245m Cave Dive in the Pearse Resurgence, New Zealand

Ever think of how much bonding you would do while sharing that 40 min experience and HAVING to slowly contemplate it on your way back? It would be extremely visceral and maybe you'll have a clue as to why many of these divers have the relationships they do. I imagine if more people recognize the significance life and the world would be VERY different. Too many take things for granted.

I just wish they kept going whichever way was because even watching from here is mesmerizing but I’m sure safety is first.

I can't fathom the feeling of being so isolated and deep down in a hole filled with water in which one mistake can literally kill you, and there is no help. this is bravery on another level.

Bravery or mitigating risks?

[@intrepidsouls]

@@byteme9718it takes guts to do that. Or lack of brain matter, but those don’t survive.

[@byteme9718]

@@intrepidsouls You can drown in just a few metres of water outside of a cave, I saw one diver fatality in just eight metres of water with perfect visibility in bright daylight some years back. I think if you were to ask him whether it takes guts, the answer would likely be no. It does however rely on practice, planning, equipment including redundancies and contingencies. If he considered the risk levels were high he wouldn't do it and that's why just a few people like him can do what they do. The hazards are there regardless but these are planned in to mitigate the risk to near zero. You're 100% right that those with a lack of brain matter get themselves in trouble. I've been diving for a long time and neither extreme depth or caves hold any interest to me but we're all different.

@Someguy Something These guys have been in that cave numerous times already too. To me its wild to think that they are doing this re-breathers. Most re-breathers are only certified for recreational to minor deep depths like 80-160ft because the pressure could cause them to fail. I know they designed their own custom riggs for this but its still gnarly. Probably also the only way they could do this dive, since pressurized gas would be used far too quickly at those depths and would need dozens of tanks.

[@TheMarcoflint]

I honestly have a real trouble to understand how so insanely trained cave divers manage to do so many elementary basic mistakes of cave diving... To a point that watching this video is just stressful... - Buoyancy control is inexistant fins are banging all over the place. And even if in a high flow cave it's less of a concern... How about conservation ? - Diver #2 passing in front of diver #1, in addition to flood light on DPV (reducing ability to communicate with primary lights) which lead to team separation (it's already bad on an easy cave dive... But gosh that dive is fairly extreme...) - You guys get near entangled multiple times - Diver #1 deploys a reel with absolutely no tie offs... It's floating and turning around... The line would just be useless in case you need to follow it by touch contact ... - What happens to "keep a continuous guideline to exit"? ------ I understand sometimes rules can be bent to adapt to the environment... But come on... What kind of example does it set? Not even the worst cavern student would do even half of that... And the thing is... Given how insanely trained you guys are. You know all of that, you consciously decide to ignore and publicize extreme diving while ignoring the most elementary rules of cave diving... And with that you make video to teach people "which gas to use" or "which primary light to pick"? Seriously... What kind of role model do you guys set... Please do as I say, not as I do... People like you (so trained, so knowledgeable) should do better. You have a responsibility to foster save diving practices! You may be okay with that risk level, you may be comfortable breaking rules where you believe it is sort of safe. Your videos will inspire someone to swim in a cave without a line, to disregard buoyancy (for safety and conservation), that having a team separation is no big deal (you can always come back and find your mate). What you do privately, I don't really care. Please understand you are not sharing this video with your mates, and your recklessness may influance someone (probably far less trained) the wrong way... Anyway...I wish you to stay safe...

[@DrHarryH]

Yep, all fair criticisms. Hence my description of a warts and all look at the dive. I'm not hiding from any mistakes or inadequacies. I would suggest that by the time someone else reaches the point where they perform a dive like this they will know the rules and make their own risk decisions. Your criticisms about buoyancy, finning and cave conservation are not valid in my view given the equipment, cave topography and very hard marble of the cave...however I accept it looks ugly in the video. The line laying was better than it looks also, I believe the bit you are referring to is in a near vertical shaft and it was fine to follow on exit. The non-continuous line in parts is undoubtedly the most contentious part of the dive, and as I explained in a another reply it is a compromise made be able to do this exploration, but we made a personal decision based on many factors including the risks of patching line at depths between 150-200m. I would not encourage anyone to take such a short cut, and if it caused an accident I would not expect any sympathy. We are also working on how to efficiently avoid doing it again. I could choose not to show dives where we don't do everything correctly and perhaps that would be more socially responsible. Anyway I appreciate your comments.

