This shows me how important it is to have OC training doing deep dives handling stages. Although it was a longe video, much appreciated for you been honest and giving some good explanation.
It's definitely important to know how to handle stages. One way to achieve that is through the OC route that most CCR divers follow but it is also extensively covered on most CCR courses. Glad you enjoyed the video 👍
Happy for a safe bailout. Thank you for sharing, slow onset issues like that can be difficult to register. Thanks for showing your whole thought process while you were diagnosing and reacting.

Its aldo just a really useful look into the technology and how it works and functions. Great video mate. Also congrats on the plate find. Very cool little trophy !

Super interesting video. Probably will be getting into rebreather diving next year and this was a wonderful real life demonstration of bailout procedures.
Awesome video. Thanks for sharing. Kept your cool, stayed relaxed. Glad it all went smoothly, well the bailout! There is so much real-world information here to use if I ever move to CCR or even more technical diving.
Thanks so much for sharing. I moved to CCR diving a couple of years ago, have about 100 CCR dives and recently completed MOD2 / TEC60. I still consider myself a beginner though! This is so valuable and has given me a lot to think about as I start to plan dives approaching these depths.
Great video and explanation of a rebreather dive event. I'm only a lowly TDI Advanced Mixed Gas Diver and never dove a rebreather, but followed every thing you said and did.
Thanks for commenting and I'm so glad it made sense to you as that was what I was trying to achieve. P.S That's a great qualification you have so I wouldn't knock it!
In your video you have answered all your questions/ problems. All ways dive the unit on just under minimum lope volume that way every breath you take tells you the ppo2/depth and any problems in the lope. Only add diluent manually. This makes the diver more in tune with the Rebreather. It takes work to master it but works
The one reason i like my poseidon mk7 the automatic check sequence. It can be a pain but wont let you dive if the rebreather has an issue. I admire your honesty
There's no doubt that each unit has it's own strengths and weaknesses. Most importantly though they're incredible pieces of technology that allow us to do amazing dives!
Thank you for this very interesting video ! I’am a AP Inspiration diver too. It’s unbelievable that your buddy couldn’t find out where the loop is leaking out the diluent gas! And it’s unbelievable too that you could breathe the gas without any co2 symptoms before you changed to your bailout very late at the deco ? Which great unit the AP Inspiration ist, still working in this conditions !
There is definitely a lot to remember and we are only humans. It’s a testament to your experience that you did not panic and came out of the dive ok. I should imagine that if you came Hypoxic at any depth. You could possibly start making dangerous decisions that could cost you your life. Great video. Glad you are ok . 👍👍👍👍👍👍👍👍👍
Kudos firstly for keeping calm under those circumstances and secondly for sharing the vid and explaining your thought processes and take-aways for the future. This sort of 'real-life' info is always a real help to the CCR & wider dive community. Something which the old dive forums were really good at, back in the day and now seem lost in this faster media age. Also think the use of your Kindle was a good idea. Whilst not strictly trained protocol, anything IMO that maintains a little normality and calmness in those circumstances shouldn't be knocked. I'd have grabbed my mp3 player too !! *Side-note* I had a huge head-on accident on my sportsbike 10 or so years ago and when I returned for my 1st ride back a year later I found myself riding really anxious. I usually ride with some background tunes on but felt that wasn't appropriate on this 1st ride so had them switched off. After 10 minutes I was still anxious so hit 'Play' on my earpieces and was immediately calmed. What works works right ! A couple of thoughts on the dive, absolutely not criticisms, as above I firmly believe everyday is a shared experience day. Was a roll to the right and slight head-down to dump the water into the exhale counterlung an option to maintain some loop integrity ? From the volume accumulated in your scrubber at the end of the dive I suspect you would have had to de-water the c/lung at least once too which could have added to the faff when a B/Out is a 'less-steps' process. Maybe earlier thought when the gurgling started? Your buddy did a great job sticking with you throughout deco, not right up in your face but keeping in close quarters in case you needed assistance. Hat tipped to him too. One thing my buddy and I put into our dive protocols and practice is for if one of use indicates that we are switching to OC/ Bailout then the other diver also ID's and readies their similar bailout gas just in case yours fails just as you shove it in your gob ! Also acts as reassurance that there's another gas source within reach and shows we're on the same page. Some of these bailout tins/ regs don't get much use between inspections ! Lastly I'm also great user of Wetnotes (mostly for rude comms and cartoons of willies !) ... but I do have a pre-printed and laminated sheet in the front of my Wet-Notes with some easy buddy comms questions. i.e. Possible flood please check ... and then numbered options for the failure mode 1) Hose 2) C/lung 3) Scrubber etc... these can then be pointed at or indicated by buddy with number of fingers raised. I have a few other comms questions that can cut straight to the issue and again save faffing. Might be an option for the future Again kudos to all involved, including the attentive skipper and deck hand. Really enjoy these vids - keep 'em coming
@@B12OADY Thanks so much for taking the time to make such a lengthy comment and you make some really good suggestions there. I did try to shift water from the scrubber to the counterlung several times although you can't really see it on the video. It does work a bit but isn't a cure-all and obviously wouldn't have stopped the route cause!
