Learning Trimix to Dive DEEPER

Diving deeper than recreational limits requires a special kind of gas blend known as trimix. In this episode, Jonathan takes a trimix class with renown technical diving instructor Doug Ebersole and gets to visit a famous cave called Eagle's Nest! (Technically, the class is CCR Normoxic Trimix).
WARNING! THIS EPISODE IS FOR ENTERTAINMENT ONLY. SCUBA DIVING IS DANGEROUS AND REQUIRES TRAINING. ALWAYS SEEK QUALIFIED TRAINING.
JONATHAN BIRD'S BLUE WORLD is an Emmy Award-winning underwater science/adventure series featuring underwater cinematographer/naturalist Jonathan Bird.

[@ivoryjohnson4662]

Doug is a down to earth person has always made me feel at ease. Paradise Springs is a beautiful place to dive

[@BlueWorldTV]

I very much enjoyed Paradise springs. It's a nice place to train or go for a "cave-like" cavern dive. Not crowded either. Doug likes to teach there. And yes, I agree about Doug. A very patient and calm instructor. Also a good teacher. He really is a cardiologist as his real job--so he is very smart and good at communicating. I can't recommend him enough!

[@SubTo_HabRBLX]

@@BlueWorldTVHi it’s Insane!! That you still heart comments videos 15 years ago.

[@buckyplayz1919]

Jonathan is so humble and real. “Am I nervous?……… yes”. If you’re not nervous, than you’re lying 😂😂

[@CapybaraCM]

I think if you’re not a little nervous then you don’t understand the significance of what you’re about to do. I still get little butterflies as I’m about to giant stride. Even after a number of years diving recreationally.

[@buckyplayz1919]

100%. Complacency leads to errors. Some stress is good, for sure. My son and I dive here at Chassahowitzka, Buford sink, NOT eagles nest yet,, won’t be anytime soon for me! I take the Buford sink very seriously, even though we’ve been in it a bunch of times. If you’re paying attention to this wonderful Blue world group, Jonathan Bird(Byrd ?). This guy has done A Ton of caves !!! And he can still admit that he’s a tad nervous. I look forward to these episodes! Such great stuff!! Very well done, very well explained in layman’s terms. Top Notch! I had to take a trip down to Hole in the wall adventures , based on this episode, only about an hour from me. Awesome place!!!

[@tenzinsmith7991]

Eagle’s Nest- no place like it. Instantly recognizable

[@BlueWorldTV]

I want to go back now and do a full episode there.

[@CubanazoJB]

@@BlueWorldTV Yes !!! We’ll be waiting for you guys !!

[@benderbendingrodriguez420]

I love the training videos just as much as the actual diving episodes themselves! Jonathan is just checking off his scuba list at this point😂 also happy 100th cave dive!

[@BlueWorldTV]

Thanks! I enjoy doing the training because I like to learn new things, and training is often quite interesting to our audience as well.

[@jellyboi7318]

Favorite youtuber ever! Very good Quality

[@BlueWorldTV]

You are the best, thanks!

[@craig221]

i love this show. thank you for putting this out on youtube so everyone can watch.

[@hirzuko]

I always stop by now and then to watch Johnathan’s Blue World, I would’ve never found his channel if it wasn’t for my teacher who showed his videos in class around 8-9 years ago. :)

[@BlueWorldTV]

Smart Teacher!!

[@ahmedmahomed]

I really am quite upset about why such nice KZbin channels have been getting so less views compared to their previous amount.

[@BlueWorldTV]

Tell me about it! Our channel always has less views in winter, but this year it's ridiculous. I don't know what's going on. I know the algorithm responds to quantity more than quality and we have no been releasing as many episodes recently (because we are busy working on a new IMAX film) but it just seems like KZbin is going down the tube!

[@ahmedmahomed]

💯 😢 ❤

[@buckyplayz1919]

From Massachusetts too, live in new port Richey now. Buford is like an every weekend thing for my son, myself not as much, but it’s awesome. It’s so funny, we just did paradise spring not long ago too. It’s way nice living down here. Don’t miss Mass at all Awesome episode!!!

[@BlueWorldTV]

I keep telling my wife that I could be perfectly happy living in Florida cave country. Everyone in the north imagines Florida is all like Miami or For Lauderdale. They don't realize that cave country is more like New Hampshire with no snow and CAVE DIVING!!

