Ist and 2nd stage serviced regularly. Key pt. Great video. We were on a dive once not very deep, like 20m, three of us. Good viz, I heard a crack, turned around and just saw a cloud of bubbles coming out of the high pressure end at the gauges of one of us. The diver of this unit, was just staring at me and the other guy; of course her gauge read zero air now and I asked if ok, they said yes and I gave them my occi reg.I tried to tie a knot in her hose to slow the air loss but of course this was very difficult. We then made out ascent. We had to have a stop for out particular time. Bt the time we surfaced her tank was basically empty as almost nothing could be urged from her reg. it was interesting.
Very helpful skills and answers to questions that some of us have had for years - like breathing through the hose or directly from a tank! Thank you.
Thanks Steve. As always great info, may save someones life by knowing something that you may not think of at the time.
Great info in this video. It actually answered some questions that I've been pondering for some time. Cheers, Q
Total respect to you Steve 👍🏾, would like to dive with you someday
Thanks Steve !
Thanks, answered some questions that I have often thought about
Hey Steve. Enjoy your videos - very well produced and presented. In this case, you can breath from an lp regulator hose by crimping the hose, then sipping. It works best with rubber hoses, but I've done it with flex hoses as well. I would only do this if absolutely necessary, as with the deco bottle. Divers should also carry enough air to cover decompression if the deco bottle fails. Switching out first stages would really be a last resort, but worth noting. Also, a diver who does not maintain his/her personal regulators should not be diving, especially deco regs. And yes, a basic understanding of reg. repair should be taught to all divers (clearing sand, etc.)
Man I do agree with you, I have had the same questions and some of the situations in real 2009 and I answered exactly the same more or less but off course others who wanna rain you down says a non answered question which is " what if " thanks mate for the video I do appreciate it.
Thanks! Great video
Very good, I did my tdi adv tri mix with Aaron Bruce, being a toolmaker I made him lots of gadgets which I would say he still has today...Keep up you videos Tim
Excellent video!!!
Great stuff many thanks
Bad ass skills! Calm comes from knowledge, preparation and practice.
Great Video ! thank you
Great explanation and nice tips. Thanks
Wow! Really good info... Thank you
nice you just got a new subscriber awesome info
very god video. thank you . ive learn a lot
Well that was very informative! I remember watching 47 meters down with a bunch of friends on a scuba placement and remember seeing the bits where the people trapped underwater end up swapping the first stages onto different tanks... Didn't think it would be possible (especially since it's a hefty beer fine to leave the dust cap off when washing the regs) but what you describe makes sense to me.
(It occurs to me that the film makes literally no sense in many ways, they wear full-face regulators to allow for dialogue and exposition underwater but I don't think this would work with that kind of kit)
Don't mean to say that's all I learned, it's very cool to see some of the skills used in tec diving and certainly food for thought... I dived with a guy using sidemount once and I'll admit it's got it's uses and advantages... Certainly worth consideration if I was to go for getting my own BCD in the next few years...
thanks very educational
Very informative. Very useful to know.
Subbed. This is really good info.
Is a very good tip brother thank's
Wow. Been diving for 13 years and never knew you could detach both stages underwater
You can do it in an emergency, but you'll need to have the first and second stages serviced ASAP afterward, as you will have gotten seawater in the works.
Yes, but if you do you have to have it service right after the dive. He mentioned this in the video too. Same as someone putting first stage in soak tank and not putting dust cap on.
Thank you sir
Never hold your breath Rule #1.
;-)
Great video
I always thought you could breathe from a low pressure hose or tank as a last resort, but this video proves it's not worth it. Thanks for making a video about it so we do not have to.
Garrett K Yes... You can do it!! I learned how to do this in my commercial dive training here in Brazil. But it’s the last of the last’s resources!! Actually you will never need to do that!! You have at least 2 regs, plus 2 from your buddy! What are the odds the all 4 regs broken some way that doesn’t pass any air from it!?
Nice video! Good information.
As an annomily in my training I've taught myself to sip off a cylinder while feathering the valve for upwards of 20 minutes at a time. As expertly stated in the video it isn't a likely scenario nor a plan A contingency. However, it can and has been done and I'm grateful I have it in my tool box when Murphy goes diving with me.
Spared ~ Not likely to happen means it will and chances are will kill you if not prepared. You are right on track. Prepair for the worst hope for the best. But those who train in hell aren't effected by the heat if ya know what I mean. :)
Rest in peace cam. Good to catch one of your old comments, we miss you.
The guys in my shop like to mess around and breathe directly from tanks in the pool to build comfort.
