Britney Spearz, Hi, how do you know you now have 20 Bar?, do you have a pressure guage?. Dont take the info from "Seacsub" as Gosple, I have a 130, & they told me to pump it to around 540 pump's for a pressure of 20 bar,(I had to contact them as the manual didn't even list the gun) Rubbish!. It took 1000 pump's to bring it to 20Bar (This is acurate as I used a pressure guage) I told them this & they said, "Oh, the figure we gave you was just a "round about" figure". I strongly suspect that they quote well on the conservative side, to make sure that poeple dont "over pressurise" their gun's. Incidentaly, I put in 1200 pump's to take it to 23 Bar unloaded, when loaded, the pressure increases to 24 Bar @ half power, & 26 Bar @ full power. Hope this info help's, ...... safe diveing...Geoff. PS. Remember, this info is for a Seacsub ASSO 130 only!, also I do not reccomend you pressurise it over this, as this pressure still give's you a "Safety margin" of 4 to 5 bar ( your gun, any ASSO, will fail at around 31 Bar) to take account of increased pressure, caused by the heat of the sun. or even a hot enviroment. One more comment, my pump was working properly, with no leak's.
