Rebreather diver here, excellent video. Very clearly shows the ability and time availabile to sort out problems. A problem should not mean panic, redundancy means solutions. Great job!
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.

As an OC diver looking into getting into technical diving, I found this incredibly useful as a great learning experience of what can happen and how to remain calm and bail out safely. 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 !

Wow, you really kept me on the edge of my seat. And I am not even a diver myself...! Thank you you for telling hour story, I'm glad you got out of that situation unharmed.
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 👍
@ it is, but it’s still not the same? If you know what I’m thinking about. Ok you train it intens during ccr course. But having done a ton of OC deep dives I’m pretty sure doing it on ccr is going to be more relaxed.
@ I do have a question, didn’t you tasted the caustic cocktail being formed? Seeing how much water was in the scrubber 😅 Does show also how good the unit is, just dry and next day dive again
@@stevedenruyter4902 No sign of a caustic cocktail reaching the mouthpiece despite being on the loop for quite a while. They're fantastic bits of kit and revy resilient!
of course another dive talk fan here, so happy to hear you're okay. You should do a response talking about the things they brought up. They had a lot of positive things to say IMO.
Welcome and hope you enjoy my channel. It was fascinating to hear what Gus and Woody had to say and alos pleasing that they generally agreed with/understood my decision making!
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.
New subscriber, I’m here after watching on Dive Talk. Thanks for sharing your experience and so candidly. I’m looking forward to going through your previous vids. Can’t imagine having such a massive deco obligation whilst my kit was compromised!
Thanks and I hope you enjoy them! In my view, if you do this sort of diving then you have to be prepared for the consequences of bailing out and doing a lot of decompression open circuit. I fyou're not then it's probably not for you!
Thank you for sharing your experience so clearly and honestly. There's a lot that can be learned from the incident for anyone diving or buddying a rebreather diver. Your dive team's emergency protocol is well worth considering. Having your thought processes narrated was also a big bonus. I can identify with all of that. As to the pre-dive preparation, well the checklist thing is very useful and gives reasonable confidence in the integrity of the rebreather. But stuff can always happen to even the best prepared. Very glad you got out safe and well 👍👍
The limit of my knowledge on rebreathers came from this video, but I found it both incredibly fascinating and informative. You balanced the technical information and the human understanding of an emergency perfectly. Glad you are ok and I wish you the best!
Great video. Appreciate your honesty and reflections and I think you did a great job on stayiing on the loop, then doing a nice bailout. Well done to the James's also! I would disagree on your comment that modern sorb can't give a dangerous caustic cocktail; I've seen serious injuries fom ingested/inhaled Sofnolime 797.
Yes I phrased that very badly. What I meant was that lots of people assume you're going to get toxic gas which doesn't happen. Obviously you don't want the liquid anywhere near your mouth!
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.
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!
Thank you for sharing this real world scenario in such detail and honesty 🙏🏼 @33:55 Things can actually happen very quickly on a rebreather! Once for example, I started sinking while photographing a giant jellyfish in open water. In a bulky kit, drygloves and holding a camera, correcting this was surprisingly slow compared to the acceleration of my unplanned descent. Having unwisely switched closed my ADV earlier, in less than a couple of seconds my loop shrunk to nothing, and I couldn't breathe at all. I hit the bottom far below, lungs squeezed empty, before my fumbling around finally located things in the following order: 1) BOV, 2) suit inflate, 3) wing inflate, 4) ADV slider. This was fortunately a minor inconvenience in the end, but definitely be aware that anything affecting breathing, safety of the loop gas, or rapid changes in buoyancy or depth is not a 'plenty of time' situation!
No problems at all. I'm sure anyone who has dived with their ADV closed will agree that it isn't a particularly pleasant experience. Good skills on overcoming it although when I've had the same I've always found that finning upwards buys enough time to get more gas in your loop?
@@D33pUK yes this was a particularly awkward case, including delays due to reaching around for the ADV slider for a bit too long 😄But I worry if such things could occur in an actually challenging or stressful situation, currents, other problems etc. Calm is good, but good reactions could be measured in seconds rather than minutes!
