An age-old question: ways to 60m.

Please explain the workload reduction procedures for dealing with emergencies: burst disk failure, hose ruptures, and other equipment failures. Dive buddy emergency like loss of consciousness or oxto convulsions.

The basic rule is you don't stay so deep and you start to go up. You don't rush to the surface obviously but you don't stay so deep trying to solve problems and then go up. This is part of the training we have. If in 2 mn you are already 20 m higher you already have less problems. That means of course you don't go far into wrecks at 60 m as you will not be able to start you way up in a quick way. It is just commun sense. The dives we make at those depth are not the same as the one we would do with a CCR that's why all your comments are not bad but just out of phase with reality

I am pretty comfortable to about 190 in conditions I am acclimated to, but a somewhat recent deep dive was a real eye opener. I have never had an issue (even well past 200 ft) where I felt like I was completely losing track of time, or the situation or remembering what was going on during the dive. However, on my last deep dive (with a buddy) we made a free descent very rapidly to 195 or so, and found an adverse current (going the wrong way) and the visibility was limited at 30 feet and pretty dark.

We had to swim/crawl on the sand (busting ass) into the current for maybe 600-700 feet to reach the desired wreck. Time and air was limited, so we swam hard, and I felt that I was working at very close to the absolute limit of my physical (aerobic) capacity (for this depth). I was able to control my respiration, but it was a real chore to force myself to take very deep inhalations and exhale almost fully - which is required to work hard and survive at 190.

My buddy and I made it to the desired wreck (about 6 minutes later than we hoped). I knew the wreck well but still ended up making a significant (and stupid) navigational error by going the wrong way on the wreck. I did not realize until I got up top on the deck around 160 (and slowed the swimming effort down considerably). I never really felt "bad" narcosis on any portion of the dive and felt pretty good at 160 ft and was able to spear a fish and deal with it, without any difficulties.

I agree with the first part of your comment but for what happened in this dive I think you should have aborted the dive. I think the way of diving deep is : anything not "normal", stop the dive. In this case you had 2 points that were not that good for a deep dive, current and visibility. That is also part of the training (for wetb4igetinthewater: ). But I agree that, as you stated, with time we can get carried away and those "eye opener" can be cruel...

nor any option to 'plan far enough ahead' given their training schedule and their opening schedule.

So you’re saying you failed to plan far enough ahead. You can get a T of He anywhere in the world. It might just be more work than you want to put in.

This reminds me of the guy here on SB who says you can get twinsets anywhere if you plan ahead and there is zero reason to dive side mount in open water. Divers limit themselves with this belief.

It is trivial to back bands and a manifold.

I worked at a dive store for years. Number of tech divers that could assemble their own doubles? MINIMAL.

im curious to know how many self organised expeditions youve made outside of the US? and where?

Ok , I will try . First equipment failures .
Let's assume the diver has to surface from a depth of 50 meters without the possibility of getting air.
Now it depends on how he reacts in this situation. If he gets nervous, it becomes immediately dangerous. On the other hand, the circumstance of not being able to breathe under water, which hopefully a diver knows from freediving, can induces the physiological reaction of reducing CO2 production by the diver minimizing all non-essential physical and mental activities to maintain the necessary calm. This is a prerequisite for meaningful behavior and procedures that need to be executed according to the problem to be solved . And because we are experienced divers here, I don't need to describe them in detail.

Advanced technique: Diving with reduced awareness.
In freediving, I occasionally use a technique that I call 'sleeping,' which also works in scuba diving.
When it might get tight while ascending and I have no obstacles above me, I close my eyes, feel how the water flows around me, say 'water streaming,' and dive into the 'big nothing,' or 'nirvana,' or go to sleep. When I reach the surface, I have saved a lot of energy.
The 'water streaming' is a safety check that is supposed to wake me up if I should stop ascending.
This is just one example, each diver can find out what is useful to thim .

buddy emergency :
The best thing to do here is to intervene in good time before the problems become too big.
There are two very good scales for this in diving .
The best thing is to see and hear the buddy's breathing. This gives you an approximate impression
of his physical and mental state. If you then add the motoric you will not be so easily fooled .
But it is important to note what good breathing is at a depth of 60 m and that is a new topic.

I’ve been involved in getting equipment and vehicles all over the world. If you’ve got the time and money it’s not that hard. Just frustrating.

Wow. I mean, just wow!

 

[tursiops]

Helium is always "available" if you plan far enough ahead and pay what it costs.

Clearly, you've not dived very many places.

 

[old frogman]

Clearly, you've not dived very many places.

Like Okinawa, Kiribati, Tuvalu, Nauru, Marshall Islands, Palau, Vanuatu, Soloman islands, Papua New Guinea. Reason helium not available, high cost and low demand.

If you have very deep pockets, you can have it pre-delivered. Then you have the logistic problem of making trimix blends on site.

I only know one tech diver, where I live, that can pull it off and he is a retired multimillionaire.
