Divers React to 800+ ft deep dive by Dr. Richard Harris at Pearse Resurgence 

Hey guys, thanks for having me on the show. Love your content and hope we get to dive together one day soon. Harry

This is one of the most incredible videos I've ever seen. Good on you guys. The combination of technical and emotional is just unparalleled. Amazing work and interviewing.

I’ll start by saying that I’m a diver but not a cave diver. While Richard is obviously a legend, my first thought on this video is that I lost count of the reasons why I, personally, would have thumbed this dive. It also sounds like Richard feels this way too. Craig appeared to be having some buoyancy issues and, from my perspective, some questionable judgement issues. If I was going to depths such as this, I would need to know that my partner is good to go. It’s still a great video and I’m excited that you guys reacted to it. Having Richard on to discuss this dive and the rescue was epic. I knew it would make a good reaction video when I watched it a few weeks ago.

I've got a pretty high tolerance for risk in the name of exploration but the thought of being 800ft underwater in a cave sends shivers down my spine. Mad respect to the divers and the teams that make such amazing feats possible

That tie-off made my heart skip a beat and I don't even swim.

You guys are good... I'm not even a diver and I was asking the same questions about gas mix and deco time just from watching your videos lol

Just to think that cave has been in darkness for thousands of years and then these guys just come floating through thousands of years later

imagine coming out of a khole underwater with someone dragging you though a cave lmao

To be able to talk at the same time too, at that depth. Incredible

Such an amazing interview and video thanks for sharing this with us y'all are at the top of the game in the dive world

I have a question, would a mix of hydrogen and oxygen instead of nitrox ever be feasible for recreational deep dives? I was wondering if it would be dangerous because of the explosive possibility of the gas mix, or if it would be possibly mitigated enough because it’s underwater. I guess it wouldn’t be rational to use in the setting of tech diving like when people are welding, but perhaps for these kind of super deep dives? Sorry if that’s an incredibly stupid question, I’m not a diver - YET lol.

16 hours underwater??!!!!??!?!?? For real?!!? Omg 😮

You never separate stupid move , don't do it.I also looked at the re-breather set up and check list some 30 point to check all the equipment ,seals,valves % o2 etc.wow just so much breathing in from the right ,exhailing from the left.Wow mind boggling well done on the children cave rescue really fantastic.The Bushmans Hole in South Africa comes to mind when going on a deep vertical dive and how sad that rescue dive turned out for the New Zealand diver.

Christ these guys are top notch elites no panic what so ever

I'm amazed the human body can handle that, even with all the technical gas mixes etc.

You’d think down that deep that there would be gold in the caves

Dr. Harris' dive skills are eclipsed only by his humility. When I was in medical school, a very wise professor taught me "There are only two kinds of doctors - those who are humble and those who are about to be." I aspire to be just like Richard Harris. This dude is such a fantastic role model. Respect ✊

I’ll never get over how lucky those kids were that one of the best cave divers in the world also happened to be a practicing anesthesiologist.

I think the sweetest moment of that cave rescue though not mentioned was when the kids decided on who would be swam out first based on how far they lived from the cave because they thought they would have to cycle home. 😊 Epic story of human endeavour for sake of human life that for a brief moment bought humanity together..

As a non diver, I watch every video Woody and Gus make, why? not only are they both great story tellers, but the quality of the videos are fantastic and this makes for an enjoyable experience. But, mainly, I am learning about how exciting and educational diving can be and, even more important, the lessons of safety, which is the main purpose of their videos, apply to everyday life for non divers. So these videos teach you to be an expert in your trade, use your head, use common sense.

No wonder this guy was Australian person of the year! He’s got that humility you see in so many Australians, never taking credit for the awesome things he’s done. I have to say, this was one of the best videos I’ve seen, (other than any video with Edd)😃 Thank you so much!

52:34 " What are you going to do? You have to just get on with it." He thought there was practically no chance the rescue would be successful, and was warned he might be imprisoned if anyone dies, but still never hesitated. I couldn't have more respect for him.

After seeing how quickly David Shaw went from "doing work" to being dead at 900ish ft. (30 seconds, if that), I have a lot more respect and a deep sense of worry for anyone else trying it. Its so deceptively dangerous. That being said, what a beautiful cave. My God the story of that rescue though, wow. That is insane.

Man, those are some CRAZY depths!

As an Aussie, this fills me with so much pride. What a guy. Very proud to see one of our own out here doing fantastic things. I also have to say, it's nice to hear a familiar accent 😂 Edit: No way, he's in my neck of the woods too. Super awesome.

Thanks you guys. Thank you to Dr. Harris for guest starring. Thanks for doing this and doing it for the right reasons. Amazing content always and quality human beings.

