- Correct video this time! Apologies to everyone who watched the corporate video I uploaded last time...this one will be of much greater interest!
The 2020 Pearse Resurgence push dive to 245m required a large team to help install 4 decompression habitats, heating cables, communications and CO2 scrubbers. This light hearted video looks at the process...
That's amazing I always wanted to see what it looked like in those habitats, thank you so much this video was very informative. Mahalo
Glad you enjoyed it!
I've been a commercial diver for 12 years and never knew this was a thing! You guys seems like a good time haha dive safe
How would you know not know that???
@@thirstybonsai1888 no doubt he knows... OP was referring to the diy nature
I love your sense of humor. Amazing what kind of effort you put in for diving so deep and very interesting how long the decompression time actually is. So cool and a totally different way of diving 😎 😀
Watched you on dive talk and you were fantastic. What you did for those trapped Thai kids was simply amazing. 🙏
After the Tham Luang cave rescue mission, there is no need to introduce yourself and Craig to the world...sort of.
I m not into all these risks taking adventure but surely enjoy the beauty. Thank you for allowing people like me to appreciate your exploration.

Wow that is awesome! Those habitats are such a good idea, I was imagining you were doing 16 hours deco in the water, this looks way more comfortable..
That is passion, taking body to the limit, in a “safe” way but a little mistake cost life. How much i love this.
Just watched a Jimmy Carr special …. Then happily stumbled across this masterpiece! This was way more entertaining ! So good to see Craig chatting . Have read your book, seen both docos/ Movie ( wished Craig was featured in 13 Lives ) , and been to Tham Luang about 6 months after the rescue . Awesome to see couple of Aussie legends having fun 😂😂🇦🇺🙏👌☝️
You and Craig have so much personality. You two were fun to listen to
Jeez, never seen anything like this! Insane! ... I thought sitting under an umbrella staring at a fishing float for 24 hours was an extreme way to get away from the wife !
Great habichat! Looking forward to more of them. And you, Craig and the rest of the Mules have an open invitation to come and try out ours any time!
Thanks Andy, I'll be coming one day!
I just finished your book so I came looking for the cave that you described in the book. I can see why you both enjoy cave diving so much. It looks so peaceful especially with the fact that it isn't the type of thing that draws a lot of people in so it would never be crowded like some of the hiking tracks in that area do. It also made me wonder if that cave was caused through glacial movement as well. Especially when you consider the area and the fact that it is the South Island as opposed to the North which has all the volcanoes on it. The south tends to specialise in the glaciers
If you are interested in how the caves form in that area, read this article: www.tandfonline.com/doi/abs/10.1080/03036758.1982.10419437
Great video that enlighten us on this
matter. And you both are so funny!! Thanks a lot lads
Oh, !!! You're sitting in water. I just saw that! You guts always heros!
Mann this is awesome I just discovered your channel from Dive Talk. Thank you for sharing your experiences.
Wtf a 16 hour dive?! This is unreal, you men are a lot braver than me, glad you guys keep each other entertained. Safe diving! 🤿
Wait, Craig can smile ? 🤣 - Great to meet him at the Exmouth cave rescue exercise.
New subscriber here. I see that it won't take very long to get through the uploads since there was about a decade long gap in them. Lol. I hope that you will be uploading many more.
Stay safe gentlemen. I know that in most things there are acceptable risks associated with them, but we need our explorers, risk takers, and those that move the technological boundaries forward to be able to continue to work together.
Be well and keep up the good work.
You guys are a hoot!! Thank you for sharing. 🤗
Our pleasure!
You guys are incredible, crazy as hell but incredible, the depths you are at and boundary pushing is amazing. Great to see how it goes for you guys.
Thats either amazing or completely bonkers. Havent made up my mind.
Thanks for sharing
I am binge watching your videos and the pearse resurgence story. I don't do anything even remotely like this, but it's so interesting to me.
It is incredible all you let us know, things that we just can dream of. Thank you both Doctors for Being so special
What a fantastic video. I've been following your adventures for years, first just the maps but now the video. Keep the content coming!
you guys are a blast cheers mates, always stay safe!!
How to entertain yourself during extended deco stops. 😂😂😂. This was amazing
Are those habitats left in the water permanently or set up for each dive? Seems like it would be a massive job just in its self. love all the content by they way, always looking forward to new vids
No we clean out the cave after each trip. It takes 5-7 days to set up the cave every year and then usually do another few days of build up dives before the exploration dive.
