Wow. A sad trifecta – narced, ox-toxed and bent in one dive

Edit: his gas density at the bottom was likely enough to lead to a CO2 hit, too

Curious whether this ‘dive plan’ was shared with anyone prior to the dive

And what training he received that made him think that this would be safe?

 

[Wibble]

A deliberate and successful suicide attempt.

The MOD of 21% at 1.4PPO2 is 57m/190ft. ALL technical divers know that.

His wish came true. Just as certain as if he tried to stick his head into a crocodile's mouth.

According to the original article, he want break dive depth world record, "U" type air deep diving (
maximize bottom time ) is him trainning method to bulid resistance of nitrogen and oxygen.

The world record is: 509ft/155.143m- Dan Manion, 1994

... is him trainning method to bulid resistance of nitrogen and oxygen.

I don't think that's a thing.

509 feet on air? Or am I misunderstanding?

509 feet on air? Or am I misunderstanding?

A quick google search says that yes, Daniel Manion did a record dive to that depth on air, and that his record was broken in 1999. Who has the record now, and how deep it is, I don't know (nor do I care).

It would imo be for the best if people stopped going for these ridiculous records, but it will unfortunately keep happening for as long as some people have egos larger than their brains.

Its real, this guy passed away on 2018, SB link: Dr. Daniel Joseph Manion, M.D.

Yes, both scuba and freediving, depth have no meaning, most beautiful view is above the ow limit.