[@buckyplayz1919]

My son and I just did tech 1 and cavern in high springs. It was nice to be able to just drive up for a couple of days, he moved here to the Tampa area from Brewster Mass. he doesn’t miss it at all. I came here in 2003 and did cavern training,, starting all over for my son!!! Love it Jonathan, the videos are so well done and informative . Even my non diving friends and family are so riveted You inspire a lot of people , and you guys seem so nice!!! Hope we run into you at Buford. I use a hand truck for my doubles to get out there , I’m a few years older than you ,, man I’m impressed with all of your diving accomplishments. Inspiring. God Bless you guys. Can’t wait to see the deep diving episodes!!!

[@IPADD12345]

Never gonna forget this iconic intro!

[@benderbendingrodriguez420]

"I think in the old days no one lived long enough" 😂😂 bahhaha too true

[@BlueWorldTV]

Zimmy thought we should take that out. But honestly, the reason that milestones are a big deal in cave diving is because back in the early days of cave diving, it was a very dangerous sport and they celebrated living through it. Now we have special equipment and rules, and it's very safe of course. But we still celebrate the milestones out of tradition.

[@benderbendingrodriguez420]

@@BlueWorldTV I'm sure astronauts feel the same! Or plane pilots! Advancement in technology has made these things safer... but the danger level is still always at max! That line specifically just always reminds me of people who "want to live in a different time" and that said time is usually when humanity was lucky to push past 40 years old😆 history isn't as always clean as it is on the movies/textbooks

[@joshisajedi2461]

The quality of this channel is top notch! It reminds me of something I would watch on Saturday mornings as a kid. Congrats!

[@diegomaldonado5068]

I am so excited!

[@weatherkop]

I always enjoy watching this channel because my father and uncle used to cave dive back in my teenage years. We would all go camping as a family in North Florida at Ginnie Springs. Plus the fact that the host looks like and has similar personality to my uncle, he’s no longer with us but was a great influence on my willingness to explore, God bless him and you on your journeys!

[@ericramosmd]

Congratulations, great job on one of the pinnacles of caves!

[@BlueWorldTV]

Thank you very much! Now I want to go back and explore it a little more for another episode.

Doug is the man. A wonderful human being, and terrific instructor! Highly recommended!

[@Saxatillis]

CCR TRIMIX! Congrats!!! I saw the intro and said "Ha! They went to Buford". From just the 2 second shot of divers and the cave celing, i knew exactly where you were 😂. Its a long walk to get there but soooo worth it. This class opens many more dive spots in The Blue World, cant wait to see where you go next. Be safe

[@BlueWorldTV]

Christine is not super happy about it. Fortunately, I hate doing deco (so boring) so I'm probably not going to get addicted to deep diving. But we have some deeper wrecks in the great lakes we want to film plus an upcoming trip to Truk so we will be able to use our trimix skills a little. Merry Christmas!

[@avramcollins6409]

Nice call on this episode! It was fun to watch how your course went, I'm excited to see what you guys have up your sleeve for the super deep dives! Filming some angler fish? Haha..congrats on your new Cert!

I know right???? That was awesome.

[@John-sn4hl]

I'm so excited to see where you go next!

[@addohm]

That rescue is even harder with two dry suit divers. On my exercise my diluant quick disconnect came undone somehow as I was towing. Before my counter lungs went completely flat I had to safely park the diver being rescued on a wall/ledge, bail out and finish the rescue. When you clip off your bailout/deco/stage, ALWAYS crack the valve to pressurize the regulator and close it.

[@robertcampbell7662]

That’s awesome dude!!! Congrats can’t wait to see the videos using this cert!!!

[@ExplosiveBrohoof]

Can't believe I missed this video. Had no idea nitrogen was a narcotic too! Learn something new every video. Looking forward to the deep dive videos in the future!

[@Teampegleg]

It is fun trying to explain to people that with proper gas mixes deep diving for the sake of deep diving is largely anti-climatic. You get to your planned depth, and the only thing different is how quickly the gauge drops. On my first truly deep trimix dive, I was at 182ft in a cave, and I found an old DIR style knife, and I still remember clearly the mild rust on various parts of the blade. It felt no different than any other dive. I love how you downplay Doug's job as a cardiologist. For those that don't know he was one of the leading experts on closing PFOs. If you think you are a have PFO he is the man to see. Also your dive at Eagle's Nest was a cave dive per the rules. While there are disagreements about total linear distances almost every agency agrees the cavern zone ends at 100ft of depth regardless of the ability to see sunlight. So both your dives at Buford and Eagle's Nest are cave dives. Though since they are training dives, I don't think they count toward the Abe Davis award or access to dive count restricted sites.

