...Nowadays, it's a recreational sport. Open Water certs have to accomodate people who have not had much experience in the water. In a couple of the modules I did, there were a couple people who literally couldn't swim. In one of the modules they test your swimming proficiency by making you swim 200 meters (or something), gear free. One guy sank like a rock. The other doggie paddled 50 meters and then clung to the edge in exhaustion.
Obviously, the instructors had no choice but to not continue these people forward in the course, but it's an example of just how casual this sport is viewed now.
Thanks for your perspective on this. Although there are some old grizzled divers here that learned under a far different system than people do today, many of us dive with "today's students" and some of us still teach them what's required to dive in our local environments.
Today, the students you've described, may not necessarily be turned away, but provided with fins, mask and a snorkel and asked to reattempt the watermanship requirement. I've seen people with little or no swimming ability certified as OW divers with the blessing of some training agencies that hold a pittiful standard.
The level to which a diver is required to be trained is dependent upon the area in-which s/he wishes to dive. This has been discussed in the previous conversation.
So with this in mind, and the Open Water cert structured to give people who have never even swam in the ocean or snorkled a chance to try Scuba diving, that means they have to focus on the basics. What good is boyancy skills, or knowing how to change the second stages on your reg, or going deep, if it takes somebody two modules to be comfortable clearing their mask?
It's not PADI's fault, it's how the general public views Scuba diving now. Is PADI (and the other agencies), supposed to turn them away?
OR,
Do they make the Open Water cert accessible to all (most) people, not just the naturally athletic and dedicated people? Sure you can keep Scuba difficult to enter by keeping the skills requirements high, but then Scuba suffers globally.
I would suggest that the most important thing is not "in what age" a diver learns to dive, but when he does learn, that he learns an ample amount to dive safely in the conditions present. Just because someone wants to learn isn't reason to certify him. The standard to which he is certified must be a reasonable one under the circumstances.
Courses like Peak Performance Boyancy, Dry-Suit, whatever else... aren't necessary for anything. It isn't a pre-requisite to go diving...
Some skills are required in some locations and not in others (I'm not sure if you would like to go diving in Atlantic Canada without a dry suit). As to Peak Performance Buoyancy, I guess this is a matter of what you consider peak? If the divers are rocketing to the surface and obviously have buoyancy difficulties, why certify them? It's a matter of degrees. What is reasonable in one instructor's mind, is extra training and another course for another. Not all instructors train their OW classes off the students knees.
