When has this _ever_ happened? Is it unsafe to do a cave dive without a jack to lift up the cave if it collapses on you? If you have a failure like this at max penetration you either have been grossly negligent in your maintenance or you got caught stealing from the collection plate and the man upstairs has it out for you.
Who cares if it has or hasn't happened? The fact that it can happen and there's something you can do about it makes you grossly negligent if you don't.
 
This thread went form here to there and back.
Doubles at cavern/intro heck yes! Do it and get good with it. Since when is doubles diving resigned to the exclusive party of apprentice/full cave divers? As a matter of fact I just looked it up in my cave workbook: 1/6th on doubles, dual outlet tank or manifold.......

Just because it is not a requirement at the cavern/intro levels does not mean it is prohibited (nor should it be) or that using doubles at that level makes it unsafe.

What, now diving singles make a diver 'less of a diver' and thus they swim doubles to not be different, not to stand out and be identified as an intro diver? I find that mindset very childish and should that actually play on one's mind, they need to mentally mature a bit and then take some dive lessons.

IMHO Singles have no place past the daylight zone! It's really that simple! Redundancy = survival. I don't plan on getting in a car crash, but I still wear my seat belt!

I hope the owner of this image and set of doubles doesn't mind me posting this...:wink:
Another 24ish hours and this set of doubles would have been in a cave. This blew the day before a cave trip. :11: These aren't my tanks but I assure you that they have been well maintained.
Sometimes things happen. Maybe in Utopia o-rings would never blow on perfectly maintained gear, but in the real world they do.
 
I heard a good story about RTodd in rock horror in the restriction when his burst disk went and vented his tanks so fast that him and his buddy wound up sitting there in a temporary air pocket in the mud...

This is a fantastic strawman you have set up right there.

Hey a quick physics lesson for you, as tanks go into the water and get breathed the outside pressure increases and the inside pressure decreases. If anything is going to blow it is going to blow at the surface.

And if you're dumb enough to screw a regulator into that post that's two inches away and dive on, you deserve what you get. The mechanism to produce that doesn't exist in the back end of a cave. The truth is that you can't account for every single thing that could kill you inside a cave, and using events that have no statistical threat is pathetic.

Do you think we are making this stuff up???? :11:

I am quite sure that it is conceivable someone could shear their burst disk off bouncing through rocky horror but I do not see how it is relevant to a discussion on single tanks and intro divers who are not allowed in restrictions in the first place.