Hi, I think the info is great! Thanks a lot. Can you tell me, technically speaking, what does "the regulator of death" means? Thanks
👏🏻👏🏻👏🏻👏🏻
GOOD INFO
Glad it was helpful!
If I may explain why breathing directly from a low-pressure hose or a cylinder valve is not "practical":
The hose going to your regulator delivers approximately 9.3 bar (135 psi) of air pressure, and the cylinder valve on a low-pressure (LP) steel cylinder can deliver up to 179 bar (2,600 psi) of air pressure. To put this into perspective, it only takes 0.7 bar (10 psi) of positive air pressure to cause massive lung damage.
"So how come our regulators don't blow out our lungs?"
Because they only deliver the amount of air that we need to breathe at the depth/pressure we are currently diving at. The deeper we go, the great the air pressure that our regulators will deliver to compensate for the changes in atmospheric pressure. This is why they are called "regulators" - they regulate the air pressure based on the depth that we are diving at. This also points out why the "regulator of death" drills are so important in technical dive training. If a technical diver does know how to breathe off a compromised regulator, they may find themselves in big trouble one day.
what do u preferred scubapro or Apeks regulator ?
Yes yes an yes
Billy deans in key west ...who was the first instructor to teach trim I'd back in 1991 had his Paul ryles swoping regulator at a deco stop constantly for 3 months and apart from once when the o ring had dropped out they never had a problem ....all the regulators were scubapro mk2 s or sherwood Bruts ...unbalanced 1st stages !!......this was over 25 years ago !!
Master diver, E.R.Cross, had done thev’technifscts column in ‘ Skin Diver ‘ magazine,which no longer publishes , as PaulTzimolis is gone.
Hey Steve...I have a question..while diving the mouth piece of the regulator stayed in my mouth and the valve was detached. The instructor is saying me it happened due to chewing. is it possible?
Which manufacturer best cold water regulators? Thnk you!
Apeks and Scubapro, do very good cold water regualtors
💛💜💙❤💚
Lol I’ve never dived before so I have to ask…. That really happens lol I mean I know it can but does it really? Breathing with the mouthpiece when the hose comes out lol laughing at myself already cause I can see myself doing dim dumb shit like this but laughin at myself after… just like I am nw
Shouldn't divers drill on these techniques before they go real world? Not judging I really haven't any practical expertise to draw from so was just curious. Training for worst case until everything is locked into the divers muscle memory would seem like it should a prerequisite. Maybe the miliatry just made me overly obsessed with precision and preparation i don't know. Anyways love the video's I'm getting to learn allot :) :)
Joe Smith Not necessary for most recreational diving as there are existing redundancies built into the system and concept ( back up second stage and buddy( ies) at depths not necessitating decomression. But hey...the more you know...
Trimix
What your mask brand?
My mask is a Aqualung Ventura Plus
In my PADI instruction I learned to breathe from a freeflowing regulator. Just left one side of the mouthpiece out of your mouth and let the excess air escape. And pay close attention to your air, cause it will depleat the cilinder in a breaze. Another thing, I notice at 2:30 that you inhale, let a bit of air escape and hold your breathe. In spite you let some air escape, shouldn't you keep a little flow of bubbles escaping from your lungs? I know you have a superb buoyancy control, but...
Letting the free flow continue unabated is okay for a rec diver that doesn't need a decompression stop, but a tec diver MUST have enough gas in the tanks to stay at each stage for the required time. The only way to not drain the tank if the regulator free flows is to manually turn the valve off and on as shown here. (And don't worry about holding your breath for a bit if you're not ascending. The "always release a stream of bubbles" myth is for the safety of absolute beginners and so the instructor can see what's happening, but a meter or less of depth change isn't going to risk barotrauma unless you're holding a REALLY deep breath.)
Nuno Girão if you are diving for recreation in a shallow dive yes its applicable. However these tec diving is much more complicated that you need to have more sophisticated air management. Letting your deco tank free flow, you will ran out of air very soon. Consider the depth these tec divers are doing.
2:40 holding his breath???
It's not dangerous if you stay at the exact same depth.. If you start to go up however, then that would be a very bad thing to do. That's is why they teach you to release bubbles . Both for your sake, and for the teacher. The teacher then can see that you aren't holding your breath. New students are not in general very good at buoyancy that is why this is very important.
Mah....
+++++
When gas that ever happened in a dive with twins just isolate the valve buddy breath you have 3 regulators and your dive partner has the same this video makes no sense unless cave diving solo good trim by the way
Rebreathers are regulator s of death.Breathing directly from a tank or l.p.hose is stupid.Buddy breathing mis safer.
