[@BlueWorldTV]

Hey you guys! So many things to say about this cool video! I love it when you guys make videos about your own dives....always entertaining! First of all...Woody....I'm jealous of your virgin cave line experience! So amazing! Gus, I'm so glad you are OK. That situation could have gone so badly quickly. Being honest about what happened and telling everyone so we can all learn from your mistake is a very valuable. The camera work in the habitat was great, and I love the Dive Talk sticker! So I guess Edd is a patron saint of deco now? I would love to do a Blue World about this expedition, but I'll be the shallow water guy.

[@OldManther]

Would have been very easy to not mention Gus's issue, but really glad you did. As someone starting down the technical diving path, learning from the experience of others is invaluable. Thank you both for your contribution to the diving community and for always being real, direct, and honest about ALL the situations you react to, especially your own.

Damn, can't express how happy I am that you managed to get out alive Gus. That was a scary moment indeed. So crazy to think that without all training, safety discussions, and quite frankly a bit of luck, you probably would be dead..

[@MrSmithington]

Gus, your experience continues to grow, we’re so glad you made it out okay, what would we do without you keeping Woody in check, he’d run rampant on the channel😂

[@lisalovesdiving]

It‘s really hard to see Eric so happy and smiling in this video after knowing what happended to him. RIP and my deepest condolences to everyone who knew him, and of course his family! Also really glad that Gus is okay. Definetly puts things into perspective.

[@CubanazoJB]

Just saw this vid.. sad seen Eric there so full of life and doing what he seems to love !! RIP .. peace to his family..

[@helgaratbone1691]

I was on the edge of my seat listening to you retell the story of your dive, Gus! Glad you’re ok!!

[@maskotep]

Congrats to Woody and Gus actually getting to do some cave exploring. Was a blast to watch! So glad you are ok Gus.

[@myusernameis1998]

oh man you guys should totally make a series where you play Subnautica! Two extremely talented cave divers playing a deep diving exploration game! i would binge watch that!

[@brandonbruns2297]

Gus I'm glad you made it out ok. I don't think Dive Talk would be the same without you. That being said the commentary while you were narced is awesome. Also, thanks for the member shout-out at the end. That was awesome.

[@TheRealKurt051]

I’m so glad the mission briefing was included, that shows the detail planned this ain’t no picnic only badass divers allowed!!!

[@levicox9611]

It's so crazy woody got to actually lay line in a legit never explored cave, that's amazing!!! And I'm happy gus made it out ok!

[@brennatarpley6010]

To my favorite channel - I love you guys, thanks for another incredible video. Gus, I am so glad you are ok.

[@DIVETALK]

Thanks so much!

[@TheRealTomLauda]

Gus is definitely the guy i would want by my side in a difficult dive. He never loses his cool, even when in trouble. Each time, he was so cool, the others didn't even noticed he had an issue until he talked about it. That's the kind of guy you want with you in tough situations.

[@chryseluna1648]

Sounds like a learning curve was had, good watch, the habitats are very interesting, and those orange large plastic screws, just so many different tools, it truly is all very interesting to watch, love it, thanks to all of you 👍🏻⭐️

[@lolalenoir3048]

So glad @divetalk won’t be needing a new co-host, it just wouldn’t be the same without you, Gus! Thankfully from now on there’s a picture of your guardian angel watching over you in a ripped shirt from that habitat! So reassuring 🤣🥰

[@FluffyBunnyArsenal]

In vertical rescue, we always had a saying to help us remember to double/triple check rigging, "Complacency kills."

[@LoveCaveDiving]

This was one of the best videos yet! Love the debrief. Love the dive. Love woody's antics. Gus' experience made me nervous. I have had small issues but nothing like that. 3 weeks ago I was exiting the cave and something felt weird. Like a hose twisted which happens from time to time. No big deal. I'm wast deep in water and I take my helmet off and the hose was on the top of my head under the helmet. Made me laugh. I have a go-pro on my helmet and I bumped it on the roof. I checked the go-pro to see if it was still running and it was. The hose went on top of my head and I put the helmet on it. How in the heck I didn't feel it is beyond me.

