so many tanks for the diver!!!

[roakey]

I have a question:how long can he dive with so many tanks (about 100 feet)

There was some discussion about this picture about a year ago, and it was decided that it was staged (in other words a joke).

But to take a guess at your question, looks to me like 10 AL80s, so that's 800cf. At 100ft (4 ATA) with an SCR of .5cf/min that's 2cf/min, divided into 800cf is 400 minutes.

What about your previous venture, moisture enhanced land in Florida?

only 400 MIN?

Less actually. An AL80 only holds 77.4cf, so that's only 774cf of air. As Roak said, 100ft (4 ATA) with an SCR of .5cf/min that's 2cf/min... 774/2 = 387 minutes. Or 6 hours 27 minutes.

Valuable dive planning lesson in that for all of us... somewhere.

THE FINGER. Didn't you see the severed Finger... Keep in the game, man.

I swear, divers have the attention span of a 4 year old.

How would you like for me to respond to this?

You're welcome to disagree with the cylinder size, the number of cylinders or the SCR, but the calculations given those numbers are immutable.
