I have said this before, and since this thread has been around for awhile, I may have even said it earlier in this thread.There's a bunch of poorly trained, certified divers out there who would be making shops money, if they'd been taught correctly in the first place....If we want to fix the industry, that's where we need to start.
When I was working on my IDC and diving in the shallow waters of Key Largo, I saw a young woman nearly crawling on the sand. She was obviously grossly overweighted. The look on her face was something close to pain. My immediate reactions were 1) she is hating every minute of this dive and 2) no student of mine will ever look like this.
In the dive shop where I used to work, in the midst of an argument about training quality, the Director of Instruction told me "Instructors are a dime a dozen"--about every two weeks some new instructor walks into the shop looking for work. Every one of them has exactly what the shop's owner was looking for in an instructor--the ability to certify divers who would buy gear and go on shop-sponsored trips. The quality of the divers produced did not matter one iota to him. An instructor who did not like the way things were could be replaced in a heartbeat.
The key is indeed right there in the hands of the shop owners. All they have to do is make it clear that they want quality training, and it will happen.
