Very good thread. Lots of good insight from several vantage points. This thread should be required reading for OW cert. training.
I agree with the concept that some divers need more time in the water with their gear to become competent.
I also agree that competence is relative. It implies a level of ability and skill commiserate with a defined level of training. Not necessarily perfection but competence in the skills required for the activity and within the limitations set by their highest level of training. OW certification has some basic skills that have to be mastered to attain the OW cert. It also has some "limits" associated with that certification. Granted they are recommended limits with no real enforcement (no dive police around to give out tickets) so the limits are only as good as the integrity of the diver.
Beyond the basic skill set is experience. Experience is only gained through doing and learning while doing. That is why different environments are good for a broader experience level. Shore vs boat entry, cold vs warm water, clear vs turbid, choppy vs calm conditions, cloudy skies vs bright sunny ones, different tank sizes, different second air setups, different buddies, different dive times and depths, etc. All these add to the experience base of a diver.
The question becomes when does a diver seek new training? When is he now fully competent to progress to the next level? Who makes this decision?
I don't believe in a certain number of dives to meet any minimum qualification. That is too simplistic and not detailed enough a description to provide the necessary guidance to a diver or an instructor on when is enough; enough? Different conditions and gear need to be part of that equation. If I do 100 20 minute dives in a local lake that is never below 75 degrees and is only 30 feet deep does that demonstrate I am a competent diver? I think not. Competence to me implies varied experiences. I don't think there is any magic number of dives that determines a person competent. One would like to think that a 100+ record of dives would incorporate a variety of conditions and perhaps challenging experiences.
I have an OW cert. I received it 30 years ago. I did a variety of dives during the first few years of my cert. including zero visibility, rescue training dives, cold and warm water dives, shore and boat entry, a variety of surf and swell conditions, deep dives and in different environments--lake, quarry, ocean, farm ponds, etc. Now that I am getting back into the sport do I feel competent to take on more advanced certifications? Yes, and No.
My path back to diving has included several pool sessions with OW classes as well as several dives with OW classes and other dives with more experienced divers under different conditions and with all new gear. After several dives I now feel comfortable enough to take on AOW certification. In fact, I have already done most of the required stuff as part of normal dives while getting my diving skills back and building new ones. Am I a competent diver? For OW skills and beyond, yes. Am I a competent diver for AOW skills, No, that is the reason for the training. But I am an experienced diver so adding the AOW skill set to my current skill set should enhance rather than confound my progress to greater competence in the sport.
Training vs experience can sometimes seem like the "chicken or the egg" discussion. Which comes first, the training or the experience? In practical terms they are really tied to one another. Experience is the practice of training. Training, whether self taught or instructor taught, is education and the application of education becomes experience. We learn by doing. The more we know the "why's and how's" of what we do the faster most of us learn. Education is the why and how, experience is the practice of the various skill sets we learn from the education side of things. Once we become competent in the required skill sets through practice we become experienced. Being experienced is really what we need to have to move on to further complex tasks.
Competence is great but does not show we have the capability of handling new challenges. Experience is based on learning through doing in different conditions and to me, is the true indicator of when it is time to add more complex tasks.
