concerned, if it's just a blow-by-blow account of a descent into the incident pit, without coming to any conclusions, it ought to be submitted as a 'Trip Report'. I still don't know what back gas Si was using; how much of it he started the dive with; at what time he noticed that he had 100 bar remaining and how the fuck he thought he had 40 minutes of deco to do after only 36 minutes at an average depth of 36.5m I don't know what sort of planning went into his decision to take 80% for deco when his buddy was on 50% or if they even discussed how this mismatch was going to compromise the 'plan'. My first sea dive this year is more than 3 weeks away, yet my buddy and I were discussing gases yesterday. He's DIR trained and I'm DIR 'friendly'; neither of us use 'standard' gases, but we don't just bowl up with whatever we feel like in our cylinders. Howard Payne is spot-on for bringing this subject up. The reason people are getting their knickers in a twist is the mention of GUE. If Mark Powell had made the same post, reminding us to take a bit of care about what we're doing, we'd all be standing to attention. A lot of people don't afford the level of respect they should to this sport and it's an opportune time for that to be discussed. |

the two quotes above say it all really. practice practice practice. the bit that gets peoples goats up is the inference that GUE is right. there needed to be no mention of the agency in the original post. if it works for you then its right. we all make mistakes and have misunderstandings luckily most of the time they don't cause major problems do we learn from these reports , yes some of us do , some of us don't I try to take something from each report in the I learned about diving from ... section

At no point in his thread did he say that only GUE had it right. At no point did he say that any other agency had it all wrong. All he says is that the GUE emphasis on practice and responsibility is a good thing and agency aside is something that we should all be looking at. I happen to agree, but then as a GUE trained diver I'm not expecting that to count for much. |

It seems to me that Big Si fell into the "it'll be alright on the night" trap, but that he had enough training and "muscle memory" to get out of it. My thanks go to him for reminding us of how quickly things can go wrong. I don't believe that GUE training changes anything, it merely moves the goalposts. GUE trained divers do so much skills work that they have a much bigger comfort zone than I will ever have and that ultimately there is a tendency for them to go on more difficult dives. Of course, they may well be better placed to avoid problems on the simpler dives, but these don't appear to be the focus of their diving. I have no desire to do the harder stuff because I don't enjoy it. I like simple "ooo - that's a nice fishy" diving. (Apart from ice-diving, which is simple "ooo that's a nice...errr, I don't seem to know what it is" diving I don't see any value in posting "what would have happened if I was on that dive" as whilst Howard was posting, he was warm and comfortable in front of a PC and compos mentis - not panicked on a dark, cold dive. Big Si could have easily listed what should have happened, but he posted what actually happened so that we can all see the huge difference between the 2. It is fundamentally impossible to train for incidents outside of our own comfort zone because the training ends up expanding that very zone! My personal example comes from my gliding - I used to be terrified at the thought of being too far away from the airfield to be able to see it. Last November, I went mountain soaring in NZ and quite happily flew at high speed very close to the mountains in an area 60 miles from the airfield where I couldn't have survived even if I was alive after a crash - it was very remote and cold, so I would have quite likely died waiting for a rescuer. A much better pilot than me did exactly this 10 days after I left. A standard bimble around Hampshire now appears to me to be 'danger free'. It isn't. So, my conclusion is that advanced training only helps if you avoid advanced diving. I would agree with Howard that incidents can be avoided, but only in the case where the training is way beyond the level of difficulty attempted. But we humans are not like that - we keep pushing oursleves. The 'my training would have saved me' argument doesn't hold water because the incident that hits the "better trained" diver is just more complex. Cheers, Chris PS I use the phrase "better trained" to represent what I think Howard was hinting at because I can't think of a more specific one and not because I am suggesting arrogance on the part of GUE divers.
