Best I have ever done is grab sand from the bottom at 80 feet. I can stay at 30' for about a min. when spearfishing.
These guys have reached 600+ feet and over 17 min static. How the hell these people do it I don't know,I takes everything I have and every trick I know to get 1/10 of what some people do. |

Call me an idiot, but how does he sink so quickly (my fat floats me  ) and, really, how long can a person hold their breath anyway?
Awesome video. He is wearing weights. Some can hold their breath for 5-6 min. I think the WR is over ten. Ten minutes holding my breath.....oh wow. I just sat here and held mine for one minute. At the :50 mark I was hurting (inhale, exhale a little every 10-15 seconds) and suppose I could go 1:20 or so if my life depended on it. Ten minutes. wow. |

I've done a bounce dive (with air) off the Bimini Wall down to 318 feet. Straight down and right back up. It was scary yet fun at the same time. I would never do it again.  My ears cry even thinking about that. If you can equalize going down to 33 feet, you can equalize all the way down to 300+. No biggie. |
| I wonder if he has a pocket rebreather or two in his pouch. I dove off the Caymans several times (with air) and right at the walls, the depth goes to 6,000'. First time I dove it I hit 150' without even knowing, except that the alarm went off on my dive computer. The water is so clear that depth perception escapes you. |

It has been a while since I updated my dive gear, but I don't think a pocket rebreather exists. |

Between each scene he would get air from the camera guys alternate mouthpiece. |

I have to take sudafed the night before I dive or I have trouble with my left ear. I haven't gotten below 100 yet. I will next summer though. |

Plug your nose, hold your breath and gently blow until the pressure in your ears equalizes. Your good for another atmosphere.

Some people can just swallow, others can wiggle their jaw, I think most of us, including me, have to close our mouths, pinch our noses and exhale. I do it every few feet. |

As a kid I could hold my breath better than most - still I don't think I ever pushed it over 2:30. I am certified scuba - but preferred skin. That said, my ears did not. Got to the point I was at the doctor after almost every day diving. I think it was a combination of 2 issues, one of which I have learned how to control. The other was getting water in my inner ear, which really sucks. Regardless, I have only skin dived once (honeymoon) in quite a few years. It was vastly disappointing - I chose poorly. I really should have chosen a scuba dive and left the tanks in the boat. videos look neat - but I would never try it. |

Thanks Dan_Gray & DV8 for responses, I'll have to give it a try next summer 
Nothing else like it man. Sometimes I like to drop down to the edge of where I can really see the sun light, and just hover staring up, watching the bubbles. It's a lot easier if you can do it on bottom.

The video may have been shot in a few takes, but it was still done using breath hold or free diving for both the diver and the camera person.
I don't think i saw any SCUBA anywhere in the video and it would have been very easy to see rising up the hole. The divers are also moving to fast up and down it the water for a SCUBA diver to film. When free diving you are not limited by the issues a person breathing compressed air does. You can decend as fast as you like on ether, preety much as fast as you can equalize you ears. It's the going up that becomes a problem. On SCUBA you can go up at around 60' a min. About as fast as your bubbles rise. Most half that to 30' a min. Then there is saftey stops and all sorts of other stuff that limits a SCUBA diver. When you hold your breath these rules don't apply. Have put on two 7mm wet suits before and strapped on like 60 pounds. Let go of the boat and hit the bottom at 60' in about 10 seconds. Drop the weights (on a rope) and ROCKET to the surface. Good fun. Thats how they set the unlimited breath hold depth records. They hold on to a weighted sled and fly down a wire. At whatever depth they get to they grab a depth marker and inflate a lift bag and fly back to the surface. I think the record is well over 600 feet. Rebreathers or breathing off SCUBA was not used in this video, it would have been deadly. |

DG84: Okay, I just did. Doc: I didn't see it, do it again. DG84: There. Doc: Nope, do it again DG84: Did it again, I swear, my ears are popping. Doc: I still don't see it. DG84: ***Holds nose, closes eyes, and blows as hard as I can.*** Doc: There ya go. DG84: Yeah, I did that the first time. |

I bet this guy clanks when he walks. Something that I think everyone is missing: No bubbles from the cameraman on the way down Credits mention cameraman is a woman freediver as well No bubbles just means the camera person is using a rebreather, which doesn't vent air, it scrubs off the co2 and recharges it from an o2 tank. The mouthpiece is usually bulky since it has an incoming and outgoing line. |