[@TheMarcoflint]

@@DrHarryH don't get me wrong. I totally understand that we didn't climb the everest by respect every climbing rules. But there's a difference between you doing something where you can judge your comfort level and assess what risk you are comfortable with. And showing on an "education medium teaching less experienced divers which gas to use / which lights to use" arguable/dangerous practices for most. If someone start doing the same in a cave at 20m in Mexico or Florida, because if they think you can they should... It's a drama waiting to happen... It's nice to be "transparent" and owning your mistakes... Though you guys have a role model and the responsabilities that it comes with... I wish you that your work and channel inspire a generation of cave divers and explorers. People who know when and how to break rules don't need anyone to show them 😊. Anyway, I'm fully aware maybe the situation wasn't "as bad as it looks", my message was more about "teaching by example" than actually criticizing diving skills of someone who obviously know a TON more than any of us in the comments...

I have an open water scuba certification but I must admit i would need to brush back up on things before i went out again. for example i would’ve guessed these depths wouldn’t require such lengthy decompression

[@DrHarryH]

Best not to guess Knut!

[@knuthamsun6106]

nah, I have a good intuition for these things. i hear down in Yucatán there’s all kinds of awesome cave diving to do without any need for certification, experience, etc 😂

[@Vingul]

@@knuthamsun6106 Lol @ best not to guess + intuition… you happen to share a name with the best writer ever btw ;)

[@Bigmerc]

It must be wild to think you may be the first and last people in human history to see some of the caves youve seen. Im not a diver but I do hope cave diving grows into a larger activity. The footage is just hands down incredible

[@jasoncraig4977]

Exceptional work gents. The lack of hyperbole is a New Zealand delight.

[@Silicon-rp9zt]

That was the greatest introduction in KZbin history!

I hope people realize that these guys are in a class of their own. Only a handful of people in the world that can do what they do. 245 meters is an incredible depth. You can see why Richard (and others) were called in to save those kids. They are pioneers in this 'sport'. I really hope people donate to help with costs. They are making these dives safer for other divers

Came over from Dive Talk. Amazing dive! I couldn't ever cave dive myself. Had a ruptured brain aneurysm. But I love watching someone else do. Subscribed. Thanks for sharing this.

16hr deco gives me nightmares. Saw you on Dive Talk and super respect for owning up to mistakes along the way. Ego is deadly in anything like this, way to set a very positive example. Awesome!

[@DrHarryH]

Thanks I appreciate this. Not everyone so complimentary about showing the f%*! ups!

[@yjfuykyil]

@@DrHarryH I wish people like that could see them as opportunities to learn. To me it's very humbling to see one of the best in the world checking his ego at the door and, I guess take ownership of mistakes? Owning up to a mistake is a huge part of the learning process, in my humble opinion. And perhaps they should keep in mind how few people on earth do this at this level - this is astronaut stuff. I still remember thinking "I'm pretty bad-ass" after a 3hr deco flooded mine dive which makes me giggle a bit now. Levels to the game. Finally, a sincere thank you for pushing the limits of our limits and understanding, and letting us come along to see true cave exploration.

I take my hat off to you guys, you guys are great, I have a lot of respect for your work, thanks for a great film.

[@jeremyelliott7586]

Here via "Dive Talk" Channel. New sub. Thanks for your and your colleagues expertise and heroic selflessness! Even looking beyond the families of the Thai Boys that you and your group saved...it's hard to imagine the lives that will be saved from the body of work that you and your circle have been and continue to be dedicated to. Your positive influence on this world will far outlive your mortal being even if you make it 120 yo. Respect Brother....Respect!!!!👏👏👏👏👏

[@dustinroadway6108]

This is the most amazing thing Ive ever seen. These guys have more ability and talent than all of the government agencies and they are doing it by themselves. The diving technology is also amazing.

[@elliotw5918]

THIS, is excellent. I love everything about being in water but I know way more about the dangers of diving than a non diver should, which will keep me from ever doing scuba. I'm so glad that there are brave awesome souls like yourselves that do this for fun and take the time to video it and share with us non-divers. I love it!

[@georgeporge9505]

I have scuba dived in Gran Canaria and Malta...going next week to Malta for 8 dives...this video is amazing

[@SeahawkSailor]

Thanks for sharing this. Please continue sharing future adventures

[@BladeDoomer86]

Cave Diving! Guaranteed goosebumps and claustrophobia! Thx for this very well detailed narration. 😵‍💫

[@crystalm4324]

Really nice shots, clean diving. Congratulations on the new tunnels - can’t wait to see what’s down that hole 🕳!

[@lastro4999]

You guys are most couragous. Thanks for sharing it's the 3rd time I watch it and it is still breathtaking. Cheers!

[@esk1m0]

Don’t know why this was in my feed but wow. Now I have so many questions. Amazing video and even better commentary. Very brave.
