Eagle's Nest Cave Mapping, Florida, 1990, Deep Breathing Systems 

This is youtube gold. And very few have yet to find it!

I saw this for the first time today and it was an odd experience. I was a member of a small group of divers who explored Eagle's Nest many times in 1967-68, about the same time Exley, et al, were. Two of our group, Frank Martz and Randy Hylton, either knew or had met him. My memory is not clear since it was so long ago. It's an eerie experience to see those familiar scenes so many years later. It brings back the rush and fascination we experienced every time we were there. I used to love to turn off my light and hold my breath just to experience the total darkness and silence. We were young and dumb...did our diving on straight air after filling tanks at Weeki Wachee. Mixes were just coming into use; most of us couldn't even afford wetsuits, much less that sort of exotica. I never went deeper than 240' because it scared the hell out of me and I got nitrogen narcosis. I volunteered to be the safety guy at the bottom of debris cone at about 150'. Co-divers did go to 300'. Sadly, on Father's Day 1968, my good friend, Melville (Billy) Palmer Eslin, drowned there while on a deep dive with Martz. Similar to the diver you lost, Frank said he looked back to check on Billy and he was unconscious. He was only 21. I have often wanted to return to Eagle's Nest, certainly not to dive but just to pay tribute to Billy as well as the others who have died there. I haven't been able to do that yet. I was hoping some sort of acknowledgement of the lost divers would be shown at the end of the film.

Mr. Ballen had a story on Eagles Nest. But this video is way more educating than what i had heard.

DIVE TALK needs to see this 😍

Man the 90s were some golden years imo

just imagine diving on that cave with old school gears

pitch dark and surrounded by darkness is truly scary and uncomfortable, when i got swimming i stay where i can see the surface, but dame these dudes are brave and have massive cajones!!!

Man this soundtrack is lit

Thank you guy for a great vid and thanks to Mr Ballen for his well descriptive stories that brought me here.

Those 90's electronic drum fills @8:11 are amazing. Its not every day I go delve into diving videos and find something that delivers my scuba nerd-out while also giving me that childhood nostalgia of 90's television. Great documentary. I hope to cave dive in Florida someday!

Wow I was there back in those days it’s wild to see it look like that again with no roads or docks.

This is fantastic. Priceless cave footage!

Very cool!! Thanks for posting!

This deserves much more views!!!!

By today's standards, the equipment in this video is archaic. Having said that, these folks are boldly going...

Absolute madness! enjoyed it!

Best cave exploration video ever

Awesome video Chris !!! I hope all is well with you !!

Perfect documentary! Classic quality that more should see. Bless those who lost their lives to exploring for fun, educational reasons and saving lives! ❣️💯😃👍💯

Haha those old DPV’s were a nightmare.

This is exploration at its best, thorough with careful preparations and in-depth risk assessment. What a fascinating place. I was wondering if there was any sign of life, either flora or fauna, at those depths. Remarkable achievement, going truly where no man has ever gone before, the thrill of it. Thank you for your informative video.

I like the music they chose 👍🏻 May the #BraveDiver #RIP 😞

Omg! The sound track to my Jr high life!

Dive talk needs this one

This is awesome

Great narrative !! E the dives

Lord this is an old film.

I have been diving there and it’s beautiful down there.

Imagine drowning in a cave with that soundtrack though.

The track starting at 6:56 goes hard.

Think, in a million years someone will probably hike this gave wondering, "I wonder how this was made?"

Pffffft!!! 295’ air dives! Guys were nuts back then! But it’s true, “you don’t know what you don’t know.” 🤷🏼‍♂️

The music in this documentary slaps

Never understood the pressure in caves. There is so much less water in a cave than the ocean, often it is not all directly above, so why is pressure at the same depths the same as the ocean? I’d be curious to know

The guys &girls that do this fairplay massive balls 😀

That cave is so dark it’s almost pointless to enter

i think im gonna bring my son here one day

Interesting video. The backround music sounds like bad porn music thou. Lol.

*you'd think everyone who swam that died, from all the internet videos*

Are the stage bottles on the bag ABO 200 cubic ft. What does the 1st stage reg look like and how do you adapt to that valve style

Nơi nào bình yên công việc thuận lợi thì ở thôi Lộc huynh ơi. Miễn là không quên cội nguồn gốc rễ là được. Chúc gia đình a gặp nhiều may mắn- bình an và hạnh phúc!!!!

I’m surprised Sheck Exley wasn’t on this dive.

Back around 1990, I purchased some beautiful large-format cave map prints. They are signed by some one named "Eric" something, perhaps Hutcheson. I still have those prints. Can you tell me more about them? The one of Eagle's Nest is particularly beautiful. They are "Blue Prints".

Lots of people died in this cave.

Where did y’all go eat at?

Surely the safest way to map & explore underground water caves is to use unmanned underwater drones with CCTV like those used for deep ocean exploration as if they can get to the bottom of the ocean ( which is many times deeper than any cave ) they could be used in caves with no trouble at all as such devices already exist & are used by water companies for sewer mapping & exploration & the use of unmanned remote controlled devices to explore these caves is much safer & eliminates all the dangers & are such devices actually used for cave exploration?

Man....i could never do this and enjoy it. I'd have nervous breakdown. Kudos. Not for me

Narrator sounds suspiciously like instruction video..23 min mark narrator returns, instruction diving confirmed.

Oh hell yeah. Those shorts are bitchin!!

What about the Sinoya Cave in Zimbabwe????

I wonder if anyone is working on a GPS system for cave diving. Not sure if possible with the your in acave thing

4:15 - 4:27 "Simply enough..." Yeah.. uh.. totally simple...

Why dont they dent a motorized robit down there?

Gotta be clued up on relevant knowledge/skills & on ya game + a little bit nuts(in a good way) or brave or both to be doing deep cave diving.....

Did Brent die?

I'm surprise divers dont swim into a gator den mapping these caves or at least they don't talk about it. I'll like to here what happen when they do

No...just no way.

Looking for gold nuggets.

Rubbish like the elevator music