It’s why proper training and staying current comes into play. No panic, the bailout is there, stay calm and everything is fine. I have never dived closed circuit but I have done deep dives on air back in the 80’s when we were often first down on a wreck since it was sunk (narked pretty bad on one) Enjoy watching your vids. Brings back memories of channel wreck diving.
@@D33pUK I had a book published back at the end of the 1990’s called Dorset Shipwrecks, a comprehensive guide to the shipwrecks of Purbeck and Poole Bay. It’s still available on Amazon. A bit out of date as there are wrecks in the book that hadn’t been found at the time and are now dived regularly. Good for the history of the ship and it gives Lat/longs.
@steveshovlar994 I've got a copy! Very handy back in the day but wrecksite.eu is now the tool of choice as it has all the UKHO data on it and is routinely updated.
Thanks for admitting you are human!!!! Lots of armchair divers. You were able to live through it learn from it and help others. The armchair haters can always point fingers. Thank you again for your information
Do you have any more details around caustic cocktails not being an issue anymore (around ~27:00 mark)? I don't believe anything has changed as far as the chemical reaction goes, and I know experienced people who have gotten very serious caustic cocktails in past year or two. The only caveat to this I know of is the pre-packed EACs that e.g. Dive Rite Optimas use are more resilient to this.
A few other people have picked up on this remark which wasn't phrased well at all! What I meant was that most people assume that sea water plus sofnalime produces toxic gas which isn't true. Of course you don't want the liquid to get anywhere near your mouth!
Thanks for taking us along for the ride. Clear explanations and good footage of the incident and your thought processes during each stage, no slipping down the funnel of doom there. Another enjoyable video and self-critique👌
As some one who is knocking on the door to CCR this was super interesting dude! Thanks for sharing. Also takes a big person to admit their mistakes as much as their success’. As you said all round positive outcome and great teamwork. See you Monday, Josh
I had a wry smile on my face when I saw that - was standard equipment for divers when I started in the 80s. Still have mine with the clipping point welded on (but it's been relegated to the shed for standard DIY uses these days)
Hy Thnx for your interesting narration on the vid. May I ask what is your source on "modern sofnolime has no/less caustic cocktail effect"? No blockage on the O2 readings during the dive? The oxygen cells measuring surface doesn't like that much water in the head ;) You stayed on the loop very long, crazy that the sofnolime was still somewhat funtional
Thanks for commenting and there has been quite a bit of chat about this! What I meant was that many people assume that sofnalime produces toxic gas when it reacts with sea water but this isn't the case. It's difficult to say how much water was in the loop when I bailed out but it certainly wasn't full. Remember that I was on OC bailout for approx 60 mins so lots more water will have come in then. I didn't get any cell alarms so think they continued to work ok. I also dried them out and dived them the next day (55m) without any issues. Unfortunately my CO2 sensor was killed by the incident 😭
@@D33pUK Caustic cocktail is more about an extreme alkaline/basic fluid entering your mouth/lungs via the mouthpiece. Never had a damaged CO2 (or dive prematurely ended because of one) since I never had it installed ;) Do you have a tempstick? I flooded my unit once and the alarms coming from the tempstick made it undiveable
Bubble check 6m? Good video, many if not most RB divers would likely be more circumspect about an incident like this. I had a similar experience on the Ouroboros but it was down to the 1st gen spring used on the OP valve being too weak. Boy did I lose dil. So much I had to bailout prior to deco stops. Had Phil Short worried…
Yes you can see the bubble check in the video, although it's obscured by my description of how a RB works. Of course it probably wouldn't have helped as even when I asked two divers to look for bubbles later on neither of them could spot anything.
Appreciate the honesty regarding the pre-dive routine. Relatively new to rebreathers and still religiously going through them on my JJ. I think the most important question though is can we get a video on this waterproof kindle setup of yours? My wetnotes are mostly full of games of hangman my buddy and i have played during longer stops 😂
I've enjoyed your thorough, informative and interesting videos for a few weeks now and look forward to witnessing your adventures. Knowing a little bit about ccr, though the extent of my diving was in a pool, one question that occurs to me is in troubleshooting another diver's gear, buddy or otherwise. Prior to getting wet, do you familiarize yourselves with each other's systems? If not, would this help in any way, or are the distinctions between different makes/models small enough to be inconsequential? Thanks for all that you share with us and glad this situation wasn't worse. Cheers!
@@edbridges1164 Getting stressed rarely helps in situations like that. I'm fortunate that my background has prepared me for this sort of thing and I also have a limited imagination!
This was so interesting! Thank you for sharing the video and the in-depth commentary. Really appreciated! Glad you got out safe. Thanks again for posting this!
Hi @D33pUK, Thank you for your time putting this video together. Could you please explain how are you "not getting caustic cocktail with modern sofnolime". That one sentence caused a bit of a stir in our diving community. 🤔
Yes, a throw away comment that wasn't well worded - lots of discussion about this on FB as well! What I meant was that many people assume that sofnalime produces toxic gas when it reacts with sea water but this isn't the case. For it to become a problem then the liquid needs to reach your mouthpiece and be ingested. Unless you go head down this is unlikely to happen with most CCR designs - I spent approx 20-30 mins on a loop with a reasonable amount of water in it without this happening. Hope that clarifies my comment?
