Hi Gadget,

If I remember right

a J is 47.2 litres so 47.2lt x 200b = 9440 litres.

Of course if I'm wrong I'm sure someone will correct me

around 10,000 if your being approx
in reality there 47 and you don't get 200 bar

Maybe when I was running a dive shop I was always lucky as can't remember getting a single J that had less than 200 bar.
Most were pretty spot on 200 or if I was 'really' lucky occasionally got 205 bar

Luck of the draw I suppose..

Hi Si,

Just be careful if you are talking about the Red Sea, I never used to get 200 bar in a J out there.

Cheers,

Dave.

Cheers dave

I know the egyption idea of 200 bar is more like 150 to 160.

You can also forget the 100% O2. We had 96% + some unknown substances on our last trip in Egypts.
