Advanced diving... I'm sure I've seen this thread here before. I've been certified for about a year and a half now and I still have less than 25 dives, unfortunately. Next year I'll probably get that many in a single week but so far that's what I have. I have been in cold, dark conditions, I've been in "infinite" visibility with warm water, I've done drifts and been in mild currents. I was comfortable with all of them. I've been deeper than my "recommended" depth and I was comfortable with that. I've done night dives, boat dives, and shore dives and been comfortable with them all. I've dealt with a blown wing underwater, dead lights, minor free-flows, and blown o-rings at the surface (but in the water). I was comfortable with all of that.
Combinations of these things would require more experience, I think, but aren't even what I consider advanced. It's still basic diving- strap on a tank, grab some lead and get in the water, without the need for significant planning (though planning is good and appropriate). When conditions start to "multiply" the "difficulty factors" such as current at night or heavy currents in a new place, I would consider that something I should take carefully but does not require further training (other than experience). Even depths down to rec "limits" I wouldn't really stress over but I would take them slowly. I've been to 75 or so and would certainly go deeper without worrying about it much but I can't really get much bottom time out of that at this stage so I don't see the point. If there was a wreck or something that I knew the bottom wasn't deeper than 120-130' I wouldn't worry about it. I know the symptoms of narcosis and I tend to be very conservative about my own body's reactions to things so I'd dive it and make sure my buddy and I planned accordingly and do the dive.
Depths that require deco or mixed gas would be considered advanced. Cave diving or wreck penetrations I would consider advanced. Basically anything that isn't "recreational-- free to surface without obstacle" diving that can be done easily and safely on compressed air (without mixes) I would generally consider advanced.
If I can do it on regular air and I'm not in an overhead environment, it might take more experience to be comfortable but that's not really "advanced", it's just more experienced.