Well done mate. Good on you for having the honesty to post this. Useful info. I have had 3 scares in 2300+ dives. I can only say there is training and then when it happens it is never as smooth as the practices. If you get most of it right you will live but it ain’t always that pretty. Safe diving.
I’ve done successful positive or negative checks then had pressure at depth cause a flood. It happens. I dive a choptima and bailing to OC is easy though
I use an Aquapac mini-tablet case with a Gen 4 Kindle - aquapac.net/products/waterproof-mini-tablet-kindle-case-for-7-8-3-screens I've had this combination down to about 30m without any leaks although the buttons won't work deeper than about 18-20m. My normal procedure is to leave it on the lazy shot/trapeze so it is available when I come back up
Thank you so much for this informative video! I have around 70 dives on my JJ and dream of exploring wrecks like this one. I really appreciate how you narrate and explain your thought process. Do you typically perform a bubble check at 6 meters? Would a thorough negative check help identify the issue before the dive? Thanks again!
JJs are great units and I'm sure you'll progress to deeper dives, if that's what you want. We did a bubble check on the way down (it's hidden behind the 'how a rebreather works' bit of my video) and I'm pretty certain I did pos/negs before getting in the water although can't say for absolute certain.
Thanks and hope you enjoy my other videos. No I didn't get a wet breath or any sort of unusual taste in the loop. As to why, then I'd suggest a few factors - it's quite difficult for liquid to get from the cannister to the mouthpiece and I got off the loop before the cannister became totally flooded.
I'm not a diver although I have done some very basic pool training many years age, my father and a friend, both engineers, made a basic DV using a design in an article in national geographic about Jaque Coustao from biscuit tins and air tanks from surplus glider landing gear air bottle and dived the lake in Sutton Park in Brimingham in there youth! Apparently they only got about three mouthfulls of air before it ran out, but it worked. I found the talk through very interesting and a good analysis of what you did right as well as what you did wrong and how you could improve if it happens again. My engineering observation is, could the outer housing of the rebreather be made of a more transparent so you could see the contact point of the O ring all the way around through it. This would allow you to see any contact failures or 'pipe crossing' in the seal. Would pulling a vacuumn in the system once assembled have shown up the problem? I'm trying to think of an easy way to check the system interigity before you get in the water. Merry Christmas
It's interesting that you mention a transparent cannister which I think is a great idea and I'm only aware of one CCR that has done this. Before getting in the water we do a positive and negative pressue check of the system integrity. This is achieved by blowing/sucking then closing the mouthpiece so not a massive pressure differential but normally quite effective at identifying leaks. I'm pretty sure that I did this before this dive but couldn't say with 100% certainty.
@@D33pUK While a quick suck / blow may show a larger leak it wouldn't show smaller ones which would allow water to slowly accumulate over the dive time, depending on depth. Im thinking of something like the Mityvac Silverline Elite hand pump kit. These are used for pressurising and or pulling a vacummn in car air / water systems. With this you could do both tests but leave them from a few minutes and watch the gauge rise or fall. Having watched a few videos now, it looks like there is an assumption that water is filtered out at the top of the breating loop! In my experience water collects at the bottom of systems. So could a sump be added into the bottom of the scubber container? If this could be if necessary temporarily isolated from the breathing loop and perged, like clearing your mask then put back into the loop. Taking it one step further add a float valve sensor to the electronics to tell the diver he has water in there sooner rather than later. Just blue sky thinking from a position of partial ignornace 🙂
@@cavedivemake5492 Glad you found it useful and yes I've reflected on what I do. I still think I did the pos/neg when I built the unit but I'm certainly more rigorous about it now. If I have to bail out again then I'll also ensure I stay closer to the lazy shot.
Great video. Thanks for sharing. Your approach here reminds me of a concept used in aviation called Just Culture where people put their hands up and highlight their own mistakes for others to learn from for the betterment of the field as a whole. Your experience shone through here in your calm response to a challenge that may well have gotten the better of someone with less experience. Much respect 🫡. It would be great to see a video of your entire kit laid out on dry land with a brief explanation of what everything is and what it does sometime
Thanks, a very long time ago I used to be a military helicopter pilot so I'm used to Just Culture and the principles that surround it. Everyone is human and we can all learn! A video on my kit is in the offing .....
I like the idea of letting out excess gas from the side of the mouth I’ll have to try that next time I dive. I normally just let it out through my nose and everyone I dive with does the same
@ I don’t find it so if I’m honest. Feels fairly natural to be fair just like normal breathing in and out through the nose. But 100% will give the mouth vent a go. Diving Xmas morning next so will try then.
Wow, what an informative dive. I learned a lot about rebreathers and safety procedures. I'm glad that everything worked out and those procedures worked as they were designed to.
@@ee02108 Remember that the scrubber wasnt't completely full when I bailed out, I spent approx 80 mins on open circuit which is when the loop filled completely. I'm sure sofnalime will have limited performance when wet but can't believe it will work well when fully immersed.
sofnolime can handle a little water. Your breath is moist and in fact, the chemical process of removing CO2 creates some moisture too. But cups of water, no.
Since the scrubber was being flooded what about its efficiency absorbing CO2? Should it be concerned since you got aware of the problem with flooded scrubber? Than you for the video, enjoyed it.