I know this gets thrown around a lot but... This man is a hero in every sense of the term. He and his crew literally risked their lives to save these kids. I'm not expert but it almost seems like rescuing someone from outer space would of been easier than what they did. I was glued to this video. What an amazing story and individual.

Damn this guy rocks lol. I've seen local musicians with 100000× the sense of self importance Richard has. It's a blessing to have you and people like you here on earth with us!

Being an anesthesiologist helps him massively understand dynamics of deep diving. Incredible human. Great video guys!

I love how he talks about his emotional state too, not just the process. It’s wild all of the places we don’t even know about on the earth. These guys are amazing! Places that most anyone will NEVER see in person, they showed to us. Dry discovery is amazing as it. There is so much under the water that we have yet to see. Wild.

I subscribed to Richard Harris at about the “argument” point in this video. He was so deadpan with his delivery and hilarious. Very calming when watching something that is so advanced and dangerous. Simply incredible.

I’m a medical student in Australia and we are all in such awe of Dr Harris! I hope we get a lecture from him someday.

Another incredible interview of a Legend! Somehow your content keeps getting better and better! Thank you Gus and Woody yet again 😎

I've never been more glued to a discussion like this. Harry has the attitude, morality, and modesty that is so uncommon in today's society. A true hero we can ALL APPLAUD and learn life lessons from. Great show guys.

I think a guy like this is FAR greater than those that attempt Mt Everest. Not that Everest is a small feat but very few men have the balls, physiology and knowledge to dive to these depths. Insane!

As someone who is terrified of drowning and being underwater for extended periods of time, the two of you have made me consider taking a diving class and trying it out someday. Stumbled upon one of your videos and now I have to keep watching, very enjoyable thank you!

Wow! This has got to be one of your best videos to date. The dive footage was epic and the interview with Richard Harris was just so engaging. Great work.

I am hooked on your Dive Talk channel, and currently binge watching! I was scared off with Mr.Ballen's stories of ever doing any open water/cave diving, but after watching you guys talk about how it can be done safely with the right precautions and equipment, and how beautiful and breathtaking it can be, it sounds like something Id like to get certified in one day. I love how you both compliment each other so well Woody and Gus, and the upmost respect you have when talking about the unfortunate things that can happen in your profession, but turn them into learning points on how to safely do something, or why it went wrong, or how to avoid it in the first place. Not to forget I enjoy all the collaborations you do too! KEEP UP THE GREAT CONTENT GUYS! :)

Thank you for not only risking your life but your freedom as well to save the kids.

What a great interview!! Getting to see the cave at those extreme depths all while listening to Harry narrate the adventure - wow! Hope to see/hear more from him. Definitely will be subscribing to his channel. Thanks Woody & Gus for another stellar discussion! So good!

What a legendary diver! Being able to see video that deep into a cave is amazing, the overall video is truly beyond words. Keep up the amazing work

That is extremely terrifying and absolutely amazing, these guys are definitely a very rare breed.

I also forgot to mention so Apologies ahead of time, but I really enjoyed the conversation about the logistics of gas and deco. Three weeks plus 4 tons of gear is so insane it is hard to physically imagine.

This has to be one of the most amazing videos I've ever seen. Makes me proud to be Australian. I'm sure he was my anesthesiologist while in surgery. He's a legend.

Gus and Woody's videos are the only ocean underwater videos I can tolerate without getting anxious. I love Gus's smooth accent, and I love how unique Woody is. His personality and the way the videos are put together are great. This guy is AMAZING! There aren't words to describe this. I won't even get in if I can't see the bottom. This is spectacular and informative

Staggering,total respect for all involved in that rescue.

This was an amazing video. It was an even bigger surprise at how instrumental he was in the Thai cave rescue. Thanks to you guys and Richard for all the great insight into everything: the logistics, the effort for safety, the extra info about the Thai cave rescue, and just being awesome!

The whole ridiculous decompression I feel like probably keeps a lot of people from diving this deep especially cave diving. It would be cool and I'm sure some like the challenge but the extra risks plus from what you guys say like 12 hours plus of deco would negate a lot of the enjoyment you gain I'd have to imagine. not a diver but I know it would for me. Plus you could explore tons of Caves that aren't that deep and don't come with all the same things deep Caves do.

I love how they have an argument at 600ft. Deep 😂 the most hardcore argument ever.

As a 70-year old woman who tried hard to learn to scuba while in my fifties, I am in awe of all of you. The doctor would not certify me to dive in Australia since I had had breast radiation for cancer. I was disappointed but it beats having my lung fail underwater. Now I watch you guys! Fantastic having Dr. Harris on. He's my hero. Every video makes me cry...

