You're talking absolute rubbish, and I suspect you know it. The industry is pretty well agreed on appropriate and usable rules for what redundant gear should be carried. Not 100%, but certainly 90%. Sure, there is no such thing as perfect redundancy and despite your preparations you may come unstuck, but that's no justification for ignoring the recommendations completely.
Maybe you'd like to list the rules your talking about and name your source.
Some solo diver use vintage equipment...double hose reg, no bc, no redundant breathing source and so on.
TDI allows just about any redundant breathing source in their solo course, including doubles...only many don't concider manifolded doubles as solo diving equipment...to that would be added a "buddy bottle" or the "doubles" would be independant.
It all kind of depends on the nature of the dive and the environment.
Notice how comon it is for a DM to jump in solo with nothing but a single tank to hook a wreck? Isn't that "the industry"?
Not so. I am obliged by law to try to find/help/save/recover you if you were diving with my operation. And I can be held criminally liable if the authorities believe I was in any way responsible for or compliant with what happened to you. That's true here in Belize, I know it's true in Britain, and I'm sure it's true in the US. It's true in the Egyptian Red Sea. And in the Maldives. And in Australia. In fact, I think it's true in every country I've ever dived in.
It's very simple - if I know of your attitude before I take you out you'll be looking for another operator. And since I'll feel duty bound to warn others you may have a long search. And your first dive with me when you behave seriously irresponsibly will be your last.
You make it sound like everyone dives with an "operator".
We live in a society in which we look out for each other.
No. We live in a society where nobody wants to be responsible for anything and people a becoming satisfied with living in nanny states that make all their decisions for them.
Society norm provides that the emergency services WILL look for you and try to save you, and that is enshrined in law and practice in most civilised countries. I'm not familiar with detail of law in the US, but in Britain if by your reckless behaviour you do endanger people you should reasonably have expected would try to save you you can be held responsible to them.
Well, I read someplace that someone in Britan was trying to introduce legislation to outlaw knives...and they've already done away with plenty of things that many of us wouldn't want taken away here. I don't think that I want to use Britan as a model.
Suppose by your own reckless driving you're in a car crash - do you think that EMS will try to get you out? If they're hurt is that their responsibility or yours? What if your house catches fire?
Lets not suppose anything about driving because we're not talking about driving. We're talking about diving and if I dive alone, it's pretty hard to get anyone else hurt without them making some poor decisions of their own.
The expression "no man is an island" is absolutely true these days.
If you jump into a great big ocean you might be lost. It's pretty much a given that someone will be. If one finds that unacceptable, then maybe they would be better off not diving. Either way, I don't want them sticking their nose into when, where and how I dive.
