Me neither -- that's what happens when I delete half a sentence and try to rewrite it without paying much attention. :shakehead: Probably something like "ASL would be too complicated for cave usage".

There was a 100% chance Walter would come in this thread to talk about ASL. I seem to remember Walter (correct me if I'm wrong) saying he would never go cave diving -- too dangerous. If you have ever been cave diving you would understand why ASL wasn't adopted for numbering -- it wouldn't...

Nice -- I stand up for the unpopular guy, and I'm accused of being the guy in question. Perhaps I should have expected that from someone in London, home of Big Brother. :rolleyes: 4 years since I got certified...such a long time. Yes, I remember exactly how I felt on my fourth dive ever...

You weren't there, don't know what happened (other than what has been posted here) and you want someone arrested for pushing? Wow. "He-said she-said" is NEVER a good enough reason to arrest someone (even if it happens regularly). The underwater world is full is miscommunication -- there's...

Note that there are multiple sides to every story -- yours, theirs, and the truth is somewhere inbetween. I see this from both sides of the coin: 1: While an instructor is doing drills on a platform, don't just drop down on it. Go somewhere else -- there's an entire quarry out there, but...

This thread has absolutely nothing to do with metric vs. imperial, and I would request that you leave the bickering out of it. If I were using the bar system rather than PSI, I would probably advocate flashing pressure in units of 10s of bars. 230bar = "TWO" "THREE" 187bar = "ONE"...

DA Aquamaster is absolutely correct. Read his post again, and make sure you understand it. Miscommunication is a BIG DEAL. It might seem funny occasionally, but it quickly turns frustrating for everyone involved, especially if time is of the essence. In this thread and others, and in my...

I'll let it sit for a few minutes (5 or less), take the toothbrush to it, and all is well.

When you wet the nylon it expands -- thus if you put it on your tank while dry and then get in the water, you could lose your tank. Wet the band first so it already expands, then put it on the tank.

White vinegar works nicely for cleaning threads and getting the white gunk off, as well.

....shower head style? Don't know that I've ever heard of those. :confused:

Good point. I've only done a dive to full thirds a few times; recently we've been hitting our destination with 200-300psi before thirds (double 130s). Then again I've only done cave dives in teams of 3, or 2 teams of 2 (more like a team of 4 but we have a 'designated buddy' if that makes...

A provisional for one stupid screwup? Who was your instructor? I doubt this is a mistake that would have killed you -- unless you were completely out of gas (and if that were the case I doubt you would have hesitated). It is too bad you were stuck at Ginnie. 18 dives for your class...

Usually they hold a good deal of poo. :rofl3:

This is true -- North Carolina doesn't normally get earthquakes. Hurricanes, however...:shakehead: I was considering coming up with a restraint system but haven't done it yet.

The "correct" answer is upright -- as mentioned above you are trying to minimize any corrosion that might be present in your cylinders to the bottom of the cylinder rather than the sidewall. On the other hand if you have compressor oil or any other moisture in your cylinder, something is...

Wow, talk about bloated pricing... Last time I had cylinders hydro'd it was $9.50/cylinder and I paid another $4 for the vis (the vis is actually $3 but they tack on another $1 for the new o-ring ;)).

Glad to see I could be of service. ;)

3500 psi cylinders are 7/8" threading, as far as I know.

What a complete waste of money.
