rbolander:The quality of the courses depends entirely on the outlook and intent of the instructor(s) teaching to the course, which I'm sure you know - Why the hate for the wreck course?
The quality of the course is first determined by the standards as written by the agency.
Wreck Diving is a course that definitely holds value - Anyone interested in pursuing wreck diving should take it as an intro course - I have no doubt in warm areas that the course is probably lackluster at best, but my observation of the instruction of this course on the Canadian West coast has been that the instructional quality has been top notch (having heard by word of mouth). By and large, doing even non-penetration wreck dives in the environment Canadian waters offer is beyond intimidating - Having supervised instruction, basically a mentor to take you on a tour, is the safest way to decide if you want to continue your wreck diving education.
The wreck course is just flat out scary. The course optionally includes penetration however the instructor can qualify to teach the course without ever having had any training in overhead diving themselves. No line drills are required on land and the line drills required in open water don't even come close to what is required in any cavern course. And then there's the gas management issue. They don't bother teaching you to shoot a bag in this course either. The course certainly doesn't present much information on "wrecks". I don't even see how they could call it a wreck diving course.
