Question How many times can I fill a steel 72 off a pair of 130s?

I also forgot how heavy those monsters are, and how someone used them doubled I will never know. It will be interesting trying to dive them one of these days.

I used to have a couple of them. Quite heavy. I’m with you, can’t really see doing doubles with them.

I dove them for many years. Got rid of them as they were more hassle than the other 7 1/4” diameter tanks. Picked up a pair of 120s instead. Much prefer them or the 100s, depending on who I’m diving with.

The guy I bought them from had them configured as doubles with the bracket and manifold. I got a screaming deal on the set, but still haven't used them. My steel 72 just works for most things so far, but sooner or later I will need more gas and one far single seems easier than two smallish tanks.