[@lanarita11]

I really liked how you included your meeting footage at the beginning of the day (also great dog!!). Listening to your experiences really puts the interviews you made with Mike and Edd into perspective for me (I'm not a diver). Can't believe how skilled they are. I'd love to see more interviews with them about their experiences. But anyway these videos you made are one of my favourites on the channel, it's great to see how passionate you are about diving:) I wish you many many more great trips, hopefully without scary issues!! Gus, I'm very glad you are alright. Pls take care both of you.

[@realvisiondrone]

Wow guys! You are indeed lucky dogs 😊.

[@cynthiafarris1051]

Awwe! Lol Ed is always with you guys. You know what this means right? If Ed is, like Blueworld said, the Patron Saint of Deco, you guys have to put him up in every habitat and cave you dive in. Lol, I'm so excited for you guys every time you do something like this. Congrats on setting line in a virgin cave Woody (there's gotta be a better way to say that) and Gus thank God you are still with us and you wanted to show off your trim. You were so chill while narc'd, "I wonder if Mike can see how good my trim is?" Classic. Great episode as always guys thank you.

[@jacksnedden25]

Gus, so glad that event turned out well! The physiology mental gymnastics were challenging to follow while you were describing your experience; and under the conditions you were in, your training and experience save you that day....Amazing!

[@bandcookie88]

I'm 12 seconds into the video. As soon as I saw Gus with the regulator, I thought it would be a fun way to intro with helium, LOL. I guess Gus and I have a similar sense of humor on that one! Update: Glad you made it Gus! I'm sure that was unnerving, both in the water, and once you got back out and realized what happened. Congrats on the laying new line Woody! It's a great accomplishment and an acknowledgement of your skill. To both of you, I say, 'Excelsior'!

[@tamo9520]

This is soooooo freaking interesting! So amazingly interesting!! The brains behind all of this is genius! "" GENIUS "" !! Gus, your story is off the charts! Off the charts! It's nice to see you! Honestly! It's freaking nice to see that you are here with us! Yup, it's definitely experience over the years that helped.

[@timgosling6189]

Special thanks to Gus for sharing his experience. The set-up issue applies to anyone using a new rig, you showed how easily even experienced buddies can lose contact, and the description of mental impairment is salutory. With hindsight we can all say "just go up!" but the human brain doesn't work the same way when impaired with either hyperoxia or hypoxia or nitrogen narcosis; we need to be in that happy place in the middle to think straight!

[@amyr6309]

So glad you made it back and are okay, Gus. Learning is a lifelong process. Woody truly is a caring and loving guy. Those habitats are really cool. Who would've thought you could converse and watch a movie while decompressing in the water. Nice decor touches - Dive Talk, Love, and Edd.

[@stephono3]

What an incredible story and a great example of what happens to your brain when narcd. So happy your training and experience allowed you to survive.

[@fuzzyboots123]

As someone with zero clue about diving, when you first mentioned habitats I was like "oh cool! There's animals around" 😂 also glad you made it out Gus! What a close call

[@CKOD]

Gus skillfully swimming though each layer of the swiss cheese model, only to peek though the hole in the last one, and contemplate it for a while before turning around. Maybe time for another layer or two? Can you get color coded hoses or fittings? I.e. Black hoses go to rebreather breathing tanks, blue hoses go to Y, yellow hoses go to Z etc? Obviously "Know your rig and dont be bad when putting it together" has its place. But if something sticks out to you because you're hooking an air cylinder to a black hose when it normally goes to a yellow hose, it can set off the mental flag of "hey let me look over this one more time"

[@DIVETALK]

We are making adjustments so this doesn’t happen again.

[@Kwisten050]

Really glad you're ok Gus. I think it's important that you shared that experience, where so many would have been ashamed and hidden it. It shows how easy a mistake can be, and that it can happen to any of us with a moment's complacency. An important lesson for you and reminder for us as well.

