I am also having a tough time wrapping my head around the question.
Consider an alternate question. What do I consider to be an advanced driver?
- Someone who has been driving for 25 years. So from this perspective,
maybe.
- What if this person hasn't been instructed on driving cars in race tracks? With my many years of driving around, he could probably take an SUV to a race track and drive it really fast and not have an accident. Maybe the trained racers will tell him that he is foolish for driving on race track with the wrong equipment with insufficient training. Even the properly trained and equipped teenage racer who has only had a driver's license for a couple of years might consider me foolish. (And he would probably be right.) So from this perspective,
maybe not.
- But even if he had training in racing cars, what if he doesn't have training in driving commercials vehicles - buses, big rigs, whatever. So even if he had both of the above, still
maybe not.
- But even if he had all that training and experience listed above, he still probably would struggle to drive in the streets of Ho Chi Minh city. Ref:
Part 2 of 3D Driving in Ho Chi Minh City, Vietnam - YouTube
A person can tell you what he has been trained to do and what he has experience doing.
- basic training in driving small personal vehicles.
- driving for 25 years.
- driven in sun, rain, sleet, snow and ice.
- clean driving record.
- etc
Similarly, a diver can produce a list of dive training and experience.
However, i think the question of what is an advanced diver (and what is an advanced driver) is too ambiguous. Any answer given, provided that caveats were provided, would probably be a decent answer.
