Further to the last TDI NITROX posting, I was wondering exactly what knowledge the advanced course "gets" you and what are its practical applications?
The main rason I ask is for the issue that I mentioned previously of planning for redundancy for the kind of diving I am likely to be doing in the near to medium future. Aditionally, for example, how big a twinset should I realistically have to get to last me for the forseeable future?
I'm not planning to find the lost city of Atlantis or anything, so I doubt that twin 18s and four stage bottles are quite for me!! (was thinking along the lines of twin 7s or 10s)
Ta very much