[@kerrywheeler6720]

I was so excited to see this video. I watch you guys while i work and love your channel but when i found out you were going to Roaring River i was super excited as i live in Springfield just an hour or two north of Cassvlle and in 1975 thru 78 i went to Camp RenewAll there (catholic summer camp) at Camp Smokey and my daughter went there as well starting in 2012 so it was neat to see...keep doing your thing guys!!❤

[@Mikey.M.V.P.1]

I'm so ready for this Epic video & thanks for all your great content ! Gus & Woody & Mike bloody awesome

[@nlsqlcom]

Gus, thank you for sharing this accident and thanks God you alive. You just did this story amazing, it will keep in my brain and will reminds hundreds of divers to keep double checking despite your level of experience

[@MacBuilder]

25:00 Woody: "I'll stay on the loop guys, I'm good" Absolutely a great example of knowing your limits which include trust. Woody didn't know if the CO2 sensor was broken or what so back onto his own loop, smart thinking! Had to edit this for the end. Gus' acknowledgement of his own limitations and the danger he was in, and what he could have done better, is a great thing to show everyone. Best video of 2022-23 for these reasons.

[@quartkne]

This is so cool, thank you guys so much for sharing! Im not a diver and this is so interesting

[@Shaw0817]

Another great video and love the transparency, just goes to show accidents happen to even the best but Gus saved himself through training and safety…. Y’all rock!

[@Biodoc100]

Wow, Gus, So glad things turned out right in the end. Also, thank you for sharing! Some really important reminders for divers of all levels!

[@csih2119]

Cave exploration probably is the most extreme thing you can do diving, you have my respect

[@tylersells8655]

Brother Gus, way to go man! Glad to have you safe. Hit REALLY hard when you said " if i just went to my bailout ".. so wild. you LEARNED so much from this. Great video and critique of perhaps one of the most stressful moments youve had in the water

[@lindaarchinal9008]

You all rock -I’m living my diving life vicariously through you, you make me laugh and stop my heart. Stay safe! Thank you for this!

[@dan1984oz]

complancey will bring even the most seasoned of experts. A routine helps with completing a process however being complacent is usually the reason an accident occurs.

[@ondilogan1963]

That was Wesome Nd to warm it up with the legend was so endearing. Woody, I can tell is such a sweet person. I was watching an episode of cave adventures with Edd and he mentioned Woody as he talked about several amazing divers and said there was one man that doesn't get the credit he is due and that man is Woody. So if you haven't seen that episode Woody, I thought you'd love to here about it. I can tell you are very tender harder and I would bet your a giver and not a taker. Meaning you'd rather give gifts, help, knowledge, things like that. You'd probably give your last dollar to someone hungry and do without eating if you were starving. Your my favorite on dive talk. I like Gus too but he seems to be more buttoned up way too serious about everytbing!! I mean no harm I'm just saying Woody is more tender hearted. But I have love for ya both. I think your best friends and jive and dive well togdther..I'm digging your channel. I enjoy the reacting but like but I want to see more of your divdx8 ,,,,,,,,PLEASE PLEASE, PLEASE,AND MY OTHER ABSOLUTE FAVORITE 😍 ❤️ IS STORY TIME WITH "THE GOAT" EDD SORENSON!!! SPELLING OF LAST NAME?? Anyway I enjoy enjoy all of your episodes and look forward to each and every one. Keep paying your love forward and continue to stay safe and Gus we do not want you to have another incident like this one Because that was too close for comfort excellent conferred! God-bless and continue to Do what you love and and share your adventures with us we love to see The videos of your diving. God-bless from your biggest fan in Tennessee❣️ ❤️ 💙 💙

[@Mikey.M.V.P.1]

So glad u made it thru gus what a close call u are so lucky man ! your training definitely kicked in

[@davidsanderson7948]

Was this before or after the Eric Hahn incident? I now believe this was filmed before. Eric had the exact same problems (O2 toxicity and narcosis) that Gus had but was not as fortunate.

