So you would say it is all about the possibility of depth? In 'not advanced' areas there is always a hard bottom at 130 feet or so? Aren't you just as screwed at 250 feet as 300 or 500? My point being does 1500 feet matter?
So for you it is the current? I sort of always looked at it like the weather. Everyone talks about it, but no one does anything about it. Seriously, though it goes and you go with it. In faster current, the DM parks the leaders behind a coral head in the lee of the current and shortly the group is tight again. I mean I guess that is more advanced than some dunk down, swim around and come back up in the same spot. My later check out dives were on the east side of Antigua. It was surgey I guess. Getting back on the boat was timing the ladder, it came down, grab it and a second later you were out of the water. Now that was hard.
That kinda says the problem is really training doesn't train you? If you are new you are still expected to do all those things you were told not to do? Most of the problems I have watched seem to be comfort issues, like:
1. Not enough weight;
2. my mask leaks;
3. I cant get down.
4. I can't clear my ears.
Most of these divers seem to relax and then things are fine. Is it just me or is most of the challenge in one's own head?
How much diving do you have to do to go to 60-70 feet? For me, from the begining it was the first 40 feet getting my ears straight and in the 'groove'. 40 to 70 didn't seem that different. Other than getting to surface in a hurry, (which means bad stuff is happening anyway) what is the difference but numbers on a console?
Two things this brings to my mind. In a strong current, the group can get a little strung out, but that train is going in one direction. I could never wonder to far off because of the current. Now that I don't get the 'close' eye of the DM like when I was new, sometimes the missus and I lollygag and the group gets ahead while we are taking pics. If riding the reef "low and slow" put us behind, we just come up a little where the current is faster and catch up.
I don't disagree that everyone should have a SMB. I do disagree that the recent accidents confirms it. I *think* all we know is the diver started for the surface. I don't think we know if she surface or if she did, if she remained there. For all we know this could have been some sort of medical issue that caused it and condition had nothing to do with *causing* the loss.
As for the DM, I would say I think divers should be *prepared* to have a DM who is useless for their safety, but they should EXPECT a DM who puts their safety and care at the top of the list. I don't think a tour guide only DM is acceptable.
Well, the definition of necessary comes into question. I have NEVER shot my bag. (Yes, of course I should practice it. Maybe next time?) That being said I have never seen the need. My DM shoots it and delivers divers to the boat as need. I did see another member of our group shoot hers last trip. She didn't NEED to, but she choose to do it on her own rather than let the DM do it. I take it that is the way her usual op does it since she was a rather experience diver. Through the capitan off a bit as he wasn't aware she was going to break the routine and didn't recognize her SMB.
So anyway, my point is you should have them, but you don't need to USE them.
I get the gear sales. I had a great instructor for the class and confined OW, but they did also talk me into the top of the line, just introduced, fins. Man they were expensive..... And 59 is old? I dove with good divers in their late 70s early 80s. Good diver under water. Does it take something away from the younger, fitter, more gung ho diving crowd's ego when old, fat people dive just fine?
Well someday I will try something else. maybe... You keep scarying me with all this talk of no current? So like how far do I gotta swim? Sounds like work..... I might be not young enough, fit enough or experience enough for that!
Seriously though for you current equals advanced? In the Caymans can you not pay attention and go deep enough to kill yourself? It just seems, with the exception of the rare downwellings, most of all the 'issues' that seem to make some think Cozumel is advanced diving is mostly about divers given the opportunity to do stuff they have been trained not to do and thereby put themselves in danger.
