I think a lot of these guys get a few minutes dose of pure oxygen before submerging, so it’s not totally unassisted.
Still, 29 minutes is crazy impressive.

That is what I read about another record setter.

Pure O2 is toxic below 66 ft and very dangerous below 33ft.
It might be Nitrox which is 36% O2 which is safe to 120ft.
