So filled to ~200 BAR these tanks hold about 85cuft of air. And filled to 232 BAR they hold almost 100cuft. Wow! Those are great tanks! I am short, so loved diving them. They trimmed out perfectly for me. Are they available in the US? I don't think I've ever seen one before.

Yeah, sounds like a dumpy 12 as someone else said. These tanks have a diameter of 204mm which is the same as a standard European 15 litre cylinder, so easy to double up and we do it regularly.

The ones made by Heiser were a little heavier, but Faber also makes them and they are pretty much the same as a standard long 12 litre.
