You will get more total shots out of your dive cylinder if you fill when you have to, not keep topping up unnecessarily. Each fill loses the air in the hose and gauge. In the case of the S200 with its small cylinder, the void volume of the hose etc is quite a significant part of the whole. So this is important with S200s in particular.

Thanks for the info.

What I generally do is by going on what I've heard & been told is; fill it up to 190Bar, fire between 40 -45 shots then refill.

I got my 12 lt bottle filled earlier today, so now I can use this as a base & compare. Which means I should get about 1800 shots , not bad when it cost me £2.75 to fill the bottle.
