I've been popping in to follow this thread every now and again, and it amazes me that a thread about an accident that is completely explainable can carry on for 888 posts and counting.
I've been doing this diving thing for a long time, and routinely break all of the "rules" that are being cited here, as do most of the people I dive with... The only real difference is that when we are diving solo, we are appropriately equipped.
The only thing that makes this accident any different from many others, is that it involved one of our own. Which is, of course, utterly irrelevant when it comes to analyzing the events leading to Quero's death.
The simple reality is that it appears (because we don't really know the actual cause of her death at this point), that she made a few pretty basic errors in judgement, and added together, they overwhelmed her. Anyone who has read my posts on these threads has heard me say this before... It happens all the time... Complacency. A diver that is quite experienced, takes on new gear, and new tasks, and bang. There is really nothing new to be learned here.
Our local dive community lost a friend this summer when he was diving in the Florida caves. As much as his fans didn't like to hear it, he too messed up. He chose to dive using an untested tank and ended up toxing out. That thread went on forever too, and got ugly at times, but there was arguably a few good things to come out of it. Mostly though, it was a reinforcement that complacency kills. Period.
So don't pull a muscle trying to understand what happened here. Baring some new information like an underlying health issue, we need to accept that diving is potentially an extremely dangerous activity. It's easy to do, but make no mistake, the consequences of making an error or errors can be harsh. The PADIfication of our sport has put pursuing it into the reach of everyone, and that's a cool thing. At the same time, I think we sometimes forget that that every time we sink below the surface, it's possible, that we might not come back up. Admittedly, you can say the same thing about driving, taking a shower or cutting the grass. It's all a question of degree.
So before you dive next, pause and reflect and ask yourself the following:
*Are you mentally and physically prepared for the dive?
*Is your gear working properly?
*If you are diving with a new bit of gear, are you sure you know how to use it?
*Do you KNOW what gas you are breathing? Have you personally tested it?
*Are you and your buddy in agreement about what happens should you become separated?
*Do you have a dive plan and is your buddy in agreement?
*Are the conditions ok, and within YOUR capabilities to dive? Tides? Currents? Wind? Visibility etc.?
The list could go on, and on...
Diving is an amazing hobby. I'll be celebrating 40 years of doing it next spring, and after 5000+ dives, I've had a few "Come to Jesus" moments, that had "this and that" not sorted themselves out properly, I'd have been the subject of a thread here.
If nothing else, Quero's unfortunate passing will serve as a reminder to the rest of us that we are all capable of messing up and having a really, really bad day.