Good video. I assume your unit passed Pos/neg before getting in the water. In hindsight, do you think it was wise to stay at (fairly deep) depth with the deco clock ticking when you knew your loop had a fairly large gas leak? As much as rebreathers do give us time to deal with certain issues, things like a loss of loop integrity should be an instant "thumb the dive" as soon as they are realized - especially before big amounts of deco build up. Glad you are ok.
I can't say 100% say but am pretty confident that it did pass the pos/neg. Pretty much every rebreather diver I know has dived with small amounts of liquid in the loop, not least because your lungs naturally produce it! Trying to decide when a small amount becomes 'too much' is the challenge but I agree that I left it too late.
Yep. I get a fair bit of condensation build up in my JJ - especially if cold water diving where I'm fairly sure the moisture condensates in the counter lungs etc at a higher rate. However, water in loop can mean condensation or flooding. Gas out of loop is never normal. Glad you're OK though mate. Out of curiousity - what was your CC TTS when you left the bottom before you bailed? Without rewatching - I assume you are using a Shearwater as your independent computer? Gradients?
And kudos for posting this. There are far too many accidents/incidents that get swept under the rug in our community when they should be shared and learnt from.
Is it the modern scrubber or the modern cannister which allows for this apparently not getting a caustic cocktail phenomenon? i.e. is it a clever way that water can't mechanically leave the cannister, but the wet scrubber is dangerous, OR is it that the wet scrubber itself doesn't produce a caustic, and you potentially got some of that wet scrubber in your mouth while your rebreather was full of water? Thanks for the clarification, just an outside observer trying to understand a bit deeper!
Another informative video. I did a dive to seventy metres on CCR nearly twenty years ago. Boat was full of random people and on the way out to the site everyone's checking each other out and having a chat about the dive. I was in a team of three and we found out one of the other divers was on his own and wasn't carrying any bailout. My mates a CCR Instructor trainer and he starts asking this lad what his bailout plan was, he says he's diving alpinist and if something does happen he's going to take our gas. The reply he got was if you want our gas we're keeping your kit, up to you if you want to dive to that depth with no bailout gas but there's a price for our gas.
I think the 'alpinist' approach has gone out of fashion these days but I know that it used to be relatively common. Personally I only dive with people I know/trust.
@D33pUK it was never that popular for deep dives, especially not beyond fifty metres. When it comes to bail out gas there's no such thing as too much. I usually dive with loads of randoms so carry everything I need.
it is amazing how well this is explained. curious what is that jelly chain creatures floating around.... sofnolime still contains 4% of sodium hydroxide which is extremely well soluble so it must be bad ...
Hello. I am not a CCR Diver. Just AOW with EAN. Planing on Deep Diver next year. I know the substrate needs to be dry. Always wondered how to keep water out of the hoses? Which I am guessing why some have the Integrated Bailout.
Integrated bailout (aka Open Circuit Bailout) don't prevent water getting in the loop but make it easier (arguably) to bailout. OCBs have two modes - Open and Closed Circuit. In Closed Circuit mode, like any other rebreather mouthpiece, an OCB needs to be kept in your mouth otherwise water will enter the loop. In this case the water was coming in through the cannister rather than anywhere near the mouthpiece!
@@D33pUKDuring my AOW Class, The Octo came apart in about 30 feet. While Descending I saw a Burst of bubbles. Looked down and saw the Octo Free Flowing. The Purge Button came out. I was able to stop iot and ascend. The Instructor saw it. Followed me up. Asked if I was 👌. Showed him the Reg. I had to borrow the DM's spare. Sucks is the Reg Set was fairly new. As it only had a couple of dives. Dropped off at the shop. 2 weeks later?? Went to pickup. Tested on a cylinder. Then the First Stage blew out. Had the Octo not come apart, I could've been doing the Deep Diver portion when it happened.
@@chrisphilhower6029 I had a similar experience on my AOW course. Quite shallow, 8m I think, clearing the mouth piece and the purge button blew out. I got a mouth full of water and had first stage free flowing in my face. Switched to my backup reg easy enough (drills!) and signalled my buddy. Switched to my buddies air for saftey stop while the instructor turned my tank off. Gear was hired so I never got an answer as to why, the only comment from the dive shop was don't blow so hard when you clear.
Cracking vid. you kept super cool under what was clearly a potentially deadly situation. Interesting thing for me, this ship was an alan furness withy vessel, my great grandfather (Arthur william hill) was the preferred pilot for that line working out of tilbury. There's a good chance he piloted this ship out on her last voyage. On his obituary it's stated that several of the ships he piloted during ww1 were torpedoed or mined so this could very well be one of them.
@shootingwithmitch5921 Not sure if you've seen my video where I talk about the incredible history of the wreck? th-cam.com/video/AbJGB0EyTOs/w-d-xo.html The East Point was a regular visitor to the Thames so I'm sure your great-grandfather would have been on it!
You need 8 more cylinders and plenty more kit, not sure you have enough. What about the kitchen sink and a boiler. Oh, and a rubber ducky with a PADI open water certificate.
