Absolutely agree, teaching people the right way, even by minimum agency standards, makes them better divers but you can't honestly say that it takes the same time or effort from the staff working in card printing factories.Seaweed Doc did a pretty good job of describing all the standards violations in this incident in post #88, so I won't repeat them.
The difference between OW instruction with students who are on their knees (the traditional way) and students taught while neutrally buoyant/horizontal trim is night and day. At the end of the pool sessions, students taught while neutrally buoyant already look like experienced divers. This takes no more time than traditional instruction. The students are constantly practicing buoyancy, even while waiting for their turn to do a skill.
The first article PADI published on this appeared 14 years ago. It should be standard practice by now, but I am sure most classes are still taught on the knees.
I was offered to be a part owner/manager of a dive centre in the Philippines last year, they average 40 OWD cards a week with 2 instructors employed part time and a boat that would make a pasta strainer look sea worthy in comparison. It's a well respected 5* idc facility.
Have you ever seen a neutrally buoyant class with 6-8 or up to 12 students, one underpaid instructor and at best a skip year zero to hero 1 month old DM (with a hangover)?
I politely declined, not just because of the soul sucking nature of dive centres like those, but I believe that their business model is more likely to sink than said boat.
My point is that those 40 OWD a week hold the big agencies profitable, which in turn makes it possible for the rest of us to enjoy the sport that we love and teach other people that will continue to improve the current methods. Hopefully one day the bubble will pop and stories like the OPs will become less frequent.
