Feeling bit of an idiot, I think I left my brain cell behind. Yesterday at the airport I took my dive knife in hand luggage wich was duely confiscated.
Anyway this mornings dive my wife noticed a stream of small 'champagne' bubbles coming from the high pressure hose. So after lunch I had the hose replaced, the technician asked when was the last time I had it serviced. Well, I've had it for 7 years, I had the battery replaced twice, changed first stages, regs and all hoses BUT.... coming to think of it never had the Cobra serviced - hose or connecting O-rings. the battery changes were just that. The tech should me the state of the rings and didn't look all that good.
So, as well as having the regs serviced it's worthwhile doing the SPG as well, including air intergrated computers.
