How did Cousteau's team maintain bouyancy - see attached link

Gilldiver,

They also ran quad titanium 50's at 5000 psi, which is almost equivalent to 3 hp 100s

JC did, and I can only wounder at how negative they must have been at the start of a dive.

But, have you seen any lately?

As has been posted, proper weighting and good breathing techniques were sufficient for the diving I did between 1961 and 1989. It wasn't until the latter year that I wore a BCD... it was required equipment by the Cousteau team I was diving with.

Funny thing is that the BCD kept auto-inflating on me as I descended, so I bobbed back to the surface. At first the DM didn't believe me until she observed it first hand. She asked "What are we going to do?" I said I'd just disconnect it and dive like I had for the previous 29 years!

I'm glad I have a BCD now and don't dive without it. It allows me to be sloppy with my weighting although I still use good breathing technique to fine tune my buoyancy.

As for the three tank packs, my recollection of them is that they would not hold air for long if it got trapped inside.

... and a much more active swimming style to hold depth.

Creature From the Black Lagoon was on recently and I was surprised to see back in the 50's just how hard the the guy was finning underwater. Active swimming style might be an understatement!
