lol, if the cylinder is at 220bar hot then when it's cold it'll be.......less. That's good enough for me.

All of which is completely pointless as you don't know the temperature of the gas inside the cylinder.

So is it worth 'overfilling' tanks for colder dives as you will 'lose' gas due to the water temp.

But when the gas gets into your lungs it will be at body temperature so 'a lung-full' is the same unit regardless of cylinder temperature.

Just put the cylinders into the freezer before getting them filled and it will end up at a reasonable temp.





Thanks not entirely serious.
