I think you all need to seriously consider learning to be a buddy. "I don't care" should never be part of the buddy arrangement.
Edit.....I'll give you the benefit of the doubt and say this was a language barrier....lost in translation. BUT, someone, his buddy and the DM/Captain should have been looking for him as soon as they realized he was missing. In fact, the Buddy should not have been able to separate and surface without knowing where the other diver was going (i.e. depth, direction etc.).[/QUOTE]
Really? I have not done many drift dives in less than 10 ft visibility, along vertical walls, in strong currents...in fact, I don't recall any dives that fit that description, but it would be extremely easy to get separated and once that occurs, there is not a whole lot more that can be done except wait on the surface and look for bubbles or soemthing... Come on over 330 feet deep .. bad vis, strong current, down currents... what exactly is the operator to do once separation occurs?.
