We recently uploaded a video to our YouTube Channel (
www.youtube.com/user/lakehickoryscuba), pondering the question, "Has Diver Training Really Been Watered Down?" .... snip..... And GO.
I'm going to give you an instructor's opinion about this.
How I learned
computers
I took my initial training in 1984. I have a pretty good memory of the things the instructor talked about. We were well drilled in tables because we didn't have computers back then (there were some but they were mysterious, expensive and not terribly reliable and only technical divers had them as far as I knew). In terms of gas planning we were taught NOTHING beyond the general rule to surface with a 25% buffer.
risks
What I can remember about my OW course is that the instructor went into a lot of detail -- a LOT of detail -- about the potential risks and injuries related to diving. Once certified we were under no illusions about what COULD happen. Anno 2018 and the general tone of the course is to de-emphasize the risks and to emphasize the fun. This could be seen as watering down the course to some degree because I believe it is in the student's best interest to fully understand the risks.
deco theory
Pertaining to decompression theory. We were drilled to be fully capable of planning any dive within the NDL's on the tables and indeed I did my first 600 or so dives using tables. At some point I did what a lot of divers did, which is to use the 120 "rule", which I found "close enough" for the dives I was doing at the time. As for understanding deco theory in general, we got ZERO information in our OW course about how the deco models work. We also got ZERO information about mitigating factors, like safety stops, or risk factors like cold, dehydration, working hard on the bottom, the effect of ascent rates with respect to risk and so forth. We were told to follow the small bubbles but even that was not given a lot of emphasis.
trim and buoyancy control
Aspects of trim and buoyancy control were given ZERO attention in our OW course beyond the ability to hover for 1 min (at that time the standard was to hover for 1 min) and to keep buoyancy control within a couple of meters of the agreed upon depth during the check out dives. Buoyancy control was given slightly more emphasis at the AOW level (which is another post) but the entire concept of trim was never even introduced.
The rest of the standard was very similar to the way it was before the recent improvements.
How I teach
computers
These days, of course, the computer is ubiquitous. I no longer teach the tables except as an historical footnote. I do tell students that if they want to know how the tables work that I am more than happy to show them but I strongly advise them to buy a computer and to dive with it. Simply put, computers are better than tables for measuring nitrogen loading in every measurable way. Moreover, and I'm sure every instructor will tell you this, the ONE THING that people coming in to a "scuba review" have forgotten how to do is to plan a dive.
What I do with all of the time I save not having to drill tables with students is to spend that time on safe diving practices. Best practices. I don't cut back on the amount of time I spend with students but the time spent is MUCH more productive than it was -- in my experience -- in 1984. My students are also coming out of the course able to plan any dive they want using a computer.
With respect to gas planning, EU norms supersede all agency standards so all instructors in Europe are required by EU rules to teach gas planning. This notwithstanding, the quality of information available, and being taught, is generally very good in this part of the world. This is a VAST improvement over what was taught in the past.
risks
As I alluded to above, I think that modern training glosses over the risks too much. Personally I give the risk factors what I believe to be appropriate attention in the OW course but I find that to be a balancing act. I am fully in favour of emphasizing the fun aspects of diving but I think that delaying a detailed awareness of risks to the Rescue course is ... well ... thoroughly idiotic, to be blunt. So I go into a certain amount of detail during the OW course, particularly with respect to causes and dangers of barotraumas and DCS. I don't know why PADI (or is the shops I've been working for) think that if you talk about risks that you will scare students, but I don't believe it. I think someone well armed with knowledge is a better diver. I try not to make it heavy but I don't skirt around the issue either. This is one area where I believe training has been watered down. I believe PADI has a financial motive for this and the shop DEFINITELY has a financial motive to get people diving (and buying gear) asap but that's not my focus. My focus is making sure that my students know bloody well what they are getting themselves into and that includes discussing the jagged edges where things could go wrong. In my opinion the Rescue course should be about handling an emergency, not learning about the risks.
deco theory
without going in to a lot of detail, the way deco theory is taught today (at least by instructors who I know who really understand it) is VASTLY SUPERIOR to how it was in the past. This may not be universal so I should qualify that by saying that almost all of the instructors at the shop where I work have had technical training and several are active technical divers. Dropping tables was the best thing to ever happen to students' understanding of deco theory. We now have to actually teach them what is going on instead of just following a "cook book" to get an NDL. In my OW course I do not go into detail about what to do if they get outside the NDL, but I do explain that it requires procedures that they will not learn at this level and that they should not experiment with it. However, I do not teach them to FEAR the NDL, which is what my instructor did in 1984. Interestingly, my own instructor was a commercial diver who taught PADI courses on the side so he understood this stuff but felt that it was better to instill fear in his students. In addition, the way we teach it, the risk factors are fully laid out and the connection between DCS and these risk factors, in particular, ascent rates, is given sufficient attention. In terms of avoiding a potential DCS, I believe my students have an exceptionally good understanding of the theory that is light years beyond anything that was taught in the 1980's.
trim and buoyancy control
Obviously attention for trim and buoyancy control are an integral part of the modern standard. Some instructors are still struggling to learn how to teach this so we are currently in a transition. However, the fact that there is ANY attention being given to trim and buoyancy control is an improvement over the past. If there is ONE thing I could point to and say that I sincerely believe has improved the quality of diving generally, it's this. I know a lot of people share stories about terrible divers and there are a multitude of videos showing bad trim and buoyancy control. Some of those are obviously snapshots of divers who are not having their best moments and some are genuinely distressing. However, if we had had the same amount of video being made of divers in the 1980's then your toes would curl. I don't know if any of you have the Jacques Cousteau film series on DVD but I do and when you watch it the quality of their diving is utterly abysmal by modern standards! I'm serious. This is another area where we have made great improvements over the last 30-odd years.
As for e-learning
A final word about e-learning. As an instructor I am a HUGE fan of e-learning. Having spent countless unproductive hours basically reading the book to students who couldn't be bothered to do their homework I now have e-learning. In my case, if you don't do your homework, you don't dive. So that's the motivation right there. I haven't changed the amount of time I spend (much) on theory, but I can now spend that time on relevant topics, like deco theory, trim and buoyancy control, dive planning (including gas planning) and bridging the gap between theory and practice, in particular with respect to local diving, which in our area is not trivial because of conditions (mostly visibility and cold temperatures). As a result my OW students are coming out of class a LOT better prepared in terms of theory than they did before we had e-learning.
My Conclusion (tldr
Having learned in 1984 and only having "gone pro" in 2002, I believe I can compare the system that I was taught to the system I teach and on several fronts I have a strong conviction that things have significantly improved over time. With respect to delaying knowledge transfer of the medical risks of diving I believe that the accent should not be put on the Rescue course, which many divers never take, but on the OW course, when that knowledge is perhaps most relevant to their development as divers. In my opinion the Rescue course should be about handling an emergency, not learning about the risks. That last point could be considered "watering down". As for e-learning. E-learning is best thing to happen to diver training since the invention of the dive computer.