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
Super interesting video. Probably will be getting into rebreather diving next year and this was a wonderful real life demonstration of bailout procedures.
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!
I'm not a diver (yet!) but that was really good information. I think as we become very good at something we can become complacent. I know this from personal experience, I'm a very experienced climber and I had a major accident in a climbing gym where my distraction caused me to forget to clip to a auto-belay system and I jumped thinking I was attached! Thank you for sharing this story so we can all make sure that we always stay aware of everything specially as we become more experienced.
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
I only dove 1 time to 10meter but do understand the basics of rebreathers it was a very cool video and very informative good luck on your next dives. I hope to be diving more in the future to
Glad James didn't go "Street Fighter" mode on the dolphins with his crowbar when they spooked him. Good to see a positive end result and glad you have a good group that have each other's backs.
Great narrative throughout the dive. Yes, we can all say you should have done this or that but what you showed is that staying calm makes for a pleasant outcome. Being a long term CC diver myself it’s always good to know that your options are numerous and it’s highly unlikely that any eventuality would require a bolt up to the surface. Well done.
Excellen video - 1000 * Thx! Cool and competent reaction, very good illustration of the insidious mess of some failures. Happy that you are safe. It is also the curse of a (almost too) well performing ADV. the Us navy mk 15 and 15.5 might be a decent compromise, it has a simple (low performing) schrader valve as ADV which you will notice when it has to be activated. In my (humble) opinion the depth change controlled ADV function on the (very very rare) Interspiro DCSC (now succeed by IS-mix) is the best existing since it will not react to the insidious leak. On the other hand it works best on a semi-closed RB, not a fully closed (-: /Teknosofen - RB diver since 1989
Thanks for the suggestion although I'm very happy with my unit (AP Inspiration). I think all complex systems have the potential to fail although this certainly wouldn't catch me out again!
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.
let cool heads prevail!!!! what a great example of this cliché, i cant imagine what would have happened if you panicked, well I can actually, fantastic demonstration of preparedness and redundance and protocol at work as they should be, seen too many of these clips where the outcome was death, well done mate and well narrated, love youe work
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!
As a beginning diver (just got my OW this year, planning to get AOW in the next couple of months), thanks for all the detailed explanation of technical concepts.
A quite brilliant debrief of a dive gone wrong. Personally, had I been your buddy, I’d not let you abort and go for an ascent and not stick with you. I’m not going to stay on the wreck only to learn you’ve suffered some terrible fate. Good on James RedBare for taking over as your buddy and sticking with you to the end, although again, I’d have insisted you get out first given you’d had the problem. Just the way I operate. So pleased you go back and without a lungful of caustic cocktail, as ultimately, the Buddie uses a similar soda lime scrubber, presumably Sonolime or Intersorb?
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 . 👍👍👍👍👍👍👍👍👍
James is suffering bubble blindness, our thoughts and prayers are with him and his family in this difficult time. Not all men can always spot bubbles, for James though, it seems to be an extra struggle, luckily I think there are drugs for this nowadays that give you longer, harder, stronger bubble spotting powers :P Don't let bubble blindness strike you down lads!
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👌
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 !
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
Glad it went well in the end. You say you could have done things differently but at the end of the day. Hindsight is a wonderful thing. Didnt know Toby Tarrant did scuba 😂 you sound just like him.
It could be good idea (both for owners and producer)to make few small holes in reb cover so in case of gas leakage it can be seen immediately and preventing gas from cumulating under the cover and disrupting bouyancy.
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 .....
@@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!
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)
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.
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.
