Awesome videos! I really appreciate not having some random music 🤫
Some serious diving you are doing in this mine. Really enjoy your videos.
Cave diver buoyancy skills are Second to none
Wow, that's some serious diving! Especially if you take the cold into account.
Man thought I was brave. Been skydiving a lot, raced motorcycles for years and am a pilot who has flown a lot of aerobatics. This might be the first thing I've ever seen where I said oh hell no.
Amazing dive - so interesting to see the evidence of human activity still sitting in situ. Thanks for filming, and sharing with us. Safe diving! M
#divetalk look at these legends just killing it !
It’s like they are going through old cities or something like that.
I keep seeing things like bridges and old buildings and ladders
Very nice dive and very nice video, would love to come up north some day to dive some nice big mines 😁
I wish you guys would turn your lights off just to show how dark it is in there.....I've been inside cenotes in Mexico and even the mouth of just the beginning of a cave and I still can't describe the darkness/silence you experience. What you guys are doing here is so dangerous and amazing because even with all the safety and discipline it's still may as well be space 🌌 lol cheers from Canada
Love it Lads, Keep them coming
stunning!
Good work!!!more videos!!!
It's fascinating to think some time ago people used to walk around there and use those stairs.
When you look at the stairs, railings and drops there are in the mine the healt and safety regulations were not at current level back in the time.
If I ever win the lottery I'll join you guys!

Epic
I believe this CNS is beyond than 150%
At 100% we have a O2 break. Shearwater starts giving warnings when you close 100%
That looks pretty awesome but it's a nope for me!
You are basically mixing up the two most dangerous ways of diving. Diving with trimix and cave diving. And that's without even mentioning the dry suit. But how awesome are these kinds of expeditions 😉😎
I personally would feel safer doing a deep mine dive than doing a deep normal dive, what if the BC inflator get stuck, in a mine a roof will stop me but when not in a mine and i dont act quickly enough im dead
@@ryba7846 At least you are able to return to the surface. If you dived on trimix you will certainly be helivaced to a deco chamber. But you can still survive, in cave, you just stay there.
@@Exploremore658 Im not sure but i think that if you do an uncontrolled ascent from 100 meters its a certain death
@@ryba7846 The effects of DCS are delayed. So you have at least a chance of survival. The only case where death is if you are in a deco chamber and it gets de pressurized
Nowadays a dry suit is a standard in open water diving in Finland and after a while it's much easier to dive than a wet suit. Even open water courses are typically done with dry suits. With the Trimix you need to be able to control your ascend rate very precisely and you need to be ackurate with the deco stops.
Pretty cool dive! Did every diver have all bailout on them for the entire deco? Or did you store it somewhere? What are the practices for that much bailout?
Yes we do have. Basically you carry the breathable bailouts at top. You can leave the shallow bailouts on route if the return route is the same. On the way back you can nose clip the deep bailouts to the JJ's bottom frame so that they do require less space.
How do you keep up diving almost 4 hours in water with a temperature of 4 degrees Celsius? With heating I can stand it for, let's say 1,5-2 hours maximum..... How do you do that?
We have a habitat and that helps a lot but we can manage without it. We had same question before so I just copy paste it to here. Here is what gear Tero has. "I have three socs. Two Woolpower socks total 600 g/m² of wool and also Weezle Extreme+ socks. Then I have Woolpower Long Underwear 200 g/m² and fleece long underwear. On torso I have two Woolpower Turtleneck 200 g/m², Woolpower vest 400 g/m² and NLS heating vest. On top I have Weezle Extreme+ undersuit. On my hands I have wool mittens. I dive with an Ursuit drysuit and have rubber Loitokari drymittens. I use two neoprene hoods 5 mm and 3 mm."
@@arcticicedivers7001 And how is his flexibility / mobility with all these suits? 😳😂
Actually quite good.
@@arcticicedivers7001 And what’s the capacity of the heating canister? 40 Ahr or so?
Our next video is about habitat. We changed the depth of the habitat so we needed tools like monkey wrench and chaing hoist. Gear what we had was quite normal that we have at deep dives. Tool handling is guite good with mittens too.
Do they not feel phobia or something?
😯
What type of canister did you use in your JJ,standar?
We are using standard JJ-CCR axial scrubber
@@arcticicedivers7001 what's te recommended time for this scrubber?
@@j.m.k8327 3 hours, but actual scrubber time depends heavily how hard you are working during the dive. Our limit for deep dives is 5h since most of time is spend in deco.
How did the mine flood?
As I understand the mine flooded slowly when they stopped pumping the water away after the mine closure. There is a place called pumping room for example at 48 m water level but at least at that level the pumps have been removed. There are just pump beds and some pipework left.
Why is this so deep?
We were trying to find a new route at that depth.
@@arcticicedivers7001 great! But safe is the first.
