I met Charles a couple times and he really was a nice guy. Condolences to his family and friends.
I was going to keep my mouth shut, but I have to say a couple things. First, reading below it doesn't sound like any training standards were ever violated. I heard speculation that the instructor or shop lead this dive and that is false.
As far as "culture" of the shop, do you mean you're likely going to be asked to have lunch while talking diving or offered a soft drink when you come in, yep. There's that culture. Or do you mean you're going to argue with the instructor because he wants you to "do it right" and you want to do it a little different. That too, I'm guilty. Or how about the awesome price match policy they have? Why buy online when you can touch and see the product and they'll price match anyone else, even websites. Training? Well I can only speak from my experience of OW, AOW, EANx and Deep, but you're going to get a lot of emphasis on "buddy diving, gear maintenance, mindset, plan your dive and dive your plan and being smart." For example... "James, quit freaking spearfishing solo! You can do it safely with a buddy." That kind of culture??? Regardless, I'm pretty sure this is blame storming which is against the rules in this forum.
I have no idea if Mr. Odom failed Intro to Cave as this keeps coming up, but it stands to reason if the shop had a bad "culture" or didn't care about standards then if that's true he would have just passed him, right?
I don't know the exact details of what happened, but I'll say this. It sounds like a medical issue, possible CCR malfunction in which Charles did exactly what he was trained to do... Bail out. Everyone can speculate on whether or not this dive team should have been there, but this wasn't with the shop or instructor mentioned earlier.
Now as far as starting your dive career on a CCR. Well, Mr. Odom appeared to be doing pretty good in life, working in the financial services industry (like myself) gives you a pretty good knack to determine a good investment. And as all of you CC divers know, if you can get into one of these units it will pay for itself quickly in expensive gas savings. For most of us the initial cost of one of these units eliminates a large number of people. But, if I could afford one of these units, you bet your ass I'd start with one from OW. In fact, what a great way to really learn to dive your machine. All of the steps of your training done under the supervision of an instructor.
Also, I'll add in the case of Mr. Odom. We have no idea how much time he spent on his unit. Hell at his age and with a possible good fortune and being the boss, he could have cut out of the office every day and dived. We simply don't know. All speculation.
Finally, I could walk into any one of your shops right now and throw $15k on the counter and say, "Teach me how to dive this thing." And every one of you would start cutting the webbing to rig me up.
So what do you want to talk about that we can learn from this incident? Immersion Pulmonary Edema? I know little about the risks for this. Can anyone thoroughly elaborate?
