Two sad, real stories of something that made me question about human evolution...
(Interesting enough, these two anecdotes involve nitrox understanding)

Story number one: last weekend on the boat there was this guy wondering about the difference between air and nitrox. It turned out that he didn't know that air has actually "only" 21% of O2 (while nitrox higher concentration). The scary part is that this guy have been diving using a Galileo with the oxygen at 100% instead of 21%.
I don't even how was possible for him to follow his computer... I've never used a Galileo, but I'm pretty sure that if you set O2 at 100%, and you go deeper than 6 meters, the computer will scream like a moth3r****er...

Story number two: yesterday on a different boat the dive master in training (repeat it slowly, a dive master in training) said: 'If you are on nitrox, you can stay down longer because you use less air."
He actually said it twice, in two different occasions...
This dude actually beliefs that if you use nitrox, you can stay underwater longer because the air in your tank lasts longer...


These stories are funny, but they are also very dangerous...
Anyone?
 
not life threatening though
 
worst thing seen? speedo - on a guy...

Not much worse than a grossly overweight man with a hairy back wearing a banana hammock...

A friend of mine showed me his computer after he finished his AOW dives. Because it was 'acting weird.'
That would be because his last dive (keep in mind this was a training dive...) put him well into deco. Which, of course, they didn't do.
Happily, he didn't show any sign of being bent, but the potential, especially on a training dive, was concerning.
 
I was diving the Coolidge - a pretty large and deep wreck - in Vanuatu after I'd done the wrecks in Port Vila. I'd made friends with a really cool Canadian girl and lent her my gloves and computer and BC so she could dive those wrecks. Before I flew up to Santo to dive the Coolidge I asked if she wanted to join me and mentioned that she would have to rent gear and a computer if she intended doing any penetration and deco diving. She had rescue diver cert from Roatan and looked at me and asked me what deco was..huh?...decompression...what does that mean?

I also did a LOB a few months ago with someone who declared to a very alarmed table at dinner that he hadn't looked at his computer for three days because "it would not talk to me" so "now I am not talking to it" ....ummmm
 
What is it about the Coolidge?
I met a diver who said he did a 'try out' dive on a rebreather on the wreck with no training or prior RB experience other than being told 'breathe slowly and don't flood the loop... and come up if the light goes red' :eek:
 
A student during my OW course nearly panicked during 3 out of the 6 checkout dives. Nothing overly dramatic, in the end. She had experienced CO2 build-up short after descent and signaled each time to resurface. She was able to do so in a controlled fashion. However, it had proved impossible to calm her down and get her to deal with the situation at depth.

After the last course dive, her boyfriend, who's a long-standing member of the club, tech diver and a friend of the instructors, cleverly decided to make a scene when he learned that the course director had turned her down for the certification. That was totally out of character as far as this individual is concerned. It also happened in public, in front of almost all the club members at a ferry pier, while waiting for boarding. The discussion started to heat and he was confronting the course director head-on, who remarkably kept his cool and manners throughout. It was eventually defused with the intervention of more or less all of the instructors, although the conclusion was along the lines of a forced retreat by the offender.

It was fairly embarrassing, it didn't help his girlfriend cause in the slightest and it was troubling to think how even cool-headed people can completely lose their rational thinking over petty wishes.
