Their goal was to reach Steinugleflaget cave... the long way. How did two of the Finnish cavers die? How did the other three barely make it out alive?

I’m glad my hobbies include watching this from the comfort of my home
In the late 70s, I got into diving and was convinced by some experienced friends to go into a cave. I found the entire experience so terrifying that I never dove again.
The best part of cave diving is that you don't have to👍
Imagine being alone at the deepest part of the cave with the thought in your mind that your friend just died and having to make it out of the cave safely. I could never.
Great video! but I wanted to point out a couple things to clarify- Diving that deep there is no way they were breathing just oxygen. Gas compresses heavily at depth, at 440 feet that's over 12 atmosphere's of pressure. That means the gas is 12 times more compressed than it would be at the surface. At that depth breathing oxygen is toxic and deadly. Even breathing air (21% oxygen) is deadly past 185ft. Them being on rebreathers and at depths over 400 ft my guess is they were using a heliox (helium, nitrogren, and oxygen) gas. The oxygen levels in that mix would be VERY low and well below the 21% oxygen air we breathe at the surface. I don't want to get TOO wildly complicated but just wanted to point that out divers rarely breathe just oxygen, which is a common misconception. Also, you mention "out breathing" the rebreather, which is something that can happen but is easy to deal with/fix. You left out a critical piece of the story... When Patrick noticed the "signaling" from Jari he was having a seizure. The seizure is what kept Patrick from being able to assist and most likely the reason the regulator (the part scuba divers breathe from) had come out of Jari's mouth. The most accepted theory is not oxygen toxicity caused seizure's but in fact a medical emergency. Jari had a seizure the previous year and there was family history of the issue. When he became tangled it is widely thought the stress caused him to seizure. He most likely felt this coming on (Not something that would happen with oxygen toxicity seizures which happen instantly with no warning) and attempted to "bail out" (meaning go from his rebreather to his backup system) but was unsuccessful in making the transition before the seizure started, sadly. The jaw becomes VERY tightly clinched during seizures which kept Patrick from being able to insert a regulator into his mouth. Lastly, regarding "the bends" yes, it is caused by nitrogen that is absorbed by your tissues at depth and they will "bubble" from the tissue. Some "bubbling" is okay (it is how the gas is released and absorbed by the body to then be off-gassed) issues arrive when the expansion of the bubbles is rapid. Remember, as you go down the gas is being compressed (at their max depth nearly 12 times smaller than surface) so when you go back up the opposite happens. So these teeny tiny bubbles at 400+ feet will be 12 times larger at the surface. They expand exponentially getting larger as you go up. The faster you rise the more quickly these will expand, that rapid expansion causing all sorts of issues inside the body. The most deadly being an embolism.
Kai has been involved in at least 4 cave diving deaths. How is he not under investigation ?
Claustrophobia is a challenge to live with but also a blessing in disguise. It has kept me out of caves, both above and under water as well as other tight spaces.
The way you opened the video in the first 15 seconds was outstanding—it pulled me right in!
I used to really love scuba diving years ago. But never had the desire to dive where I could not directly shoot straight up. Cave diving just terrifies me, I would not even explore them on land.
Watching this i realize how much i love my couch and wide open spaces! Doing things like that makes no sense to me.
when it comes to underwater cave diving; there are no real experts!
Helllllllllll NO!!!!!! That’s crazy.

Cave divers with a loving family finding out a place called "Neptunes asscrack" with a 0% survival rate.
Why do you WANT to go cave diving? Cold, stressful, life threatening... is sitting on train tracks until a train comes too easy? No, seriously, why have a hobby where your death is a very pressing variable at all?
and before we continue this funreal i would like to thank our sponsor💀💀💀
I never go into anything smaller than my car
the ocean and water is so pretty and i find it beautiful and peaceful, but it can end a life so quickly :( rip those who lost their life. ❤
I don't blame them. Losing a friend hurts
No divers ever go to 1640 feet and turn around; they all stay at that depth (1:23)
