And how will you determine if the advice you are getting is good advice? Some of the things I read here on ScubaBoard make me cringe ... because I KNOW it's bad, even dangerous, advice. But I know that from experience. The inexperienced diver has no way to know whether or not what someone is saying is valid information.
This is one of the things that scares me so much about what's going on in dive training. People assign a level of credibility or validity to "the agency" that I don't believe the agencies have earned. In any case, most folks don't research anything but rather just assume that these are the experts.
At least with a formal class, the information you are getting has been "vetted" by people who know what they're talking about. The issue isn't that you're getting bad information ... it's that you're generally not getting enough information.
I disagree. The information is incomplete but there is plenty of bad information in dive training. In the best case, it only makes learning the finer points more difficult. Some examples...The way many individual skills are often taught is all hosed up including but not limited to mask clearing, reg recovery ascents, descents and propulsion.
In the worst case it actually becomes dangerous. For this I would refer to the fairly numerous accidents that have occurred on AOW deep dives. Diving deep before you are good at diving shallow can get you hurt. Demonstrably, standards do NOT require a diver to be good at diving shallow before diving deep. What gets them to participate in that deep dive? The agency and the instructor said it's ok. The most glaring example of a trust-me dive that I know of.
Well, first off ... dive instruction isn't mandatory. Anyone can dive. What that OW card really gets you is the ability to rent gear and get tanks filled at commercial shops. Anyone can purchase dive gear and a compressor and dive to their heart's content without ever having taken a class.

Well, access is the main issue and it's what most students are paying for. I've said this before, the quickest way to improve dive training would be to get rid of certifications all together. Then people would only purchase training that they saw real value in. The training would have to stand on it's own merit.
People take an OW class because they need the card to get air and a spot on the boat. Just stand behind the counter in a dive shop for a few hours if you don't believe that. People take AOW so they can get more spots on boats or into a rescue class. Very FEW people give much thought to whether or not the training is any good. For the most part, nobody cares.