@@Mikesworld777 They're great units and I dive with several people who use one. The automated pos/neg check feature identified a cracked scrubber cannister on a trip I was on a few months ago! I couldn't afford one though 😂
It is the presence of CO2 in your lungs which causes you to automatically breathe in (this is not triggered by lack of oxygen) so CO2 is not all bad! Diluent is a mixture of oxygen & inert gas? Unlike conventional rebreathers which use pure oxygen & are not safe below 33 feet (10 metres) because high partial pressures of oxygen become 'poisonous'.

Only add diluent manually.
This makes the diver more in tune with the Rebreather.

And it’s unbelievable too that you could breathe the gas without any co2 symptoms before you changed to your bailout very late at the deco ?
Which great unit the AP Inspiration ist, still working in this conditions !
They're incredible machines - mine has taken me on some amazing dives and I love it to bits!
Good for you that ended well. Precious educational material, appreciate you shared so we all can learn.

@@daveturton1784 Glad you found it useful - thanks 👍
There is definitely a lot to remember and we are only humans. It’s a testament to your experience that you did not panic and came out of the dive ok. I should imagine that if you came Hypoxic at any depth. You could possibly start making dangerous decisions that could cost you your life. Great video. Glad you are ok . 👍👍👍👍👍👍👍👍👍
Cheers, glad you found it interesting!
Kudos firstly for keeping calm under those circumstances and secondly for sharing the vid and explaining your thought processes and take-aways for the future. This sort of 'real-life' info is always a real help to the CCR & wider dive community. Something which the old dive forums were really good at, back in the day and now seem lost in this faster media age.
Also think the use of your Kindle was a good idea. Whilst not strictly trained protocol, anything IMO that maintains a little normality and calmness in those circumstances shouldn't be knocked. I'd have grabbed my mp3 player too !! *Side-note* I had a huge head-on accident on my sportsbike 10 or so years ago and when I returned for my 1st ride back a year later I found myself riding really anxious. I usually ride with some background tunes on but felt that wasn't appropriate on this 1st ride so had them switched off. After 10 minutes I was still anxious so hit 'Play' on my earpieces and was immediately calmed. What works works right !
A couple of thoughts on the dive, absolutely not criticisms, as above I firmly believe everyday is a shared experience day.
Was a roll to the right and slight head-down to dump the water into the exhale counterlung an option to maintain some loop integrity ? From the volume accumulated in your scrubber at the end of the dive I suspect you would have had to de-water the c/lung at least once too which could have added to the faff when a B/Out is a 'less-steps' process. Maybe earlier thought when the gurgling started?
Your buddy did a great job sticking with you throughout deco, not right up in your face but keeping in close quarters in case you needed assistance. Hat tipped to him too.
One thing my buddy and I put into our dive protocols and practice is for if one of use indicates that we are switching to OC/ Bailout then the other diver also ID's and readies their similar bailout gas just in case yours fails just as you shove it in your gob ! Also acts as reassurance that there's another gas source within reach and shows we're on the same page. Some of these bailout tins/ regs don't get much use between inspections !
Lastly I'm also great user of Wetnotes (mostly for rude comms and cartoons of willies !) ... but I do have a pre-printed and laminated sheet in the front of my Wet-Notes with some easy buddy comms questions. i.e. Possible flood please check ... and then numbered options for the failure mode 1) Hose 2) C/lung 3) Scrubber etc... these can then be pointed at or indicated by buddy with number of fingers raised. I have a few other comms questions that can cut straight to the issue and again save faffing. Might be an option for the future
Again kudos to all involved, including the attentive skipper and deck hand. Really enjoy these vids - keep 'em coming
@@B12OADY Thanks so much for taking the time to make such a lengthy comment and you make some really good suggestions there.
I did try to shift water from the scrubber to the counterlung several times although you can't really see it on the video. It does work a bit but isn't a cure-all and obviously wouldn't have stopped the route cause!
It’s why proper training and staying current comes into play. No panic, the bailout is there, stay calm and everything is fine. I have never dived closed circuit but I have done deep dives on air back in the 80’s when we were often first down on a wreck since it was sunk (narked pretty bad on one) Enjoy watching your vids. Brings back memories of channel wreck diving.
Absolutely!
@@D33pUK I had a book published back at the end of the 1990’s called Dorset Shipwrecks, a comprehensive guide to the shipwrecks of Purbeck and Poole Bay. It’s still available on Amazon. A bit out of date as there are wrecks in the book that hadn’t been found at the time and are now dived regularly. Good for the history of the ship and it gives Lat/longs.
@steveshovlar994 I've got a copy! Very handy back in the day but wrecksite.eu is now the tool of choice as it has all the UKHO data on it and is routinely updated.

Great video! Glad you made it okay.
Cheers!
Do you have any more details around caustic cocktails not being an issue anymore (around ~27:00 mark)? I don't believe anything has changed as far as the chemical reaction goes, and I know experienced people who have gotten very serious caustic cocktails in past year or two. The only caveat to this I know of is the pre-packed EACs that e.g. Dive Rite Optimas use are more resilient to this.
A few other people have picked up on this remark which wasn't phrased well at all! What I meant was that most people assume that sea water plus sofnalime produces toxic gas which isn't true. Of course you don't want the liquid to get anywhere near your mouth!
