Thanks for that Rob, I didn't need the lesson but found that very funny anyway, credit to the guys who wrote it, probably with crayon
I may take the plunge later on next year if funds allow, I was very tempted earlier this year by the Azimuth SCR by the simplicity and its use of common parts, but for now I'll have to make do with a try dive next time Andy (Dales divers) arranges one.
Merry xmas everyone.
