According to Guillaume Nery himself, this is fake.
I googled “deepest free drive”.

According to my internet search Herbert Nitsch holds the world record at over 800’. He also held the previous record.
I guess he can hold his breath for over 4 minutes.
Also, apparently, many people DIE attempting to break these records. Half the articles that came up in my search were about the deaths of people trying to dive deeper.
Sorry, Mea Culpa.
He can hold his breath for 9 MINUTES. Can you say HOILY CRAP!
“Herbert can hold his breath for more than 9 minutes and has set 32 world records in all of the 8 recognized disciplines – unrivaled achievements in the freediving history.”