Thanks for taking us along for the ride. Clear explanations and good footage of the incident and your thought processes during each stage, no slipping down the funnel of doom there. Another enjoyable video and self-critique👌

Great video....thanks!
Tx for sharing.
Thank you for sharing. I am not a CCR user but i dive with CCR buddies. The scrubbers should be equiped with a cell that detects water infiltration.
Hy Thnx for your interesting narration on the vid. May I ask what is your source on "modern sofnolime has no/less caustic cocktail effect"?
No blockage on the O2 readings during the dive? The oxygen cells measuring surface doesn't like that much water in the head ;) You stayed on the loop very long, crazy that the sofnolime was still somewhat funtional
Thanks for commenting and there has been quite a bit of chat about this! What I meant was that many people assume that sofnalime produces toxic gas when it reacts with sea water but this isn't the case.
It's difficult to say how much water was in the loop when I bailed out but it certainly wasn't full. Remember that I was on OC bailout for approx 60 mins so lots more water will have come in then.
I didn't get any cell alarms so think they continued to work ok. I also dried them out and dived them the next day (55m) without any issues. Unfortunately my CO2 sensor was killed by the incident 😭
@@D33pUK Caustic cocktail is more about an extreme alkaline/basic fluid entering your mouth/lungs via the mouthpiece.
Never had a damaged CO2 (or dive prematurely ended because of one) since I never had it installed ;)
Do you have a tempstick? I flooded my unit once and the alarms coming from the tempstick made it undiveable
Bubble check 6m? Good video, many if not most RB divers would likely be more circumspect about an incident like this. I had a similar experience on the Ouroboros but it was down to the 1st gen spring used on the OP valve being too weak. Boy did I lose dil. So much I had to bailout prior to deco stops. Had Phil Short worried…
Yes you can see the bubble check in the video, although it's obscured by my description of how a RB works.
Of course it probably wouldn't have helped as even when I asked two divers to look for bubbles later on neither of them could spot anything.
Appreciate the honesty regarding the pre-dive routine. Relatively new to rebreathers and still religiously going through them on my JJ. I think the most important question though is can we get a video on this waterproof kindle setup of yours? My wetnotes are mostly full of games of hangman my buddy and i have played during longer stops 😂
It's on my to-do list as quite a few people have asked for this!
I've enjoyed your thorough, informative and interesting videos for a few weeks now and look forward to witnessing your adventures.
Knowing a little bit about ccr, though the extent of my diving was in a pool, one question that occurs to me is in troubleshooting another diver's gear, buddy or otherwise. Prior to getting wet, do you familiarize yourselves with each other's systems? If not, would this help in any way, or are the distinctions between different makes/models small enough to be inconsequential?
Thanks for all that you share with us and glad this situation wasn't worse. Cheers!
There are some reasonable differences between units but they aren't that disimilar and we all know enough about them to be helpful underwater
That's what would scare me running into problems! But you seem as calm as a coma there
@@edbridges1164 Getting stressed rarely helps in situations like that. I'm fortunate that my background has prepared me for this sort of thing and I also have a limited imagination!

@@nir890 No problems at all, appreciate you watching it and taking the time to comment 👍
What are those stringy things with what appear to be lumps inside them floating around?
They’re called salps, the next day there were a lot more of them it really helped to pass the time on deco.
en.m.wikipedia.org/wiki/Salp
Hi @D33pUK, Thank you for your time putting this video together. Could you please explain how are you "not getting caustic cocktail with modern sofnolime". That one sentence caused a bit of a stir in our diving community. 🤔
Yes, a throw away comment that wasn't well worded - lots of discussion about this on FB as well!
What I meant was that many people assume that sofnalime produces toxic gas when it reacts with sea water but this isn't the case. For it to become a problem then the liquid needs to reach your mouthpiece and be ingested. Unless you go head down this is unlikely to happen with most CCR designs - I spent approx 20-30 mins on a loop with a reasonable amount of water in it without this happening.
Hope that clarifies my comment?
Well done mate. Good on you for having the honesty to post this. Useful info. I have had 3 scares in 2300+ dives. I can only say there is training and then when it happens it is never as smooth as the practices. If you get most of it right you will live but it ain’t always that pretty. Safe diving.
Thanks!
I’ve done successful positive or negative checks then had pressure at depth cause a flood. It happens. I dive a choptima and bailing to OC is easy though
Hi, fantastisk video! Just one question, how do you pack a Kindle before a dive? How deep do you take it and what housing are you using?
I use an Aquapac mini-tablet case with a Gen 4 Kindle - aquapac.net/products/waterproof-mini-tablet-kindle-case-for-7-8-3-screens
I've had this combination down to about 30m without any leaks although the buttons won't work deeper than about 18-20m. My normal procedure is to leave it on the lazy shot/trapeze so it is available when I come back up
@@D33pUK Fantastic, thanks!! Looking forward to try this on next deep dive
Thank you so much for this informative video! I have around 70 dives on my JJ and dream of exploring wrecks like this one. I really appreciate how you narrate and explain your thought process. Do you typically perform a bubble check at 6 meters? Would a thorough negative check help identify the issue before the dive? Thanks again!
JJs are great units and I'm sure you'll progress to deeper dives, if that's what you want.
