The scuba divers are there so if something goes wrong they can save him!

[siber66]

which equalisation method he is using?

[Aidan Sharples]

Unless of course the container is itself less dense than the fluid it is immersed in.

if i defeat panic attack. first of all i'm gonna learn scuba diving and dive at the red sea. it's my most unreachble dream..

[sevenrats]

I was thinking that after the third pull and kick on the way down I would be thinking about breathing again.

[sevenrats]

Wow. Correct information in Youtube comments. Unprecedented!

[sevenrats]

Agreed. If you can do that, you can do anything.

[jlc012]

Now thats one badass mother fucker right there.

thekiller0673 is correct about the dive reflex: as you descend your heart slows and your spleen releases more blood. The Arch is about 180 feet down, so William's MDR (the diving reflex) would really be kicking in. Another reason for the extra tanks is that that the scuba divers are probably breathing mixed gas, especially if they are trying to: 1) avoid nitrogen narcosis, and 2) have reserves for decompression.
