How many specialty diving!!
drysuit, ice, night, deep, full cave, trimix
, dpv, ccr diver courses simultaneous
Outstanding video!!!
Very very impressive. Many specialties which I don't have yet 👌
do you need ice when you are cave master?
I imagine that all of you are just a slight bit crazy. Super cool dive.
Excellent video as always! What an incredible place to dive.
Absolutely amazing !
Thanks for taking us along for a great dive.
That looks amazing. I wish we had dives like that here in Australia. Good work on a successful dive and quite a nice circuit of the mine
You have nice caves in Australia.
I'm in and not even seen the whole film yet 👉 👍 🔔 👈 👍 👌 👊 🇬🇧
Just been studying the mine of Wiki - quite some history there!
Great job Buds
Awesome !!!
Great Video...….
Wats up,so so nice!!RESEPECT!!
What a great Video! Can y show us next Time y Divin Configuration and Stuff?....mabey?
Thx for this excellent Video!
Would be great to join you guys one day!! 💯
Diving in Moria.
Really enjoyed that, Thanks... Ye are so lucky to have this Dive site, and especially for after work :) 1 Q. can you tell me why 1 JJ Diver has the Deep BO on Right side? Thanks for a Lovely experience
We sometimes have two deep bailouts so one is on the left side and other is on the right side. We usually dive to the 90 m level but sometimes we go deeper. In this dive Pasi has mod 100 m tank on the left side on mod 90 m tank on the right side. Tero also have two deep bailouts.
What is that high pitch sound? Is it a sonar or a positioning system? Or just a capacitator in the scooters? Awesome movie!
It’s scooter
Are JJs compatible with M-48 MOD-1? I'm assuming that's the facemask you're using for comms at 3:15?
Amazing footage! Where is this exactly?
from other uploads, this is in an old mine near Montola, Finland
Looks like a lot of deco payback for not much time caving.. How do you pass the time waiting to surface?
True, not that good dive efficiency, most of the time hanging in deco. We can chat in the habitat and that helps to kill the time
Which scooters do you guys use must be powerful pulling fully kitted out diver with 3 side slung cylinders
We use Northern Ligtht Scubas's scooter. www.northernlightscuba.fi/shop/68540/?lang=en
What heating system do you use? 2h+ in 4° is quite long...
We use Santi and NSL heating vests. We also manage quite well 3-4 hours dive without heating vests.
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 Santi 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."
What I am not able to understand (not a diver), how you work with waterdepths. Initially you come down, let's say, 40 m, then you swim into a tunnel and you have, maybe only one m waterpressure on your body, but you are coming closer to 90 m underground overall. And when you swim from this tunnel into another "hall" you can have instantly a 50 m watercolumn over your head again. So in many videos divers always count the overall depth for their ascentpauses (decompression stops). Why is that?
First of all, this video is time-lapsed, so you don't see everything. However, when you do the paper math (i.e. when you're learning and/or planning) you assume a square profile dive. Meaning that you spend all of your time at the max depth. This keeps things very conservative. In reality the depth is variable (multi-level dive) and you can just follow your computer to determine your ceiling (mandatory decompression stop) and duration. Diving with a Shearwater makes things very easy, when you can see CEIL, TIME and TTS.
Correct! You do a basic plan with forexample the V-Planner but you execute the dive with your primary and secundary Shearwater.
The depth is always measured from the surface, because the pressure increases linearly with depth. It doesnt matter if youre swimming through a narrow corridor or if the water is actually "on top of you". Its a bit unintuitive, if youre not used to it. I highly suggest you google "hydrostatic paradox" and "communicating vessels" for a more thorough explanation.
So essentially if you were to dive down a straigh shaft to 40m and then swim horizontally into a narrrow tunnel, so you only have 2m of water actually above you, you will still experience the pressure of being at 40m depth.
@@tolga1cool wow, your answer actually helped me understand the OP's question. I didn't realize that's what he was asking. Good job! :)
So quite!
where did you mount your go pro? it recorded in a much better angle than the paralenz mounted on the helmet
GoPro is mounted on scooter (dpv) with two 100W LED lights.
What drysuits do you guys use? I imagine any leak in water that temperature is going to be a bad day!
Look's like Ursuit and Loitokari dry suit's.
We (Pasi, Ari-Pekka, Tero) are using Ursuit dry suits't. Our friends use also Loitokari (rubber) suits. Quite usually we have minor leaks in our dry suits. In case of large leak we nowadays can go to the habitat.
@@arcticicedivers7001 can you recommend the dry suits from ursuit ?
Can you dive that deep with a wetsuit
@@adhamhwomble8345 It's not really a depth issue as much as it is a temperature issue. This is arctic diving. I can't imagine there's really anywhere in the region that these guys dive with a wetsuit. In places like the southern U.S. and Mexico, you will see more people diving with wetsuits unless they're deep diving or diving for an extended period in waters below 72-75F or so.
Nice Video...but I can’t see any backup dpv?!?
You are right, we do not have backup DPVs. If DPV fails, we tow. Extra time used for towing is added to our bailout gas and deco calculations
@@arcticicedivers7001 ok...thank you
pedri had a loss, no check at 6 meters?
We usually do the in-water checks close to surface
Hello, there is a plan if the scooter fail?
If scooter fails, we tow. Delay due towing is part of our bail-out calculation.
@@arcticicedivers7001 aah ok. Awesome videos!
Очень круто.
Why was that place built?
