PADI Advanced Open Water Diver course, one will be the Underwater Navigation dive and another the Deep dive (between 18 - 30 metres). You and your instructor will choose the other 3 from 15 different Adventure Dives. You might try your hand at digital underwater photography, wreck diving, night diving or peak performance buoyancy.
You were sent a warning about spamming the main BSAC forums, now you're here.
Just an attempt to jump up the Google listings.
To the mods, my suggestion is delete this thread.