[@BlueWorldTV]

I agree...the lack of narcosis means that there is no real feeling of being deep. The danger in that is that you don't have the "paranoia" of narcosis to remind you to get the heck out of there. The deco piles on fast! But with the rebreather, the deco also comes off fast once you get shallow and crank up the PO2. We probably should have put more emphasis on Doug's "real job" but from the perspective of this crowd, his role here as an outstanding instructor was really more the point. Doug loves teaching diving and he is really good at it, so we wanted that to be the focus of the story. As for the 100th cave dive, to me it doesn't really matter what officially "counts" or not. I have no intention of applying for an official Abe Davis award. I don't need a certificate that says I did what I know I did. And if I did apply for it, I would wait until I had like 120 cave dives so they wouldn't reject me! LOL!!

[@LoveCaveDiving]

Congrats on your 100th cave dive. I will be going back to D.R. where I live in 3 weeks. More cave dives for me! Looking forward to your upcoming episodes.

[@jidai4837]

Love these content

[@scoobertjoo]

WOW, that greenscreen looks great!

[@BlueWorldTV]

Not greenscreen. That's an actual set in our office that Noah built.

[@TauchEin]

You should have explain why it‘s a good idea to use trimix in a rebreather these days - the helium is gotten really expensive, too expensive to use it open circuit in my mind.

[@BlueWorldTV]

That is absolutely true, BUT this has created a bit of trouble. There are a lot of very experienced open circuit deep divers that are switching to rebreathers just to save money on gas. But they are jumping right back into deep diving on the rebreather without getting enough practice in shallow water. Just because you have done 400 foot dives on open circuit for years doesn't mean you should immediately start doing that on a rebreather. So there is a lot of concern in the diving industry about that. Saving money is not necessarily a good reason to dive a rebreather.

[@coralpilled]

congrats on the certification and 100 cave dives! Do you know how many dives total you've done?

[@BlueWorldTV]

My total is around 5,000 dives. It's incredible to me that I have been cave certified since 2015 and I have only just now reached 100 cave dives--after who knows how many cave episodes of Blue World and an entire IMAX movie. But when you don't live anywhere near cave diving, it takes a long time to get to 100!!

[@ianstockdale964]

Great video 👍👍

[@BlueWorldTV]

Thank you 👍

[@kevindavison6019]

I'm surprised you hadn't already had this cert with all your experience. I thought that once one got certified for Decompression diving this was just logical next step. It looks like some additional drills got thrown into the mix. I assumed the jump from regular deco to tri mix was just one of classroom theory and some practice dives to get used to the computer setings.

[@BlueWorldTV]

That's what I thought too. For nitrox, all you do is some classroom work to understand the theory, learn the math, and how to set your computer. LOL. I mean, breathing is breathing...so why would you need to dive it? HOWEVER....the difference with Trimix is not the gas itself, but the safety protocols associated with deeper diving and potential gas switching. Additionally, since I did the course on a rebreather, I have to learn a bunch of bailout protocols as well, since you have to learn what to do if something goes wrong on the rebreather.

[@michaelnemchik826]

[@hikeDiveEat]

Did each of your sidemount cylinders contain trimix? Great video. Thanks.

[@drizer1]

His stage bottle was likely EAN50 for the gas switch on the bailout dive.

[@hikeDiveEat]

Thanks

[@BlueWorldTV]

Yes, both sidemounts were trimix, and the stage bottle was 50% O2. The point is that if you have to bail out of the rebreather, you have plenty of trimix bailout gas, but once you get up shallow again you might have a crazy amount of deco, so you need a deco gas for bailout. If nothing goes wrong, you never need it. I did the entire class (three days) only refilling the sidemount tanks once, because you use so little gas on a rebreather. And the only reason we had to refill them is because in the class you do a lot of bailout drills that use gas.

[@hikeDiveEat]

That’s so cool. Looking forward to that same course in a few years.
