The existence of this thread is the indication that the industry has legitimate safety problem.
Most of the divers who have died at this site over the years has been due to inexperience and really basic mistakes. There seems to be one about every 4 years or so. You might view that as...
That's because some of us think AOWs are a bit of a joke and the whole series of courses should be in the OW course, like it used to be.
And I'm basing that on the inexperienced divers that I've taken out at cove 2 with less than ~50 dives or so, and I don't think anyone should be doing that...
If that's a snap from the dive operation the next day and roughly where she was found then that is maybe 200 feet from the honeybear and pretty straight out from where the ladder truck was. It is also right along the typical route that divers travel to get to the honeybear using the rope trail...
I've tried and stuck my head in there as far as I could go. Very hard to get into any significant trouble with the honey bear that any old piece of junk underwater couldn't cause.
Pretty sure I've done single stage dives coming from Grand up the PDL line which have been over 120 minutes without violating thirds at all. I thought the average depth of the cave there was no deeper than 25 ft or so, which gives me a total runtime of 151 minutes on 2 Al80s consumed with a...
The valve is just a normal valve on a scuba bottle. You could route off board O2 into your MAV or you could come up with some kind of additional in-line valve to shut down the leaky valve. But now you've just added more complexity (and you're even more likely to dive with the MAV on and the...
It isn't though.
You have to turn your O2 off or the valve leaks constantly above water the whole time you are gearing up (and if your valve knob gets bumped in the back of the truck and rolls on a crack it'll drain your whole tank). That means you typically shut down your O2 after you've done...
And is there any actual evidence in this thread (sorry there's 30 pages of it now that I haven't read and I think I ox-toxed trying to read half of it) that points to hypoxic bailout or the DSV/counterlungs killing him due to flooding?
It still sounds like this was a third dive to retrieve the...
This is taking the wrong lesson from team diving. If you have team separation now compiled with a rebreather problem, then you have insufficient bailout and you're dead.
Reminds me of Program Managers who learn about Agile methodology and what they start doing is hour long morning standup...
A diver who is close to neutral on the surface is going to be heavily negative on the bottom as everything compresses. Try sinking to 220 feet without adding any gas to your drysuit.
Anecdotally none of the bodies we've lost around here have floated to the surface that we're aware of. Ones...
Gas embolism due to DCS could easily cause unconsciousness at the surface -- and the diver would likely have a minute or two when they felt okay before they were disabled.
Also if his BOV/DSV wasn't closed when he went unconscious his loop could have flooded and made him negative and pulled him...
I can come up with a simple way to general simultaneous failures provided they were both following the same protocols. Since it was the third and last dive of the day it makes it more likely that they were low on scrubber and/or onboard O2 and dil. Also if it was a bounce dive "just to remove...
If both divers had run out of higher percentage O2 (possibly due to bailing out) and were on hypoxic diluent (either with or without a functioning RB) then there could have been a situation where both of them would have had to try to do a blow-and-go from 20 feet to the surface with hypoxic gas...
That is another assumption.
All it takes to be filmed whist filming on a CCR is being CCR trained plus having another video camera to use. If you're aggressive enough then you can take that video literally the day after you're first CCR certified (not really wise to do that because your...
CO would kill both of them on the bottom. As they descend they have to add dil (which is presumably where the CO comes from) and the ambient pressure would increase their pCO just like it increases ppO2 and the highest concentration and largest effects would be on the bottom, also once they're...
I've had CO2 issues due to overexertion on OC. Chasing after a buddy with long legs and big fins in a cave class. We dropped down to 70-ish feet at one point so I got a bit of a narc on, and the instructors watched my perceptual awareness narrow and then threw some **** at us and we completely...
Speaking from experience with our local dive site which sees the bulk of the fatalities, generally dead divers wind up on the bottom, not on the surface (although one of the two events I was involved in the diver was on the surface, but she was conscious on the surface for a minute or two before...