[@joannagomuko6411]

Wow... I never comment on videos but today is the day I need to. I'm soooo happy that you've made it Gus ❤️

[@brizzy420]

Wow Guss I’m so happy you’re okay!!! That’s terrifying you really could’ve died down there by yourself. Good thing you thought about mike 😂

[@seymoreheiri3688]

1st congrats Woody. 2nd I'm glad you're ok too Gus. That was so scary.

[@brizzy420]

@S C Literally so funny 😂 his priorities were messed up but it ended up saving his life

[@TheRealGrimmfury]

Gus & Woody: Another great video, guys! Woody, congratulations, man, laying line in a virgin area! So thrilled for you! Gus, I'm very happy you're still with us. Wow, that really felt weird to say that, seeing it's only been 9 days since I tried to take my life. Anyways, loved the video and I loved seeing the pre dive briefing too!

[@coalrob]

I’m very happy you’re still with us.

[@ThomasGabrielsen]

Good one guys! I love watching you diving. I think your narced episode was scary, Gus. Don't get me wrong, I'm glad you talked about it, but even though I've never met you in person I would've been devastated if something happened to you guys.

[@simonr.7849]

Man Gus, glad you made it out! You telling it in such a chilled mood, although it was a very critical situiation. Great example for how small routined things can lead to disastrous outcome. Sometimes you have to be the lucky guy. I hope you don't need to be it again.

[@markmcintosh2276]

No joke, I have that “love grows here” sign in my bathroom lol and I live in Colorado. So glad you’re ok Gus and what a interesting dive. You’ve inspired me to get my certification in open water and keep going from there. I’ve dived 4 times but always in other countries and never deeper than 40-50 ft. They didn’t care if you were certified or not which after watching your channel makes me realize just how dangerous that could of been. Lol. Funny story, my first dive the “instructor” in Mexico said “take deep breaths like smoking hashish (aka weed in a different form) lol. I was like 16 years old I think lol cracked me up.

[@joeklepac]

Can I just say how much I appreciate the production quality of your videos? So many videos have the worst audio quality that it drives me insane. You guys put out a phenomenal product and it’s greatly appreciated as a viewer.

[@acemannw]

Yikes that’s scary Gus I’m glad you’re still with us I need to get knocked out of your mind

[@EJFXxx]

habitat needs a braided rug and rocking chair

[@TheRealTomLauda]

That was freaking awesome ! The exploration part must have been wild. Like Gus has said, i'm sure the Dive Talk focus on security helped him getting out of that situation safely. I hope you'll do more videos like this one, from the briefing to the exit, it was fascinating to watch (loved the briefing part. Seeing how a dive like this is planned was very interesting).

[@BentBoysDiving]

Glad you made it out alright Gus. Just goes to show how important pre-dive checks and clearly labeling tank mixes are. Also shows how quickly things can go sideways in a cave. People don’t get it: Split. Second.

[@timverkoyen8742]

"Parked" this video since it was so long. Glad you posted it. Very awesome and scary at the same time. Learnt so much!

[@generaliserad]

wow, i love reality checks, honesty and humility. 5 stars, have my upvote

[@kurtzepausekurtzepause1695]

Question: should an error like the one Gus made not be caught by a buddy check before entering the water?

[@DIVETALK]

No. Your buddy doesn’t check every little thing, we are progressional divers and own this part of the process, it was 100% my fault.

[@samiamisme]

Congrats to Woody on his virgin exploration. Do you have a guideline that the anchors for the new line are to be placed every so many feet, if possible? I commend everyone on your ability to get into tight quarters, and all the rest you do. I've always wanted to dive but I don't think I'd ever have the internal fortitude to cave dive. I hate to admit that to myself because I'm pretty good at taking risks and I love being under water, but the potential for being trapped freaks me out. However, it's such a privilege to watch y'all dive and to see how in depth preparations go. I had no idea. I thought you just jump in and go. There's so much to it. It's like Science meets Cousteau. 🥰

[@johnbruce2868]

Real exploration with unique, footage. I'd be just fascinated to see some cave surveying. How is it done, by levelling and chain offset or do you have some fancy technology? I'll never go cave diving, so thanks very much for showing us how its done. Great stuff. Literally, wonderful!

