News reports and that of friends/relatives are not always factual. Case in point the assertion by the fiancee that safety was of utmost importance.
If that was the equipment, safety wasn't all that important, regardless of what anybody told her.
The back gas looks like double 98's and one "deco" tank looks like an 80, and the other I'm not sure. Maybe another 98. I believe someone mentioned that the deco gas was left at a staging location, and wasn't carried.
If the tanks were full, each diver had about 196 cubic feet of back gas.
A 210' dive (I believe I saw that figure) for 20 minutes, requires about 203 CuFt of gas, which is more than 10 CuFt more than they were carrying, since you can't breathe the tank down to "zero".
It leaves nothing available for emergencies or failures, making any lost-gas or "used too much gas" problems 100% fatal to both divers.
