That's not particularly relevant, the strength of an argument does not rest of an appeal to authority, but rather on it's quality.
Yes, if I were needing to cave dive I would not be looking for a cave class, I'd be doing a lot of reading and looking for a good series of check-rides, just as a champion pylon racer who'd been flying a Bearcat would not be looking to retake his private license to transition to a Sea Fury. But you don't seem to recognize that there are other competent pilots out there, most of whom are your equal and some of whom are your better.
No, how it happened is obvious to even the least experienced observer, an instructor who was unfamiliar with the training location took two students out anyway and almost killed them as a result.
Did I say otherwise, or is it just that you like to fight? My only point is that a competent instructor could (not should, could) conduct an intro class with his or her students using a single tank with two regs. That's all.
Wow, "Nickel rocketry" and "short cuts," modern replacements for "farm animal stupid," ad-hockery" and "stroke"? Some things never seem to change.
Let's face it, cave diving with anything but the best, most reliable and most dependable gear (often the most expensive) can always be categorized as "Nickel rocketry" and "short cuts," do you happen to own a custom, low cross-section, graphite fiber, hard suit? No? Why what kind of "Nickel rocketry" and "short cuts" are you engaged in? You see, we all know what we all are, we're just arguing about the price.
If you know what is best why are you having such a hard time making your case that you have to drag in strawmen that were never proposed and accidents that have nothing to do with your point? Make your case ... go ahead, we're all still waiting for it.
I've got nothing else to do tonight except this. Let's play.
Before we go any farther, what words are allowed? If not nickel rocketry, how about cheap? Does that sound better? Instead of cutting corners, what would you like me to say? Please, so we can be sure to use the right terminology.
Thre JB incident is a prime time example of why you need MORE gas on a cave dive. The student's didn't know any better, and the instructor goofed (badly). If they had half the volume (single tank) they probably wouldn't have survived. Cave dives get screwy sometimes. Having more time to solve problems is one of the major benefits of a large reserve.
What exactly is the advantage of a single tank? We've long ago listed the numerous shortcomings when compared to a dual-tank system. So if there is no advantage and only disadvantages, whats the deal. They're either too expensive (nickel rocketry...errr... cheapness) or the diver doesn't want to invest time into using them (corner cutting, or your term of choice).
Lel to the hardsuit. So we're going to walk on the bottom now? Cute, but telling of what you know about cave diving. I could buy any regs I want, any suit I want, and tanks I want, etc. I buy the good stuff that's been proven through years of use. Anyone can do that without spending a million dollars. But foregoing
critical gear because of stinginess is ill-advised. You've got to pay to play, and if you can't, don't. Just wait a little till you can afford it.
The accidents and incidents in cave diving often show us a lot. A class would fill you in on some of that. But you don't need one, right? Nothing to learn here. There are plenty of divers that are better than me, plenty that are equal, and I'm sure there are a few that are worse. I still respect learning, and a lot of divers who are equal, better, or worse than me respect the same thing and get proper training.
Good thing you aren't interested in cave diving. And for that, we thank you.