@@DrHarryH that's some serious dedication
@@DrHarryH how do you get the air pockets into the habitat like that??
@@johndreyer9730 fill them up from SCUBA tanks until the pressure inside ,equals the surrounding water pressure. Hence we can sit inside them and be at the same pressure for our decompression.
Are you able to do multiple dives likes this back to back or do you need to wait months or years to tackle it again?
This has to be the coolest video i have ever seen. Gonna need to build a habitat now. How cool is that.
So glad you posted this video. I’ve always wondered what the habitats were like on the inside. I never thought I would get the chance to see, so thank you.
Didn't know Clark and Dawe even dived
You guys are delightful.
This feels a lot like the golden age of mountain climbing
Based on your sales pitch, it looks like a great place to stay.
But, I can't find it on Book a Bach!!
Regards Paul in NZ
You have to look in the - 5 star listings.
I just heard Craig on Dive Talk say you guys might be going back in February 23. That will be awesome!
You mean Harry , font you?? Harry was on dive talk talking about that.
Where is the coffee maker? Hot soup and chocolate is nice but there is no need to rough it chaps. 🤣
Holy Shit you guys are the heroes of Tham Luang ! I just finished the book !
What book? 👍
I like to imagine that making this video was the only thing keeping you guys sane during a 10hr+ deco
truly amazing, you all are rockstars, and super heros. all the respect mates!
Funny, my 1st comment was asking you to do this video then I found this, thanks for including us!
Super interesting to see how this works. Thanks for sharing!
Love bringing the cap down here.
G’Day Harry, great work on the Habichat… Fine example of the incredible teamwork that goes on in the Cave Diving Community. I have two queries for your consideration.
1/ What is the ratio of support people to one dive team per dive? I suspect that you stay in the camp there for several days support other divers and wait for your turn to dive that way everyone who can get a dive to their level of experience.
2/ Is spending 16hrs TDT with Craig Chalmers in the New Zealand Pearce Resurgence affecting your Australian accent?? I unfortunately noticed a possible New Zealand lilt to both your voices and my mind went to worst case scenario that you might have an allegiance to those horrid All Blacks..
Best wishes to you all.
Tone
Me and my wife are watching this video wondering, if the habitat some how got a punture in it if it would implode👀
It wouldn't implode, it would just leak and we'd have to refill it which is easy. If it suddenly broke loose or split right open, it would indeed be a very bad day :-(
@@DrHarryH thank you, i honestly didnt know
Hilarious and so incredibly fascinating, thanks for sharing this video!! And who would have thought cave divers were so social and chatty when down so deep😂
any transparent material durable enough for a better deco stop view instead of orange?
Absolutely fascinating, this is real exploring. Thanks for sharing!
I cant help picturing a fish stumbling upon a floating orange ball that seemed to be talking to itself.
Another cracking video 😆👍. Good to see the 03 suits - local to me. Keep the content coming.
Thanks, wouldn't dive cold water with anything else! 👍
Thanks for uploading Richard! (will watch it tonight after dinner but was keen to say thank you early on :)
that was a great watch! thanks so much for uploading. You guys are incredible.
Wait... why does the inside look 5X bigger than the outside? 😂🤣 There's like some diver magic going on!
By the way what you guys are doing in Pearce is amazing work, thats a DEEEEP cave and you just have to wonder how far it goes. Can't wait to see what you find next!
“Thanks dude….” Funny bastards. Great episode.
Great video. Really interesting and informative 👍
I'd totally watch livestreams of ur dives, you can talk to chat while stuck in decomp
You mentioned in another comment about the effects of oxygen toxicity on your lungs for your bottom mix. I assume you guys are running razor thin margins in PO2 on bottom for decompression reduction reasons but what is the physiology of how the toxicity is damaging your lunch? I thought the only real risk of high PO2 was convulsions. Would be fantastic if you had any public research on the matter!
Hi Adam, we don't push the PO2 too high especially during the deep parts of the dive for a couple of reasons. Firstly the PO2 at depth doesn't affect deco times nearly as much as it does in the shallows, due to the lower fractional content that the oxygen represents of the total breathing gas. Secondly, high density at depth increases the risk of CO2 retention which is a risk factor for CNS oxygen toxicity (seizures). In terms of the lungs, (OTUS, UPTDs) it is unlikely to cause permanent damage but it certainly produces symptoms which can take hours to days to go away. And this transient lung damage might theoretically impact the efficiency of the lung's ability to clear the inert gas. Have a look at this and other recent articles: gue.com/blog/pulmonary-oxygen-toxicity-expanding-our-understanding-with-two-new-models/
They leave out the part that explains how they are able to dive so deep. Their balls are actually made of solid steel which allows them to submerge so deep.
