Mapping an UNEXPLORED Cave for the first time!

[@FamiliarAnomaly]

Not a cave diver but came to appreciate this fact - every time they dive there is a chance they find something that is "pre-great flood" or the 135-200ft rise that happened 10k years ago. That makes it extra exciting when it's a new place.

[@DIVETALK]

Thank you for the shoutout! Looks like there’s so much more cave left to be explored! When are we going back?!

[@Pnwdive]

I love how blueworldtv , also dive talk stated they’ll never cave explore now they’re explorers!!!! 🧭 it’s amazing!

[@connorvenegas]

Diving with you guys and Jonathan would be amazing! While I still have a long way to go (both skillwise and financially), I intend to get trained on a Kiss Rebreather someday and at the very least, get cavern certified. Currently, my highest certifications are AOW and Nitrox 40% O2, with 75 logged dives. I'm also looking to hopefully get into an AAUS Scientific Diving Program this summer through my university, since I am a third year Marine Biology major. It's always awesome to see my two favorite dive channels working together. You both have inspired me to take my diving career beyond the recreational level as there is so much to discover in the blue world! 🐠🐟🦭🐡🤿

[@BlueWorldTV]

Just keep diving!

[@BlueWorldTV]

Not our fault. We never turn down a cool invitation. And exploring under the supervision of an expert is a lot different than doing it alone.

My cave diving instructor that i got my certs and leasons and training from and i been with him and his wife for my carts since day one of scuba lessons all the way to my cave diving certs in joining him his wife map out a unmarked underwater cave and its my forst time doing it im nervous but they told me it will be fun and exciting seeing stuff for first time ever seen by humans and they gonna lwt me run a few lines for my forst time ever as well cant wait your video made me a little more at ease. And i got to initial and number the survey spots woth the line markers as well and it was so cool knowing i documented and laid that line and saw that lart of cave for first time ever seen by a human and my initials are now engraved for everyone to see for ever and years to come. All my numbers i placed was personal to me like the month i was born 06 my mom and dads birth months and two brothers birth months my wife and i anniversary year, and my new borns son birth month on one and birth year on the following one which was exciting. And my instructors wife found a new species of a type of crayfish that has never been seen before in united States and only thought to be native to and live in this one tiny little creek in Australia so that was exciting

[@heart_of_a_Celt]

These videos are so well crafted they could be in the cinema, such a joy to be able to watch them, but this one in particular was also scary as it brings home to me how critical those lines are, they are really life lines! I know there are lost line drills, but boy if anything happened to the line.. But still national geographic level documentaries on youtube is a gift. Thanks again so much for making these truly incredible films! I call them films as their quality is way beyond video!

[@TheRealWulfderay]

Congratulations, guys! That's quite the bucket list item! Ah, man, I just saw the part where Mike was using the Petrel attached to the clipboard for the surveying. As the guy at Shearwater who wrote the driver for the compass chip on the NERD (later ported to the Petrel) I am incredibly proud that our compass is being used for something this cool. What a treat to see.

[@BlueWorldTV]

That little rig he has with the shearwater mounted to the slate is super slick!! You get compass and depth from the same screen at the same time. Very easy!! As someone who LOVES LOVES LOVES all his Shearwaters (I have 4 I think) I just want to say to you thank you for making the best dive computer the world has ever seen!!!

[@TheRealWulfderay]

[@BlueWorldTV]

Thanks! Yes that's totally true. Filming really slows things down. When we work with a dive operation or a dive expedition for the first time, we explain to them that we are not here to do a dive. We are here to make an exciting episode about a dive...and that's totally different. It takes way longer.

[@Dboy10810]

Great, very interesting video. I did not get what you just said about how Mike calculated the distances.

[@BlueWorldTV]

Yeah, we should have covered it better but we didn't have any footage of it. Before the dive, they put knots in the line every ten feet. So once the line has been laid out in the cave and you are doing the survey on the way back, you count the knots between tie-offs to get the distance. You have to kind of guess on "half knots" or "quarter knots" because it rarely ends up being exactly an integer number of knots from one to the next tie-off.

[@michaeln-bd3vk]

amazing video ! may I ask how far the spacing was between knots on the survey line ?

[@BlueWorldTV]

Ten feet is the standard.

[@stephenwinter8892]

Greetings from southern Ontario Canada I really enjoyed the video very educational but the point of entry to the cave under water is squishy and smelly 😮I always thought a sidewinder was,something different, I don't know what it is like to be able to navigate through this cave like atmosphere but several meters under water

[@ssimitz]

I never knew that you guys also went ahead and got Cave CCR certified?! Didn't you want to film that training as well?

[@Skunkiboi]

That thing with the spool works only when you have thin gloves on. Or none at all. But in icy water its a challenge to get the rope out of that hole.

Wish I was with you! Hi from the D.R.

[@BlueWorldTV]

Good cave diving there?

[@LoveCaveDiving]

@@BlueWorldTV Yes! A good variety too. Some decorated Like "Cueva Taina" and "El Asfalto". Most have no flow. We even have the infamous "El Dudu" which is a real nice dive. No real restrictions except where the Italian guys went. If you ever come let me know. 😊

[@GCCG76]

Pretty amazing to have your name used to name a section of the cave! I’m curious to know the land thickness of the above streets..is it safe to suggest the roof won’t ever collapse? Scariest thing for me is that the flashlight beam does not reach an end..it dissolves into the darkness of the cave…seen too many movies 😅 however spooling the lines would definitely take my mind off the edge and concentrate with the task at hand..stay safe!

In some places it's only like 20 feet of rock above.

[@pricediver]

How do you weight yourself while on CCR, I have been using mine and my trim is not very good.

[@BlueWorldTV]

It takes a while to get used to it. AND....the longer you have been diving, the harder it is to get used to. That's because we are so accustomed to using our lungs for fine tuning buoyancy. When you approach something, you can just inhale a little and you rise up over it. Then exhale and you sink back down. But on a rebreather, that doesn't work because it just moves the air around from lungs to counterlung. It's really hard to get used to. As for weighting, I have found on the DiveTalk Go that my weight is about the same as open circuit because the buoyancy of the lungs is roughly cancelled by the rebreather and the O2 cylinder. On the SideWinder, which has more loop volume, I use a couple pounds more than open circuit. I generally prefer steel tanks to minimize how much lead I have to wear. But in warm water, with a wetsuit, sometimes the steels are actually too heavy and the aluminums are better.

[@ftothel794]

you laid MILLIONS (of micrometers) OF LINE, MAN!!! that's absolutely cool!

[@BlueWorldTV]

[@brandonm1088]

Hey Blueworld Team, I noticed John and crew use LocLine and foam instead of float arms. Is there any technical reason for that? I'm about to balance my own Nauticam housing and I haven't seen many folks using locLine for lights. Also interested in experienced folks perspectives

[@BlueWorldTV]

Because I shoot video, I'm not using big heavy strobes, but relatively lightweight BigBlue video lights. So you don't need big heavy ball arms that have to be clamped and unclamped to adjust. I like to be able to just move the light. The LocLine is stiff enough to hold a video light but I can just reach up and adjust it easily. Saves a lot of time since I adjust my lights for nearly every shot.
