I have been reading some very old posts back to 2008/09. One from our old friend "Bottlefish" puzzles me. Stuart mentions that when he did his AOW back in 1999 he was qualified to 40 mts. When Mrs PD did hers in 2003 ( we still had the paperwork) she was told that she was qualified to 40 mts as well. If this is the case when did the AOW depth come up to 30 mts. If it true it was 40 mts when she did her's is she still qualified down to 40 mts. I must admit she has always said that she is really interested in diving to 30 mts let alone 40.