I've got to be honest I didn't do it when I was actively diving years ago, but I remember from some old school BSAC stuff they used to recomend a "bubble check" at about 6m whilst descending. I wonder if it might be worth reinstating this practice. I admit that it wasn't part of what I used to do but I did pick up my buddy's open circuit primary bubbling on one occasion. I agree with you if you're changing depth alot spotting your ADV going off is going to be very hard. I work in medicine and also was involved in retrieval, I'm not a rebreather diver but watching aircrew do checklists made me realise that it's not just about doing the checklist but HOW you do the checklist - doing the checklist as a 2 person check where one person checks and one person does the check - this means that the checklist is definitely completed and both of you will remember doing it or not afterwards. Just out of interest what was your equivalent air depth when all this was going on? Only thing I think you could have done a bit better was give a clear hand signal - I have a problem which all divers are going to respond to seriously - then they'd have paid much more attention to the wetnotes and your unit. I wonder if it would be a good idea to have a line to clip the gass line to the lazy shot which would prevent you becoming separated. All in all though well managed there's always some things to learn from everything but well done calling the dive and going through it all so well!
Some good points there and thanks for contributing. You can't see the bubble check because it is under the 'how a rebreather works' bit at the beginning. I'm an ex-Army helicopter pilot and we did 2 person checklists during emergencies. Not really as relevant when you're building a CCR as there is unlikley to be anyone else around when that is happening. Ticking each item off is a way to achieve the same by yourself. Narcosis is rarely a problem for CCR divers as we can dive high % helium mixtures without really worrying about the cost. I was on 15/60 which has an EAD of 14m/ END of 22m at 68 metres! On the subject of hand signals, you can't really see them on my video as many of them are out of shot of the helmet mounted camera. I agreed that clipping the deco cylinders to the lazy shot would have reduced the chance of me getting separated although noting that I abandoned it once I had transferred the 100% mix from the line to my person.
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
Tanks für this Video It is a good opportunity to learn from the failures of others. To think other possibilities that can make you a better buddy 4:28
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.
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 😂
A small amount of moisture is required to allow the sofnalime to work and breathing also produces quite a lot of moisture so a water detector would register lots of false positives!
@@D33pUKperhaps some kind of float like in a toilet tank that would only be actuated by quite a volume of water. The difficulty would be deciding what orientation to place it in, unless there was one each in the vertical and horizontal directions.
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.
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.
@ I give the breathing from the side of my mouth on my Xmas dive and I’ll be honest with you I much prefer to vent from my nose. This was from a depth of 40m. Feel like I had more control with it out of my nose.
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?

The limit of my knowledge on rebreathers came from this video, but I found it both incredibly fascinating and informative. You balanced the technical information and the human understanding of an emergency perfectly. Glad you are ok and I wish you the best!
Thanks for the feedback and I really appreciate you taking the time to comment!
Cool as a cucumber my friend, hats off to you. Thanks for sharing and I hope you have a good Christmas mate. All the best from Somerset 👍🏻👍🏻💯✨
Cheers!
This is an absolutely useful and interesting video to watch and a very good emergency procedure thank you for sharing the experience
well managed .
Gla dyou enjoyed it and found it interesting/useful
Great video. Appreciate your honesty and reflections and I think you did a great job on stayiing on the loop, then doing a nice bailout. Well done to the James's also! I would disagree on your comment that modern sorb can't give a dangerous caustic cocktail; I've seen serious injuries fom ingested/inhaled Sofnolime 797.
Yes I phrased that very badly. What I meant was that lots of people assume you're going to get toxic gas which doesn't happen. Obviously you don't want the liquid anywhere near your mouth!
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.
You did not panic.. .. well done...I'm not a driver. But I love all you vidos .verry interesting to woch
Great, glad you enjoy them!
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!
Thank you for sharing this real world scenario in such detail and honesty 🙏🏼
@33:55 Things can actually happen very quickly on a rebreather!
Once for example, I started sinking while photographing a giant jellyfish in open water. In a bulky kit, drygloves and holding a camera, correcting this was surprisingly slow compared to the acceleration of my unplanned descent.
