Why not? They issue an access credential, thus they function as a filter. Shouldn't it be a meaningful filter?
Not really - you can go diving without the card - there's no law that says you can't. You can also open a shop and sell air to anyone you like - no card required.
dweeb:
One of the leading causes of dive fatalities is heart attacks. We can't say for sure, but everything we know about it says that couch potatoes usually have heart attacks when they get up off the couch and do something active without adequate conditioning.
You're point being? This is probably the leading cause in bowling alley's too, but no one is calling for a fitness test there (or on softball fields, etc).
dweeb:
The more valid question is, how many fatalities result from panic? You ask what in diving induces panic - to you or me, almost nothing. But to a panicky person, lots. Is diving more panic inducing than, say, golf? Maybe not, but panic in diving is far more likely to kill you than panic on the green.
How about behind the wheel of a car? Or climbing up the side of a mountain? Panic is a funny thing - what may panic you today may be small potatoes tomorrow. You can't submit a person to 3 or 4 instances and deduce if they are prone to panic, or if they would panic in that same situation the next time.

I said here that I prefer the European model - Americans taking the German driving test have a 75% failure rate.
Do you know why? It isn't that the test is particularly difficult in the driving portion - sure, there is a required night & autobahn portion (big deal - don't pass on the right). However, you do have to know some mechanical aspects about the car and the test is only in German (at least it was 7 years ago). Of course, they allow *anyone* who has a drivers license in another country to drive for 1 year without such testing, so I don't know what good you feel it does. Also, a license there is valid forever - even if you go blind. Lastly, about 1/2 the states in the US have reciprocity - you can apply for a license and never take the test.
dweeb:
Not when that training confers a credential, like a medical or law degree, a driver's or pilot's license, or a diving certification. Dive training is not a class in flower arrangement.
As I said, " if you already have the knowledge and the skills, training is just an affirment of that." That's exactly what a driver's or pilot's license affirms - there is no presumed training. Same with passing the bar.
dweeb:
Not necessarily. There has been a concurrent increase in supervision, which is annoying to the competent.
Exactly where is this true? In my travels, I find that there is no problem finding a shop/boat that will simply transport me to and from a site (no in-water supervision). Of course, for those that want a DM/tour guide, businesses have been quick to fill that need.
dweeb:
There have also been numerous posts about accidents and near misses here that never seemed to show up in "official" listings.
As far as "near miss" - nobody that I know attempts to list them. Please name a specific dive related death (even an MI) you are aware of that was not in the DAN statistics. I am willing to believe there are a few out there, but not a significant %.
dweeb:
This was a student with a 3.8 GPA -they would have put forth the effort if they had the expectation it would be necessary.
So the supposedly bright student underestimated the course requirements - the system still worked correctly - it was the student's fault for not applying themselves, or simply not being able to do the work. GPAs don't really impress me, nor do degrees - at least not as a measure of anything having to do with diving.
