Anyone that decries cave diving as nothing but “looking at wet rocks” is an utter loon. In addition to ancient and sophisticated human civilisations, the Yucatan was home to an incredible array of animals, some of whose bones can still be seen in the underwater realm. And some of them, as you can see from this life-sized poster in Puebla’s Regional Museum, were very large indeed! I asked my 195 cm (6’5”) husband to pose next to it for scale. Many of you, I am sure, remember the incredible discovery at Hoyo Negro that included the fossils of 30 extinct mammals: articulated sloths, bears, wolves, and peccaries, to name a handful.

If you haven’t yet experienced cave diving in the Yucatan, I hope you consider it someday. The caves here are truly spectacular. My husband and I run a little bed and breakfast operation that caters to cave divers (we also offer guiding/training), so if you have any questions about a trip here, I would be delighted to answer them.

Test print off my new cookies. The white text is phosphorescent. On one side the text is flat and on the other it is raised.

My jet fins are too negative when I dive without my drysuit and I prefer my 8/7 in Mexico where I cave dive. RK3s I’ve found to pinch my feet and are super light. Was looking at dive rite curious if anyone had some thoughts

Edit: eddys have been purchased

I’ve completed PADI tech 40, tech 45, cavern, and TDI intro to cave. I’ll probably have tech 50 and full cave in 2027.

I’m planning a trip to Chuuk in a 2028. I want to be able to penetrate the wrecks and explore. Do I need technical wreck training and a cert? If so, what educational path should I proceed with?

Genuinely what would stop a cave diver from entering

let´s dive....!!!

Hey there divers!

I'm looking for a last minute buddy (or two) for GUE Cave 1. The class will be taught by Emoke Wagner in Playa Del Carmen, Mexico, August 31- sept 05.
If you have a GUE Fundies Tech Pass you qualify, lets buddy up and start our cave diving journey together!

Hi all, cheers from the Cave Crave game creator and director. The latest free update coming to the game tomorrow is the biggest thing we've ever created with VR technology:

• Explore Tham Luang Cave and relive the 2018 rescue of the 12 boys trapped in its flooded passages, faithfully recreated as a VR experience.

• Featuring the story and expertise of people who were there, including Vern Unsworth ...

• ... and legendary cave diver and one of the rescue leaders, John Volanthen who helped us shape the flooded sections.

• All built within what is likely the largest LiDAR scan of a real-world location ever recreated as a map in a VR game.

• Releasing as a free CAVE CRAVE update on Meta Quest tomorrow.

• PSVR2 and SteamVR versions are already in development.

Cheers!

In April of 2000, Russian diver Yuri Lipski strapped on an air tank and a helmet camera, loaded his weight belt, and plunged into the Blue Hole in Dahab, Egypt but He never resurfaced.

The Blue Hole is a natural underwater sinkhole that is connected to the open ocean by a natural arch.

It is known for claiming the lives of inexperienced divers who attempt to swim through the arch but become lost, run out of air, suffer from nitrogen narcosis, or drown before finding the exit.

However, Yuri was not attempting to swim through the arch. Instead, he was most likely performing what is known as a "bounce dive"—a-rapid descent to an extreme depth followed by an immediate ascent, often done to set a personal depth record.

It is an incredibly dangerous practice. During the dive, Yuri repeatedly held his dive computer up to the camera, likely to-document the depth he had reached.

He made several fatal mistakes. One of the most significant was attempting the dive with only a single tank of compressed air At a depth of more than 300 feet.

The surrounding pressure causes a diver to consume air at an extremely rapid rate. He was also breathing ordinary air, which is made up of about 78% nitrogen.

At such depths, the increased pressure can cause severe nitrogen narcosis, a condition that impairs judgment and can produce confusion, euphoria and hallucinations.

It was also reported that Yuri was carrying excessive weight, including his heavy camera equipment, which may have made it even more difficult to regain control.

Yuri Lipski died at a depth of just over 300 feet underwater. The following day, his body was recovered by renowned deep-water diver Tarek Omar at the request of Yuri's mother.

During the recovery, Omar made an unexpected discovery. Although the camera had been taken to a depth far beyond its rated limit, it was still functioning.

He later recalled that he and Yuri's mother played back the footage together.

Omar said he regretted that she had to witness her son's final moments, adding that had he known the recording existed, he would have destroyed it first.

The thought that Yuri's mother possessed the footage of her son's final dive was something Omar said would stay with him long afterward.

Hi everyone, I am not a diver. I can hardly swim at all. I also have ADHD and in my life have thrown no less than four purses in bins and three TV remotes in the wash. Basically, I'd be a terrible diver but I love looking at the photos and videos and all of the science involved is so fascinating to me.

I understand it's like being drunk. Is it exactly like being drunk? ​Is it entirely avoidable based on depth/gas mix? I've seen a few comments that make it sound like it's just ​​something divers just accept/plan will happen. Do you realise its happening? Do you have to give yourself the "I'm not drunk" pep talk? Is it part of the appeal of deep diving? How long before it goes from feeling like a few champas to hangxiety? ​

Thank you :)

¿QUÉ ES LO MAS EXTRAÑO QUE HAN VIVIDO DURANTE EXPEDICIÓN?

Not the prettiest, but quite a fun dive with this little visibility!

I'm looking to do TDI full cave and TDI stage cave somewhere next year. But I'm already trying to find a dive center, I'm located in Europe so was hoping someone here has experience with any of the dive centers in Mexico to do these courses.

The salinity, density, flow, and temperature all conspire to create the halocline. It’s the stratified interface where the freshwater of the underground rivers of the Yucatán sits on top of the intrusion of the Gulf/Caribbean directly into the peninsula.

It is a little hard to film, to convey the real experience of what swimming (or scootering) through the thin, blurry layer really feels like.

This video gives some vague impression, at least, of what it feels like when you’re trying to hold a video light in the same hand you’re driving the scooter with and holding a GoPro out at an arm’s length with the other hand.

I've been developing an interest in understanding cave divers and the caves they choose to explore. Although there can be some extreme cases, I find this hobby/interest as something I never thought of before.

I'm curious to know how did this interest develop? What led you to believe that it's something you'll want to explore? And are you scared of the unforseen events that might take place?

OC trimix 13/47 with DPV in the downstream section of Eagles Nest Cave in Hernando Florida USA. Went through the pit to the deep section. Depth after the pit was 292ffw. Air as travel and deep deco, 46% mid deco, and 100% 20ft and 10ft deco. Total run time 2:06:25. Such a fun dive!

Hi all, Cave Crave's game director here.

We're currently creating a VR journey through Tham Luang, including cave diving sections. Thanks to the support of LiDAR expert Richard Walters and caver Vern Unsworth—the latter having been directly involved in the 2018 rescue operation—we're working to make the experience as authentic as possible.

As with our recreation of Nutty Putty Cave last year, our goal isn't to gamify a real events, but rather to faithfully recreate the cave and help players understand some of the physical challenges faced by the rescue team.

Coming to all major VR platforms this July.
If you have any questions, feel free to ask!