Having unwisely switched closed my ADV earlier, in less than a couple of seconds my loop shrunk to nothing, and I couldn't breathe at all. I hit the bottom far below, lungs squeezed empty, before my fumbling around finally located things in the following order: 1) BOV, 2) suit inflate, 3) wing inflate, 4) ADV slider. This was fortunately a minor inconvenience in the end, but definitely be aware that anything affecting breathing, safety of the loop gas, or rapid changes in buoyancy or depth is not a 'plenty of time' situation!
No problems at all.
I'm sure anyone who has dived with their ADV closed will agree that it isn't a particularly pleasant experience. Good skills on overcoming it although when I've had the same I've always found that finning upwards buys enough time to get more gas in your loop?
@@D33pUK yes this was a particularly awkward case, including delays due to reaching around for the ADV slider for a bit too long 😄But I worry if such things could occur in an actually challenging or stressful situation, currents, other problems etc. Calm is good, but good reactions could be measured in seconds rather than minutes!
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
My pleasure and, like every other human being, I'm not perfect but I hope that the video will help others learn from my experience!
This is absolutely brilliant. As a new ccr diver it is great to experience this as you explain everything step by step. Fantastic. Cheers.
@trevorduncan9635 Glad it was useful and good luck with your CCR journey!
Super interesting video. Probably will be getting into rebreather diving next year and this was a wonderful real life demonstration of bailout procedures.
Enjoy - going CCR will transform your diving!
That was amazing No panic at all. Well done you and your buddy James. Nice that you shared your thoughts along the dive. Sh1t can happen.
Absolutely, I've seen some incredible divers have issues but it's what they do after that which really counts!
wow. I admire how calm and rational you are. As a beginner CCR user I enjoyed the heck out of this video. Thanks for sharing your thought process.
@@andrewxbg No worries at and glad you've found it interesting/useful. Worth noting that others may disagree with elements of my decision making.
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!
I'm not a diver (yet!) but that was really good information. I think as we become very good at something we can become complacent. I know this from personal experience, I'm a very experienced climber and I had a major accident in a climbing gym where my distraction caused me to forget to clip to a auto-belay system and I jumped thinking I was attached! Thank you for sharing this story so we can all make sure that we always stay aware of everything specially as we become more experienced.
Absolutely agree, complacency is always something to guard against. Sorry to hear about your accident and hope for a quick recovery 👍
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
I only dove 1 time to 10meter but do understand the basics of rebreathers it was a very cool video and very informative good luck on your next dives.
I hope to be diving more in the future to
Cheers and good luck with your diving progression, we all started off just like you!
Glad James didn't go "Street Fighter" mode on the dolphins with his crowbar when they spooked him.
Good to see a positive end result and glad you have a good group that have each other's backs.
Great narrative throughout the dive. Yes, we can all say you should have done this or that but what you showed is that staying calm makes for a pleasant outcome. Being a long term CC diver myself it’s always good to know that your options are numerous and it’s highly unlikely that any eventuality would require a bolt up to the surface.
Well done.
Cheers - appreciate the feedback!
On a postive note - that wrek is teeming with life! Insane!
All the English Channel wrecks are similar, they're breeding grounds for small fish.
Diving in the UK - loads of life on every hard surface :-)!
Thanks for sharing this - good learning points - and glad it ended well. All under control, good procedures.
Glad it was helpful!
Absolutely fascinating video!! Great description of your mindset and thought process.
Thanks, that is what I hoped to achieve so pleased it worked well for you!
Excellen video - 1000 * Thx! Cool and competent reaction, very good illustration of the insidious mess of some failures. Happy that you are safe.
It is also the curse of a (almost too) well performing ADV. the Us navy mk 15 and 15.5 might be a decent compromise, it has a simple (low performing) schrader valve as ADV which you will notice when it has to be activated. In my (humble) opinion the depth change controlled ADV function on the (very very rare) Interspiro DCSC (now succeed by IS-mix) is the best existing since it will not react to the insidious leak. On the other hand it works best on a semi-closed RB, not a fully closed (-:
/Teknosofen - RB diver since 1989
Thanks for the suggestion although I'm very happy with my unit (AP Inspiration). I think all complex systems have the potential to fail although this certainly wouldn't catch me out again!