Woah!!! I'm very curious what the outside of that looks like! Are you able to sit in there? &Thank you for sharing this! After watching the video of the dive through the cave, I had to know what a habitat was for! I'm a novice SCUBA diver (60 dives), but hope to one day (after a LOT of training) be as cool as you guys. Thanks for the video! 😁
Were the first few "habitats" filled with water? That was surprising to see. Seems uncomfortable to have to wait for hours like that
No, they are full of air or nitrox.
Recommending you both for the first manned Mars expedition. That guy leaning looks like Mike Rowe btw.
More of this sort of stuff please.. fascinating
Two questions:
1) can you talk about how you ‘go to the bathroom’ during the long deco stops? I know about drysuit P-Valves, but would think voiding while suspended in the same water in the lower habitats would not be polite, and it doesn’t answer the second void problem. Adult diapers like the astronauts wear maybe?
2) was muellermatic-like device ever considered during the Thai cave rescue?
Good questions! Yes the P-Valve answers the first issue and well frankly, you get to know each other pretty well for 16hours in the water together! You can drop int the water a bit for a wee or just wave it away! Regarding the 'other', the Fourth Rule of the Wet Mules states "if you shit in your suit, you are off the team". We find this rule highly motivating to avoid such incidents. The Mule - O - Matic 5500 was far too advanced for the cave rescue. Actually CO2 was never an issue in Tham Luang. Other Rules of the Wet Mules include Rule 1 - Have fun, and Rule 2 - Don't kill Ken.
Sherwin glad you asked because I was wondering the same thing. And this answered my question about eating and drinking while diving.
@@DrHarryH Non diver here. So I just googled a P Valve. It’s basically an external catheter? What do the women do? Do they make a valve for them? Being a woman I would love to learn.
@@DrHarryH Also who is Ken and why does he inspire such homicidal rage?
@@rustyshackleford4822 Google She-P and Shewee. Then prepare wax, razors and glue. That's all I know sorry!
The pressurised atmosphere has given them comedy accents.
You guys should start a fundraizor and maybe get enough funds to built a habitat in which you can bbq...you guys deserve a nice meal after such a dive.
I'd love to know how the Triton rebreathers are. I love thier small size but have no experience with one. How do you like them and do they work well as a main rebreather? Thanks
Hi I have dived mine as a stand alone unit quite a few times. I especially enjoyed it diving wrecks in Truk Lagoon in the warm water. The French manufacturers have done some major cave dives on them I believe. Not sure I would do that!
Incredible video!
Many thanks for sharing all of this. I did a handful of recreational dives many years ago. Your videos about this particular exploration dive, as well as the Dive Talk reaction and interview, have been a fascinating introduction to the technical side of the sport. You mention at around the 2:25 mark that you have an earlier video filmed in the 16m habitat. Does that live online anywhere at the moment? If not, any chance we could convince you to add it your channel here?
You guys kill me!! LOL. I hope you stay friends .....
Simon sounds a lot like the adults on any of the Charlie Brown cartoons!!!
This is like listening to a Martin / Molloy skit, if Mick Molloy were replaced by a second Tony Martin, and both Tonys Martin suddenly developed a strong fondness for cave diving.
I take this as a great compliment!
@@DrHarryH It's very much intended as one, I could listen to the two of you riffing for hours! I hope you do more of these habichats in the future, and I can't wait to see your next excursion through the Pearse.
Amazing! Thanks for this!
I imagine you could come across gold veins or untouched alluvial deposits.
You really know your stuff!
You're incredible
Harry, I've watched this video about 8 times now. The more I learn about diving, the more things I find in the video. Cheers to Craig! A question. That is rather a deep dive. I know you said some trembling. What else at those depths in the Pearse make it so challenging? How will it affect future exploration?
Questions from a baby (50m) technical diver:
Can you sleep?
If a safety diver (or your buddy) monitors PO2s, it's theoretically safe, right? Probably not the most comfortable thing in the world, but at that point, you're basically in a cutrate Aquarius Reef Base...
