AZi, its due for some TLC and new o rings through out (and new cells now

). Luckily for Brett he got a mouth full at a point where he could surface, but yes he was knocked about badly. The SK is bad in that aspect, that you are unlikely to get any warning. The Azi small hoses means you feel the change in resistance when the hose gets filled up. Gave me just a hint to get ready.
