The Isolation Manifold, lessons not learned and a small defence of the IUCRR

[Gone for diving]

If it is a bot I think it's kind of amazing that it took almost ~ 2 weeks for people to realize? Even though all the posts have been "off" I can't imagine what they'll be like in 3-5 years. That's some scary stuff!

I read that article about the bot on reddit. That's amazingly scary.

First time I thought it was a newbie that didn't know the lingo and or couldn't phrase things correctly because of being new... or English wasn't its first language
but then it was on rebreather topics
Sounding abit smart.... but off.

But that could also be me...
Abit smart, but off

On this sombre occasion it would seem that artificial intelligence has proven to be superior in comparison to the scrambled plan of action submitted by the gregarious few in previous exchanges, which by unspecified means has brought due diligence to the fact that the Do-it-Right mantra is neither concept nor copyright, but an ingratiating slogan worshiped by a select group of nobodies. Commercial divers, abalone, lobster divers (using the hooker system), combat divers, police and emergency response divers, expedition divers, marine scientists, recreational and technical divers adhere to standards set by their nominated predecessors.

Can you answer these problems?

There are no indications that ASD is real, nor if real that he has any scuba training or experience. He claims to have done OW, and his profile says he has been certified less than a year, but his posts suggest he did not learn the basics.
His first post was Feb 26, having joined SB Feb 25. He made 26 posts that first day, offering input on hoses, ears, sidemount, computers, lights, drysuit undergarmets, weights, seasickness, photography, Egypt, sharks, fins, CESA, Rescue course, IP gauge and tools, tech shorts, entry to Thailand, regulators for twins, amd SSI vx PADI for Nitrox.
The first thread he started was March 4 in Basic Scuba with a title, "Where does complacency begin and end?" with a disconnected lead-in post: "What changes have you made since you were certified?" that got 38 mostly confused responses, and to which he only offered his OP.
In one post he mentioned "Aspro," which is (I think) uniquely Australian.
In his early posts he seemed a bit defensive, looking for recognition, but got mostly ignored or disagreed with.
On March 11 he tried to get a lot of info on diving caves in Florida, but got thoroughly rebuffed.

I just consider him a very advanced 10 year old who has a dad that talks way to much about scuba. That explains a lot.

All the way open.

Valves are either open or closed. Anything else leads to ambiguity, and ambiguity + stress + limited time isn’t a great combo.

I have to conclude that you are suggesting people need the stop of a valve being fully open or fully closed to help remind them which way to turn a valve.

I can’t speak for others but there are some of us that it doesn’t matter what orientation a thread is in, we are gonna turn it the right way. I cut threads and install fasteners everyday, I’ve installed screws upside down blind and backwards.

I guess what I’m saying is if CW vs CCW rotation is confusing you really ought to practice more; a half open / closed isolator is not ambiguous.

and yet there are very experienced divers who have reported that the first time something went bang for real, the ****** it up.
Practice is great everyone should practice more under the most realistic scenarios they can create for themselves, but building defenses in depth to human error is important.

Turning a valve behind one's head is not all that intuitive. When my wife and I were first learning to dive doubles and do valve drills she struggled with it. In one instance, she checked her isolator before our dive, just as we made a habit of doing, and found it was closed. Well, of course it was actually open, and she closed it before we dived. Fortunately, our dive was a practice dive on a shallow platform in a lake. It was a great lesson for both of us. After that experience, I got ahold of a "practice valve"--a cheap plastic water valve--and helped her learn which way to turn the valve no matter what orientation I held it in behind her head. That experience made me realize that even with practice, it may never become completely intuitive for everyone, and mistakes can be made.

I understand what you're saying, but I also understand what @lostsheep is saying. I'm in the same boat. I thread pipe and put together fittings for a living and could do so in my sleep. I think when it comes to the CW vs CCW I have a little bit of a leg up compared to the lawyer who's in court all day or the banker at his desk.

It's not known what someone's background is and therefore it can't be a "one size fits all". Just because some need more practice doesn't mean it's "bad". Personally, I couldn't fathom turning a valve the wrong way, but I still practice it every single dive.

We here how memory muscle is so important in every other aspect of diving...
it think it should apply to turning valves as well.
You can always use the house faucet to practice... when the water is run on your neck,, it's on.

We could try changing the isolator to a 1/4 turn valve... but some how I think that will cause more problems...
Like which way to turn it
