There's actually been a push by some to completely do away with the isolator valve because in a lot of OOG situations the diver has been found with one tank still with gas. They either rolled it the wrong way or forgot or whatever.I also have not personally seen or heard of any widespread manifold failures to make me think they are inherently more failure-prone than diving without a manifold. The pros/cons just don't line up for me - either dive manifolded doubles or dive sidemount if you want independent tanks.
We use to call those twins. If they are connected, they are doubles.I’ve seen the term “independent doubles” used to describe this configuration.
My twin tank (and that of my wife) are manifolded, but they do not have an isolator exactly for this reason. I always want to be sure that both regs have access to all of my gas.There's actually been a push by some to completely do away with the isolator valve because in a lot of OOG situations the diver has been found with one tank still with gas.

That's always in the back of my mind when I splash. Always check my isolator
Well that pulled up what I was looking for thank you!I’ve seen the term “independent doubles” used to describe this configuration.