Excellent video. Very calmly dealt with. Glad you were ok
Gareth Lock would be proud. Thanks for sharing your experience!

Nicely done! Great explanations as well👍🏻
Thansk and glad you found it interesting 👍🏻
Dude! Well done for skills and keeping calm. Let he who hath sinned not cast the first stone!
Thanks for sharing!😀 Glad you made it out without any issues!
Me too 👍 - glad you enjoyed it
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.
Amazing debrief! I appreciate the great video! 👌
let cool heads prevail!!!! what a great example of this cliché, i cant imagine what would have happened if you panicked, well I can actually, fantastic demonstration of preparedness and redundance and protocol at work as they should be, seen too many of these clips where the outcome was death, well done mate and well narrated, love youe work
Thanks, the great thing about a CCR is you normally have a lot of time to make decisions so no rush!
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!
Thanks for sharing, this was really interesting to watch and throughout you clearly knew you had a bail out if all went pear shaped
@@colinwilliams9290 Thanks and you're right that I had good options open to me at every point in the dive!
As a beginning diver (just got my OW this year, planning to get AOW in the next couple of months), thanks for all the detailed explanation of technical concepts.
My pleasure and I hope it made sense. I tried to make it accessible for non-CCR divers.
A quite brilliant debrief of a dive gone wrong. Personally, had I been your buddy, I’d not let you abort and go for an ascent and not stick with you. I’m not going to stay on the wreck only to learn you’ve suffered some terrible fate. Good on James RedBare for taking over as your buddy and sticking with you to the end, although again, I’d have insisted you get out first given you’d had the problem. Just the way I operate. So pleased you go back and without a lungful of caustic cocktail, as ultimately, the Buddie uses a similar soda lime scrubber, presumably Sonolime or Intersorb?
Another excellent vid, good dive team.
@@Johnx961 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!
Good for you that ended well. Precious educational material, appreciate you shared so we all can learn.
Glad you enjoyed it
Very educational, thanks for sharing. Keep posting :)
@@daveturton1784 Glad you found it useful - thanks 👍
James is suffering bubble blindness, our thoughts and prayers are with him and his family in this difficult time. Not all men can always spot bubbles, for James though, it seems to be an extra struggle, luckily I think there are drugs for this nowadays that give you longer, harder, stronger bubble spotting powers :P
Don't let bubble blindness strike you down lads!
Epic 😂😂
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👌
@@chaingunner60 Thanks, hopefully it will be thought provoking/interesting for other divers!
So amazing lesson learn, thanks for sharing. No judgement at all, good lesson learn
@@deco_cafe_scuba Thanks, hopefully others will use it to inform their own decisions and diving practices!
Thank you for this, very educational.
@@PKNEXUS My pleasure 👍
Thank you for sharing. I have gained valuable knowledge from your content.
Thanks and glad to hear that you found it useful
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 !
They're incredible machines - mine has taken me on some amazing dives and I love it to bits!
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
@@ADJU-A Cheers mate - hope to see you there as well 👍
Glad you made it out ok ❤
Me too - thanks for commenting!
Glad it went well in the end. You say you could have done things differently but at the end of the day. Hindsight is a wonderful thing. Didnt know Toby Tarrant did scuba 😂 you sound just like him.
Absolutely, important to reflect on things on though 👍
Not sure who Toby Tarrant is but I hear that people tell him that he sounds like me😜
Thank you for sharing your story. Good job sorting things out.
Thanks for watching!
It could be good idea (both for owners and producer)to make few small holes in reb cover so in case of gas leakage it can be seen immediately and preventing gas from cumulating under the cover and disrupting bouyancy.
ould do that but this is the sort of occurence that is very unlikely to happen to me ever again. If it does then I'll know how to diagnose it 🤣
Love to dive with such team as you had. Sounds like proper shout out for beer for team guys😅
@@deco_cafe_scuba 🍻🍺🍻
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 .....
Thank you for explanation
Awesome video, thank you for sharing!
My pleasure, glad you enjoyed it
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!