If you haven't already seen it, one of Harries friends/compatriots (I think Craig) uploaded an incredible discussion of their most recent expedition. Harry did an even deeper dive with a hydrogen mix of gas. The theoretical benefits of using hydrogen in a dive mix have been known for a long time but I'm pretty sure Harry was the first person to ever test it. They used an even lower %of oxygen and a small amount of hydrogen to reduce the risk of explosion. It was an astounding success but Harry and the team absolutely do not endorse anyone else try it lol. Hard to imagine anyone else being upto the challenge of that cave rescue. Of course it was a huge team effort comprised of many elite divers and it's great that Harry highlighted that but I doubt there are many elite cave divers that are also medical specialists in anaesthesia. It's amazing that the world even has one elite cave diver who is also an anaesthetist.

Just. WOW. I could watch him talk all day. That dive was amazing and of course his work with the Thai rescue is incredible. If you guys don't get him to Florida to dive with you AND go to Australia to dive with him you'll kick yourselves later. Thank you for sharing and thank you to Harry for joining the DiveTalk family. GREAT video!

Excellent reaction and interview. I cannot thank you enough for reaching out to Richard and getting him on here. I would say that I will head over and subscribe to his channel, but I am already a subscriber. Thank you all for giving us glimpses into things that we will never experience for ourselves and would otherwise never see it or hear about it straight from those of you that are/were there.

I have a question, if you guys are out diving in a cave and you see non cave divers/free divers in the cave do you try and stop them or signal to them to leave? In other words who enforces the rules of diving?

If Eagle's Nest is Mt Everest, this place is the moon 😥

So what's next, Xavier Meniscus at Font Estramar? 😜

Man , i'm not a diver, but that tie-off @ 10:53 ! omg , I really don't think i would be confident in that holding, But what do i know ?

The thai cave rescue documentary was amazing and brought tears to my eyes. It truly showed what humanity is capable of when we come together. People from all over the world and all walks of life left all of their problems and politics at home and worked together to solve an impossible task. It was a true testament of what the human race is capable of and saddens me when there are so many problems we can solve if we came together like this cave rescue.

I often think that cave divers are completely mad for doing what they do - but then one day a bunch of kids need rescuing from a cave, and thank God!

What a down to earth, lovely and humble man. Keep watching your own videos back, learn from your mistakes, stay alive. You seem to be one of those people that will teach hundreds of others how to be safe in their cave diving careers. You need to brag a little more. You are amazing.

Noob question: is there a point where your tissue is fully saturated and you hit a roof on your deco? I mean.. how much more deco would they get if they just spent a few hours exploring new cave instead of only a few meters? Sure maybe they'd need a more comfortable habitat and a way to warm themselves.. but it seems so pointless to invest that much effort, time and money into only exploring a few meters of new cave, right?

Hey Woody and Gus my name is Josie, I’ve been watching you guys for only a few months now but I’ve been binge watching all your videos ❤️ but I think I have a great idea, they make waterproof playing cards. Maybe on long deco times you could play card games lol. I’m no diver I’m barely a beginner at snorkeling off the beach of Anna Maria, Fl close to where I live. But maybe even a funny video idea to gather everyone together on a shorter dive and just playing card games. I think it would be hilarious watching y’all play slap jacks under water 😂.

It’s cool to see a cave from my neck of the woods. There are so many caves in the top of NZs South Island. It’s really nice to be able to see inside one.

I don't understand how it's humanly possible to do a 16-hour dive. Do you sit in a habitat for 12 hours? Do you eat? Do you drink water? I guess you put yourself into a state where you don't need to use the bathroom either? Absolutely mind-blowing stuff

Great story! Loved the Q&A, you covered all my questions. Do you realize a trident submarine has a max depth of like 1300ft, these guys are pushing that envelope... Sheeeeezzz

Fantastic perspective from a fantastic diver! It's stories from people like this that truly give me the nudge as it were to explore getting into diving. Also can't wait to see episode 2 of Woody's adventures at the aligator farm!

Hydrogen is used on deep dives not nitrogen. Comex sent divers to 1700ft using 49.2 percent hydrogen 50 percent helium and .8 percent oxygen. The problem is hydrogen becomes narcotic around 1600 ft. In hydra 10 they brought a diver to 2300 ft in a chamber unfortunately the hydrogen narcosis at 2300 feet makes getting any work done almost impossible. But they proved that divers can work at 1700 feet with good motor skills for a full 28 day shift 17 days 11 hours of that was decompression.

Dr. Harry showing up in the middle of this to share his own experiences with yall!? Absolutely wicked!!!! Thanks so much you guys :D

Its amazing. Just a decade plus back these depths killed Exley and Dave Shaw, and they were literally just doing a bounce. Going to depth and then going back up. Dr Harris and his partner are going to depths and staying for some time period. Mind blowing.

Is 800ft deep in a cave the same as being 800ft in open water in terms of pressure? Because the column of water isn't directly above you. Probably a basic science question.