We did a bubble check on the way down (it's hidden behind the 'how a rebreather works' bit of my video) and I'm pretty certain I did pos/negs before getting in the water although can't say for absolute certain.
You got a sub! Great content.
Why didn't you get a wet breath or wet sorb caustic feeling?
Thanks
Thanks and hope you enjoy my other videos.
No I didn't get a wet breath or any sort of unusual taste in the loop. As to why, then I'd suggest a few factors - it's quite difficult for liquid to get from the cannister to the mouthpiece and I got off the loop before the cannister became totally flooded.
Enjoyed the video, my wife has banned me from re-breathers but a man can still dream ...
I can always remember my wife asking how long we'd owned the rebreather in the garage 🤣
I'm not a diver although I have done some very basic pool training many years age, my father and a friend, both engineers, made a basic DV using a design in an article in national geographic about Jaque Coustao from biscuit tins and air tanks from surplus glider landing gear air bottle and dived the lake in Sutton Park in Brimingham in there youth! Apparently they only got about three mouthfulls of air before it ran out, but it worked.
I found the talk through very interesting and a good analysis of what you did right as well as what you did wrong and how you could improve if it happens again.
My engineering observation is, could the outer housing of the rebreather be made of a more transparent so you could see the contact point of the O ring all the way around through it. This would allow you to see any contact failures or 'pipe crossing' in the seal. Would pulling a vacuumn in the system once assembled have shown up the problem? I'm trying to think of an easy way to check the system interigity before you get in the water.
Merry Christmas
It's interesting that you mention a transparent cannister which I think is a great idea and I'm only aware of one CCR that has done this.
Before getting in the water we do a positive and negative pressue check of the system integrity. This is achieved by blowing/sucking then closing the mouthpiece so not a massive pressure differential but normally quite effective at identifying leaks. I'm pretty sure that I did this before this dive but couldn't say with 100% certainty.
@@D33pUK While a quick suck / blow may show a larger leak it wouldn't show smaller ones which would allow water to slowly accumulate over the dive time, depending on depth. Im thinking of something like the Mityvac Silverline Elite hand pump kit. These are used for pressurising and or pulling a vacummn in car air / water systems. With this you could do both tests but leave them from a few minutes and watch the gauge rise or fall. Having watched a few videos now, it looks like there is an assumption that water is filtered out at the top of the breating loop! In my experience water collects at the bottom of systems. So could a sump be added into the bottom of the scubber container? If this could be if necessary temporarily isolated from the breathing loop and perged, like clearing your mask then put back into the loop. Taking it one step further add a float valve sensor to the electronics to tell the diver he has water in there sooner rather than later. Just blue sky thinking from a position of partial ignornace 🙂
That amazingly ungraceful entrance into the water actually loosened one of my front teeth!
A very informative well made video, had it made you think of chamging anything with regard to deepe/ longer dives ?
@@cavedivemake5492 Glad you found it useful and yes I've reflected on what I do. I still think I did the pos/neg when I built the unit but I'm certainly more rigorous about it now. If I have to bail out again then I'll also ensure I stay closer to the lazy shot.
Great video. Thanks for sharing. Your approach here reminds me of a concept used in aviation called Just Culture where people put their hands up and highlight their own mistakes for others to learn from for the betterment of the field as a whole. Your experience shone through here in your calm response to a challenge that may well have gotten the better of someone with less experience. Much respect 🫡. It would be great to see a video of your entire kit laid out on dry land with a brief explanation of what everything is and what it does sometime
Thanks, a very long time ago I used to be a military helicopter pilot so I'm used to Just Culture and the principles that surround it. Everyone is human and we can all learn!
A video on my kit is in the offing .....
I like the idea of letting out excess gas from the side of the mouth I’ll have to try that next time I dive. I normally just let it out through my nose and everyone I dive with does the same
Really, that sounds quite uncomfortable especially on long ascents! Let me know how you get on with the mouth technique?
@ I don’t find it so if I’m honest. Feels fairly natural to be fair just like normal breathing in and out through the nose. But 100% will give the mouth vent a go. Diving Xmas morning next so will try then.
Wow, what an informative dive. I learned a lot about rebreathers and safety procedures. I'm glad that everything worked out and those procedures worked as they were designed to.
Glad it was helpful and you enjoyed it!
Very good vid! One question: Does softlime still work when it is full of water?
@@ee02108 Remember that the scrubber wasnt't completely full when I bailed out, I spent approx 80 mins on open circuit which is when the loop filled completely.
I'm sure sofnalime will have limited performance when wet but can't believe it will work well when fully immersed.
sofnolime can handle a little water. Your breath is moist and in fact, the chemical process of removing CO2 creates some moisture too. But cups of water, no.
Hey if you ever get back to me or if anyone knows what those stream looking particle arms are. I can't really tell what those are
They're salps - en.wikipedia.org/wiki/Salp
For whatever reason there was a lot of them around this year!
Why there are no manometers with sound/visual indication of too low pressure of sth?
Since the scrubber was being flooded what about its efficiency absorbing CO2? Should it be concerned since you got aware of the problem with flooded scrubber?
Than you for the video, enjoyed it.
Good video.
I assume your unit passed Pos/neg before getting in the water.
