I did a 2 day OW class back in November. We were mailed the manual, DVD, tables and eRDP before the course and had to do knowledge reviews before we attended. Saturday morning, we did a quiz for each chapter. After the review, we were given the written test, we scored it together and discussed the missed questions.
We then did pool work (which was actually in a shallow spring). There was also one open water dive in the pm
On Sunday, we went out on the boat and finished our OW dives.
Did I feel confident after the class? Not sure about that. I knew I wanted to learn more, and I have. I have been diving at least one day of every weekend since. Most weekends, I dive both Sat and Sun. I try to dive a variety of conditions, reef, wreck, cavern, springs, fresh, salt. I have also done my Nitrox, AOW, Wreck and Cavern certs. I completed the classroom work for Rescue Diver this evening, and will be doing the practial work this weekend. I'm scheduled to begin Intro to Cave in April. I've got 50 dives under my belt since November, absolutely nothing compared to many many divers. Am I an expert? no way! Did the OW class get me hooked on diving and get me to pursue other training? ABSOLUTELY!! Would I have liked it if I had a longer OW class? Sure, but I didn't.
Quick story. A few weeks ago, I was diving off a boat and was hooked up with an insta-buddy. We talked about the dive plan, and our experience. I had been diving for 3 months, he had been diving for 3 years. We talked about my OW class, and he said, "Oh, you did one of those quickie classes, I don't think those are any good" Then he says "don't worry, I'll take it easy on you". We jump off the boat and drop....well actually, I drop and he starts, then begins floating to the surface fairly fast, then he starts sinking again. So I wait for him to get control and come down and join me. We swim along the reef, and for the entire dive, he is squeezing his nose and blowing. I mean the ENTIRE dive. I keep asking if he is OK, and if he is having ear problems, he keeps signalling OK. 5 or 6 times in 45 minutes, he starts to float up and seems to lose control. Just as I'm getting ready to grab his fin to slow him down, he starts coming back down again. While we're on the reef, I'm doing a nice easy frog kick, with the surge. Surge moves forward, I kick, surge moves back, I hover. He is kicking fast and furious the whole time, but not making lots of headway. Then about halfway through the dive, I look over and he is literally sitting on the reef!!!!!! So I suggest we rise up a bit....poor reef can't defend itself.
We finally get back on the boat and he can barely talk, he is so winded. Then he says "not bad, you'll get better with practice". We go to sign eachother's log books. Him = 27 dives in 3 years. Me = 43 dives in 12 weeks.
Just because someone does a 'quicke' OW class, doesn't mean they are not diving regularly after that, possibly with experienced divers (I have been). It also doesn't mean that they are not seeking further training and experience to improve. I relish the opportunity to learn from experienced instructors. I've been lucky and all my instructors have been amazing. I'll likely be taking regular training in all aspects of diving for as long as I dive.
Are the 2 day classes for everyone? Probably not, but if not for that class, I would not have had some of the most amazing experiences of my life in the past 3 1/2 months.
