Nearly done with my first lot of UW torches. To do list: hydraulic tests and final assembly. It's quite clear with assembly, but still have my doubts about hydraulic tests. Mainly it's for recreational scuba, however I'm hell curious, how much it can take. I'm pretty sure, the body will survive 50 bars, not sure about the glass. Well, two of them will have to take 20 bars as it's a matter of time and money when I will descent to 100 metres. To be honnest, is mostly money as gear differs from recreational for such depths.
