How easy is it to hear which post is leaking with an inverted set?

If it's a real leak rather than a bubble gun scenario then I'd say the odds of locating it by sound are even.

And of course if you were diving inverted in Florida caves without gloves [or with fingerless gloves] you could feel for the bubbles, I set up a similar experiment successfully the last time you dragged that one out.

Safe diving,
Steve

If you were diving in florida caves you wouldn't be diving inverts due to the size of 104's. (Well not unless your arms were a foot longer than a normal person). I believe we dragged that one out last time as well

Is there any other diving in Florida or is the sea just sand and dumped rubbish?

Real question. It is a State with a huge coastline but we virtually never hear of diving other than right down in the Keys or cave exploration stuff on scooters which always strikes me as a bit specialist to interest the non-spelaeologically inclined. I've dealt with a company at Boca Rotan and they put me up in a nice hotel on the beach but it was smooth flat coral sand (like walking on powdered glass) as far out as I could be bothered to swim before breakfast.

There is diving at Fort Lauderdale - some wrecks and reefs. There may well be other places too. Never been and no inclination either - bu it is apparently quite good. Aparently there is sea diving in Mexico as well

Does the Oriskany count as dumped rubbish?

Boynton Beach is apparently not bad reef diving.

The cave course discussed was in France, I think, which is generally 11ish degrees. Which is glove territory for me.

So you'd "say" it was "around" even, on audible cues? OK, lets try and be a bit more definite.

On a non-inverted set the successful "leaking side diagnosis" rates are about 80% and over for simulated (bubble gun) failures, and (in my own personal experience) 100% for real failures (only been 2-3 of them though, so the number isn't too reliable...)

Has anyone tried this, with a bubble gun or for real?

Was it simulated on the course, SteveK?

Me too, however if I was solo I'd isolate then remove my glove and check.

I've only been around one serious leak from a manifold [upright] twinset and could barely see the problem myself, so given sound travel underwater and the general kerfuffle, I seriously doubt that method of diagnosis would have worked.


Plenty of people talk out of their arse but few listen from it, so obviously listening for leaks is the Achilles heel of inverts. That said given that most bubbles IME are easily diagnosed IE: free flows and considering the DIR team ethos, I wonder how much that method is relied on in the real world?

Is that part of a non GUE cave course?

Maybe I've been rebreather diving too long but when I go back to OC then I find I can hear tiny little leaks. I spent last week caving on a twinset and I heard right away a leak that I had to search for with soapy water on the surface. Caves are very good for making you aware of noise.