By far some of the coolest content I've seen on RU-vid such an amazing story could listen to you guys talk all day appreciate the content and always surprising us with guests appearances great video also want to say thank you very much to Harry

RU-vid brought me to your channel for some reason. I've now watched a few videos and have a sudden growing interest in trying diving. It looks so peaceful. Beautiful.

As someone who has always been interested in diving… but never gone… I absolutely LOVE your channel. I may not understand a lot of the info, but it’s fascinating! Thank you for letting me tag along on these fabulous adventures.

I'm not a diver, so this is probably going to be a really silly question, but how do you manage human waste on a 16 hour dive? I'm assuming the underwater habitats don't have a toilet, and the dry suits don't appear to have enough space for absorbency garments. The reason I ask is because I'm a colon cancer survivor and I have to plan everything around bathroom accessibility.

Seems pretty dangerous to have that big mess of line just hanging in the cave

Have you guys ever just turned off your lights in a cave just to experience the blackest of pitch blacks? That level of darkness must be a pretty amazing experience...

Harry is a remarkably humble guy. Much respect.

OMG this is the best show ever. The amazing depths, new cave tunnel then about the rescue of the children. I had no idea, just amazing. I woke up my old man to tell him All about this video. Thank you so very much. I hope you guys get your wish to dive together. You guys take me where I could never go.

31:00 I love how he didn't push himself to go through this narrow corridor. Reasonable choice. I really respect that

Cool to see the rounded basalt at the beginning compared to more recently fallen stuff at 17

This was the most amazing video/interview I have ever seen… Dr. Harris (&Rick) really came through for those kids; I remember watching the rescue, eyes glued to my TV. The Docu on this rescue I’ve watched twice. Words cannot express the feeling of love for humanity that bubbled up when each child was brought out. ❤❤

I Respect you guys tremendously for your skills Diving and on U Tube.

Lol "that pain takes a long while to wear off". That's how I felt my first back country skiing experience.

I dont want to Sound like an asshole, but this is just endless dark Tunnels of cold, dark rocks. There is nothing to find down there, but more rocks.... I somehow dont get it. Whats So facinating?

Came across Richards channel a few months ago. I was completely awestruck the first time I saw this video. Had no idea anything like this was possible! Great to hear your guys' reaction to it and help put some things into perspective for us

In 2017 itry to dive to see titanic but when i reach 800 ft ithink i cannot reach and i go back and never try again😢

They say cave divers are crazy but listening to you guys talk, I couldn’t imagine a more levelheaded bunch of people. Loved this talk, keep up the great work!

16hrs !!!! Holy cow that’s a long way back up

Wow, just wow.. I'm a 20 yr reg nurse, and avid diver.. what they did with those kids is mind blowing... Zero vis, have reinject to keep sadated...through crevasses..just wow...awesome video guys, thank you!!!!!!!!

Gonna pass on Disney but you should do a divers react to that feature. I’ll watch that.

Kinda random but I had one shitty day at work today and mentally I'm pretty down right now so when I seen gus and woody uploaded a new video It legit lifted my mood instantly! Thank you guys! Seriously, it's much appreciated.

I bet it would be cool to dive to the bottom of Lake Superior over 1,000’ deep if it’s even possible.

The documentary about these dudes at the Thailand rescue operation is insanely good. Rick Stanton and John Volanthen are such cool dudes... they all are (I think it was mainly about them and also Richard Harris in the documentary). Crazy how insanely calm they are even during the worst situations possible for divers (I'm talking about the rescue op). They said that exactly this kind of hobby (what you can see in this video... like "extreme cave diving") prepared them for that, but for them it's like pure joy and relaxation. But every one of the divers who carried a kid through all that caves is a heroe, imho. To the rebreathers: I knew that Rick Stanton is creating his own equipment in general, so all that gear talk was awesome as hell,especially about the rebreathers! Would love to hear even more about the gear... gear-talk is always the best talk. :D

so is hydrostatic pressure exclusively based on deapth? and not volume? I always assumed having the whole weight of the ocean weighing upon you would be stronger

Amazing interview, to say the least! People involved in this caliber of rescue are admirable beyond words and come with the biggest hearts.

Fun math. 815 feet of fresh water is about 24 ata? Assuming a surface air consumption rate of 0.75 cubic feet per minute, an aluminum 80 would only last about 4 1/2 minutes at that depth? Please correct me if im wrong.

What a honor having this man in the show, amazing content guys, and Thanks Dr. Harris

at this point, so much deco, i'd just want a chamber on the surface and do the whole deco there, like commercial divers do...

I’m listening to this and I’ve been amazed every time this Dr talks about this rescue. He had to teach the other divers to keep them out. It’s just amazing. .

This is a curiosity thing - would divers ever be able to take down tanks ahead of time as a back-up kind of thing and place them around the cave?
