Santa gave me a fire-retardent suit for Xmas so I thought I might give it a whirl.
I have been thinking of using the above tanks.
81.4mm diametre 274mm long (no valve) 0.9l and 207 bar rated.(6 CFt)
That isn't alot of gas 186 litres (or 207 litres @ 230 bar

)
Their use would be for recreational dives 30m's and up. To make the rig lighter and narrower. ( I would put them underneath instead of on the sides.)
I would always dive them with adeqwuate bailout.
Anyone using something similar?
How are you 2 litre boys and girls finding them.?