In hindsight, do you think it was wise to stay at (fairly deep) depth with the deco clock ticking when you knew your loop had a fairly large gas leak?
As much as rebreathers do give us time to deal with certain issues, things like a loss of loop integrity should be an instant "thumb the dive" as soon as they are realized - especially before big amounts of deco build up.
Glad you are ok.
I can't say 100% say but am pretty confident that it did pass the pos/neg.
Pretty much every rebreather diver I know has dived with small amounts of liquid in the loop, not least because your lungs naturally produce it! Trying to decide when a small amount becomes 'too much' is the challenge but I agree that I left it too late.
Yep. I get a fair bit of condensation build up in my JJ - especially if cold water diving where I'm fairly sure the moisture condensates in the counter lungs etc at a higher rate.
However, water in loop can mean condensation or flooding. Gas out of loop is never normal.
Glad you're OK though mate. Out of curiousity - what was your CC TTS when you left the bottom before you bailed? Without rewatching - I assume you are using a Shearwater as your independent computer? Gradients?
And kudos for posting this. There are far too many accidents/incidents that get swept under the rug in our community when they should be shared and learnt from.
Is it the modern scrubber or the modern cannister which allows for this apparently not getting a caustic cocktail phenomenon? i.e. is it a clever way that water can't mechanically leave the cannister, but the wet scrubber is dangerous, OR is it that the wet scrubber itself doesn't produce a caustic, and you potentially got some of that wet scrubber in your mouth while your rebreather was full of water? Thanks for the clarification, just an outside observer trying to understand a bit deeper!
@@snared_ It's modern sofnalime which just doesn't seem to react to water that older sofnalime did. If it did I would have bailed out much earlier!
Another informative video. I did a dive to seventy metres on CCR nearly twenty years ago. Boat was full of random people and on the way out to the site everyone's checking each other out and having a chat about the dive. I was in a team of three and we found out one of the other divers was on his own and wasn't carrying any bailout. My mates a CCR Instructor trainer and he starts asking this lad what his bailout plan was, he says he's diving alpinist and if something does happen he's going to take our gas. The reply he got was if you want our gas we're keeping your kit, up to you if you want to dive to that depth with no bailout gas but there's a price for our gas.
I think the 'alpinist' approach has gone out of fashion these days but I know that it used to be relatively common. Personally I only dive with people I know/trust.
@D33pUK it was never that popular for deep dives, especially not beyond fifty metres. When it comes to bail out gas there's no such thing as too much. I usually dive with loads of randoms so carry everything I need.
it is amazing how well this is explained. curious what is that jelly chain creatures floating around.... sofnolime still contains 4% of sodium hydroxide which is extremely well soluble so it must be bad ...
what are those creatures all over around 43:30 ???

Hello. I am not a CCR Diver. Just AOW with EAN. Planing on Deep Diver next year. I know the substrate needs to be dry. Always wondered how to keep water out of the hoses? Which I am guessing why some have the Integrated Bailout.
Integrated bailout (aka Open Circuit Bailout) don't prevent water getting in the loop but make it easier (arguably) to bailout. OCBs have two modes - Open and Closed Circuit. In Closed Circuit mode, like any other rebreather mouthpiece, an OCB needs to be kept in your mouth otherwise water will enter the loop.
In this case the water was coming in through the cannister rather than anywhere near the mouthpiece!
@@D33pUKDuring my AOW Class, The Octo came apart in about 30 feet. While Descending I saw a Burst of bubbles. Looked down and saw the Octo Free Flowing. The Purge Button came out. I was able to stop iot and ascend. The Instructor saw it. Followed me up. Asked if I was 👌. Showed him the Reg. I had to borrow the DM's spare. Sucks is the Reg Set was fairly new. As it only had a couple of dives. Dropped off at the shop. 2 weeks later?? Went to pickup. Tested on a cylinder. Then the First Stage blew out. Had the Octo not come apart, I could've been doing the Deep Diver portion when it happened.
@@chrisphilhower6029 Sorry to hear about your bad experience but kudos to your DM who made sure it all ended up ok.
@@chrisphilhower6029 I had a similar experience on my AOW course. Quite shallow, 8m I think, clearing the mouth piece and the purge button blew out. I got a mouth full of water and had first stage free flowing in my face. Switched to my backup reg easy enough (drills!) and signalled my buddy. Switched to my buddies air for saftey stop while the instructor turned my tank off. Gear was hired so I never got an answer as to why, the only comment from the dive shop was don't blow so hard when you clear.
Cracking vid. you kept super cool under what was clearly a potentially deadly situation. Interesting thing for me, this ship was an alan furness withy vessel, my great grandfather (Arthur william hill) was the preferred pilot for that line working out of tilbury. There's a good chance he piloted this ship out on her last voyage. On his obituary it's stated that several of the ships he piloted during ww1 were torpedoed or mined so this could very well be one of them.

👏👏👏👏
It is the presence of CO2 in your lungs which causes you to automatically breathe in (this is not triggered by lack of oxygen) so CO2 is not all bad!
Diluent is a mixture of oxygen & inert gas?
Unlike conventional rebreathers which use pure oxygen & are not safe below 33 feet (10 metres) because high partial pressures of oxygen become 'poisonous'.