[@johnbruce2868]

p.s. It's that easy to make a mistake. Thank God you're safe, Gus.

[@viliphied]

They have a video from a while back “divers react to how underwater caves are mapped” that is fascinating

[@xw1ngnutsx952]

Excellent film. Thankyou. Very glad the incident turned out as it did Gus. Superb breakdown of what happened. Much love.

[@findthecheese3692]

At 38:05 Woody makes a comment about Gus after having run a 1.7 for a period of time. “It doesn’t linger, once you lower your PPO2 you’re done… (in the clear). Is this true? Does the risk of convulsion not linger like hypercapnia? I know when Dr. Eversole has been on the show before he says hypercapnia will still linger for minutes even after you bail out meaning you’re still in a very vulnerable position. I only ask because you guys do a great job of always fact checking and I’m curious for my own safety how these risks affect divers.

[@TheRealKurt051]

I’m glad your ok Gus I can’t believe you went to 180 on air, you had proper training and reactions it shows how much of a great diver you are. Not anybody can make it out that situation

[@anthonylacy4064]

Those tents are awesome!!! Chill and deco. Very nice! 🤙🏼🤙🏼🍻

[@anthonylacy4064]

Holy moses Gus!! Dang man. Wooooowie. Glad you have a sturdy focused mind or like Woody said we'd unfortunately have a new co-host. Hot dignity brother. ✋ High five for keeping it together. Most loose track and drift off.

[@lambo_drives]

That is super cool; nice work Gus and Woody!!

[@agaldamez3905]

Glad to hear that Gus is ok. Close call. Thank you for sharing. Best wishes to the entire Kiss team.

[@AntonNidhoggr]

Wow, I wasn’t expecting such dramatic turn of events. Glad you’re ok. I remember reading about one of the Cousteau team divers who was actually able to go over 100m on air before unfortunately dying (it happened in 40s). I guess it just builds over time. You could easily go deeper until it would be too late. It’s so good you checked for your buddy and decided to turn back. P.s. When people are drunk they often “go on autopilot” so to speak. I guess the training was that autopilot which helped you to return.

[@SM-McKraken]

Okay. That was easily my favorite DT opener! LOL Gus... well done, Sir!! 😆 o7

[@zdkile7x]

Love Roaring River, go fishing there every year. I heard someone died in the cave diving. Any plan to do a reaction on that?

[@stefanw1686]

Am I the only one curious on the math of the dil flush, at 208 it should have produced a 1.5, especially after doing 2 flushes? My guess is you were actually at the restriction at 225 to achieve those numbers of 1.6,1.7

[@andrewcopeland7413]

So close to me. I even seen arkansas tags :) glad you made it out safe Gus

[@amandalouise9046]

Gus so glad your ok!

LOL at the cable laying music!!

[@GingerNinja1]

@Dive Talk This was awesome!!! Like I said on the last video the cave birthed Woody out of that vertical restriction 😂 but out popped a brand spanking new cave EXPLORER! Whoo Hoo! 🎉 Congrats Woody! So glad you didn't loose your teeth! 😁 & bc they didn't know exactly how deep it was glad you didn't drop that reel!! I love it when y'all do a "series," they're my favorite plus y'all always keep us laughing! Love it. Idk about removing my tank/lifeline & hanging it outside the habitat in a cave where the depths are 600 ft + What do you do if your tanks falls down into the abyss! 😳 Unless y'all mean the "extra tanks?" Must be bc Woody said he put his loop back in his mouth. Gus I am so glad you're ok. How scary. No one is perfect like y'all always say. That's how we learn is thru our mistakes. Y'all should put a photo of the team in there along with Ed bc y'all created the habitats & explored new cave! Gus.... I don't think I've seen your official 1st cave exploration unless it was the series on the Mexican Cenote? That series was AMAZING too! Great job guys so proud of y'all! Our newest generation of explorers!! Pretty cool title to have!