Also... What's the plan if the Pearse gets into the 300m range? Hydrogen, neon, or submersibles?
Considering passage size and logistics, a tiny submersible is starting to seem more practical-and probably similar in cost!
Apart from the cold, the sore bum and back, and the precarious balance on the timber seat, I reckon I could have a bit of a nap!
@@DrHarryH sounds like some bigger habitats and hammocks are in order!
Or, perhaps a pair of Newtsuits, courtesy of book proceeds?
(Nice work, by the way 🐗)
All you need now is a 12 volt Bar fridge, tv/dvd player and a toaster oven....
I cannot imagine having to do 15 1/2 hours of deco.
hey i was wondering if there is actually a difference in the time needed for decompressing in the ocean or in a cave, i feel like a cave would actually need less time since the limited amount of water filling in the cave.?
No it's all the same unfortunately! Pressure is pressure, no matter what the type of liquid that is generating it. The only factor that can change things is with a dive performed at altitude due to the lower atmospheric pressure.
@@DrHarryH Are there any caves at a high altitude that people cave dive??
You guys are awesome legends.
How do you ballast your habitat? There would be a lot of buoyancy to counter-act.
Hi, I have just discovered your channel and I am loving it !
I've been wondering, how do you keep those habitats from floating up ? (Do you bring down weights ?)
We use climbing bolts into the marble to tie them down.
@@DrHarryH Oh I see, thx, and good luck with the exploration
@@DrHarryH how du you drill those? underwater?
@@ichDAINVADDA Pneumatic drills
What's that mule-o-matic thing for? Haha
Carbon dioxide elimiination
Cant wait for part 2 hehe
Nice habitat, did you book it on air BnB or Agoda?
Amazing content
Awesome videos!!! 😍
Alot of info here, love it
wow this is great, thanks for the vid!
Does the cold temperature add to the deco time. Next year I would like to see a live podcast wired headsets are so last season
Awesome, thanks for posting
Hi, how do you monitor the air mixture in the habitat? How do you know when the Gas in the habitat is consumed? And change the air? Thanks
Part of the scrubber setup has a couple of oxygen sensors and a display built in. The O2 declines very slowly. We top up the oxygen from a cylinder by simply cracking the valve intermittently. Simple, but effective.
Glorious!
Warm hands, warm hearth is so true 😁
What decompression algorithm do you use for these dives? Bühlmann + GF?
Yes, and have very gradually been increasing the lower GF over the years to get out of the deep water as fast as possible.
@@DrHarryH What is your GF now? I don't dive that deep and use 50/70 for 100m dives in 8 degrees water.
Just brilliant!!😂
Please send your video links to the guys at Dive Talk
Be my guest!
Would it not be easier to send a small remote submarine down the cave? It's big enough to do that and you can expore and map the cave easier that way.
i thought of this, safer and all also, however where is the fun in this. maybe if the cave system gets too narrow they would send a remote sub. but this is exploration the old way. and its awsome to see it. but yes some do the remote viewing. but again the camera is never like the eyes!!
there arent a whole lot of remote submersibles, if any I think, that can operate in the confines of a cave, signal through rock is not as easy as open water remote control. Bill Stone made one that mapped El Zacaton but that is just a vertical shaft underwater
That's a great idea. soon as you invent a signal that can pass through hundreds or perhaps thousands of feet of rocks.
@@danielgarrett7226 you just need an electrical cable...
@@infectionsman an electrical cable underwater!? you're asking for nuclear fission!
Non diver here and I'm so confused! What if something goes wrong such as the habitat starts to tilt or gets a leak? Doesn't look like they are ready to suit back up in all their equipment. Also, are they in that white thing with a wire cage we saw them taking down? It looked smaller than this?
Yes, the same white things. They are very small inside and our faces are almost touching. We have over engineered the restraints holding the habitats because if they suddenly failed, we'd be dead. A slow failure can be dealt with as we have several backups close to hand.
@@DrHarryH Thank you!
what are you breathing on deko inside the habitat?
In the 16m and 7m habitat, we breath the habitat atmosphere itself. We have a fan forced CO2 scrubber in there, and bleed oxygen intermittently into the 'room' to maintain a PO2 of about 1.3. We have cells and a dive computer in there to monitor this. The PO2 changes very slowly due to the volume of gas in there, so it works very well.
I couldn't think of anything worse to do
Good dry suit choice
I am a massive fan of O'Three suits, warm and dry! And great people to deal with.