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!
@@nir890 No problems at all, appreciate you watching it and taking the time to comment 👍
Why does James have a crowbar 🤣 great video 👌
@@benfrost1994 Sounds like a question for James ....... he carries all sorts of odd stuff!
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)
Good informative video
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.
Great video....thanks!
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.
Great video! Glad you made it okay.
Cheers!
Tx for sharing.
I've got to be honest I didn't do it when I was actively diving years ago, but I remember from some old school BSAC stuff they used to recomend a "bubble check" at about 6m whilst descending. I wonder if it might be worth reinstating this practice.
I admit that it wasn't part of what I used to do but I did pick up my buddy's open circuit primary bubbling on one occasion. I agree with you if you're changing depth alot spotting your ADV going off is going to be very hard.
I work in medicine and also was involved in retrieval, I'm not a rebreather diver but watching aircrew do checklists made me realise that it's not just about doing the checklist but HOW you do the checklist - doing the checklist as a 2 person check where one person checks and one person does the check - this means that the checklist is definitely completed and both of you will remember doing it or not afterwards.
Just out of interest what was your equivalent air depth when all this was going on?
Only thing I think you could have done a bit better was give a clear hand signal - I have a problem which all divers are going to respond to seriously - then they'd have paid much more attention to the wetnotes and your unit.
I wonder if it would be a good idea to have a line to clip the gass line to the lazy shot which would prevent you becoming separated.
All in all though well managed there's always some things to learn from everything but well done calling the dive and going through it all so well!
Some good points there and thanks for contributing. You can't see the bubble check because it is under the 'how a rebreather works' bit at the beginning.
I'm an ex-Army helicopter pilot and we did 2 person checklists during emergencies. Not really as relevant when you're building a CCR as there is unlikley to be anyone else around when that is happening. Ticking each item off is a way to achieve the same by yourself.
Narcosis is rarely a problem for CCR divers as we can dive high % helium mixtures without really worrying about the cost. I was on 15/60 which has an EAD of 14m/ END of 22m at 68 metres!
On the subject of hand signals, you can't really see them on my video as many of them are out of shot of the helmet mounted camera.
I agreed that clipping the deco cylinders to the lazy shot would have reduced the chance of me getting separated although noting that I abandoned it once I had transferred the 100% mix from the line to my person.
Not dived rebreather (Advanced Open Water PADI) so I found this vid hugely enjoyable and educational. Thanks.
Glad it was helpful!
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’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
Tanks für this Video
It is a good opportunity to learn from the failures of others.
To think other possibilities that can make you a better buddy

Glad you found it interesting/useful!
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!
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!
Great example of proper preparation prevents piss poor performance.
Well done for a good result.
Thanks - nice to know that systems work when you need them!
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.
A small amount of moisture is required to allow the sofnalime to work and breathing also produces quite a lot of moisture so a water detector would register lots of false positives!
@@D33pUKperhaps some kind of float like in a toilet tank that would only be actuated by quite a volume of water. The difficulty would be deciding what orientation to place it in, unless there was one each in the vertical and horizontal directions.
The Scrubber should have a manual water dump valve on an accessible location to purge the water out!
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!
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
As a former professional diver when I was young (so MANY years ago) I should have died twice, and both times I put myself in those bad situations.
Absolutely, Human Factors are easily the most important causes of diving incidents!
HEY DIVETALK JUST UPLOADED A REACTION VIDEO OF YOUR VIDEO HERE! :D
I've just seen - thanks for letting me know!
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.
@ I give the breathing from the side of my mouth on my Xmas dive and I’ll be honest with you I much prefer to vent from my nose. This was from a depth of 40m. Feel like I had more control with it out of my nose.
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?
That amazingly ungraceful entrance into the water actually loosened one of my front teeth!
Excellen video - Thx! The curse of a (almost too) well performing ADV. the Us navy mk 15 and 15.5 might be a decent compromise, it has a simple (low performing) schrader valve as ADV which you will notice when it has to be activated.