[@jpmcmahon5755]

What a spectacular insight into what it takes to put a cave exploration together. Thank you guys for all your hard work and Gus, I’m glad that you can still do long division. Love to you all

Thank you for posting this series. I go fly fishing here all the time and it's where my dad learned to fly fish and where he taught me. I've always wondered what the inside could possibly look like. Now I know. Now I just wonder just how deep it really goes and where. So interesting.

Glad you didn’t die Gus! But it did make a great story. Learning from mistakes just makes you better at your craft. Awesome video! Should be required viewing for caving diving training.

@divetalk What makes your channel so fun and interesting is both of you. Its your personalities. You are both good honest men, with good character. That matters, and it shows in the videos. Great stuff, Have a good weekend everyone.

Thank God your training helped you stay alive and able to dive another day awesome dive y'all did can't wait to see more dives

I'm not interested in cave diving at all but I enjoy these videos like is my last day on Earth . What a pleasure to watch this thing .

I'm glad Gus made it out ok, I'm happy that he shared the experience with us.

Amazing! Congrats Woody, and I'm so glad you're alright Gus. Can't wait to see you in the next one!

[@MrPink-]

Awesome video. I'm not a diver but a total geek and love the amount of info you guys share. A lot of knowledge. And im sure to divers this is a goldmine of useful info. Gus love hearing your about your issue, no shame in talking about it and thats the way to go, we all learn from it and a next step is reached. Cheers guys, all the best.

Gus, very happy that you are able to tell this story. Stay safe out there, folks!

[@marenzimmermann4693]

It's so humbling to see how much work and effort goes into such explorations. And to see you guys (who are professionals!) so in awe of it is so inspiring. (And glad you are okay, Gus!) Much love from Germany!

[@mikemanjo2458]

Glad you’re OK, Gus. ❤️

[@stevedenruyter4902]

Dude 😳 Gus you escaped the grim reaper bro 😳 You’ve learned a big lesson never assuming it’s ok. I have to agree being part of something like this is exiting that could be a reason. Glad you’re ok, awesome video and congrats to the team

[@tetsaiga005]

I've noticed a few things with new gear or less used gear. Gus's using the Sidewinder mistaking the gas sides when you normally use the Spirit. Woody having issues with his new battery pack for his drysuit heater in the mine dive and getting caught on the surface exit and Roaring River. The adjustable d-ring allowing the bottle to slide down further. Most of these seem like they're not a big deal but when you're on an advanced cave dive in a completely new environment, can be life threatening with unnecessary task loading or causing problems at depth. Glad to see you both made it out safely. We've seen in your videos (Pearse Resurgence separation at 700ft) that things can go south in a matter of seconds. You guys are so good with examining your own mistakes and being humble though. Keep up the good work!

[@zaraspook0]

Glad it all went well in the end and again its awesome to see some real exploration in my local area!

[@fractal4284]

You need to get a tablet playing dive talk episodes and keep it in the habitat on a loop playing videos of dive talk 😂

[@mbrown5533]

Hey Woody and Gus, Love your show and I'm grateful you're ok Gus! I'm saddened by the news about Eric and my thoughts are with his family and friends! Would you please post an episode detailing Gus's incident? There seem to be unanswered questions and much we all could learn from this? Specifically, what happened between 100' (where Gus is fine) and 160' (where Gus is too narced to bail out and turn the dive)? When you guys cross each other at 80'-100', was Gus's po2 at a reasonably normal level for this point in the dive? What was the o2 % of the deep gas? At some point before reaching 160', Gus states he's noticing his rapidly increasing po2; when did this happen and what prevented Gus from halting and evaluating as soon as he was aware of the unusually rapid rise in po2? Presumably narcosis. Are some divers aware when they are beginning to experience narcosis? Does narcosis happen gradually or is it something that sneaks up on you? Additionally, how did Gus know what his deco obligation was? How much deco did he do? Should he have breathed 100% o2 at the surface? I'm not yet a tech diver so please forgive me if some of my questions don't fit the situation. Also, I'm not trying to throw stones; I just want to learn as much as possible from the experience and anything Gus can recall would be helpful. Thanks and keep up the great work!
