..the total curriculum for wrecks is 2 courses...
I think most agencies have 2 wreck courses - recreational (light zone) and technical (beyond light zone) courses.
RAID have three... which is a curriculum I particularly like. There's a 'basic wreck' (no penetration, 2 dives), then there is 'advanced wreck' (cavern equivalent/light zone penetration, followed by 'technical wreck' (beyond light zone, full cave equivalent).
Most advanced/technical wreck classes require a plethora of technical qualifications as prerequisites (normally around AN/DP or ER level). This differs from cave, whereby the deco aspect is taught in conjunction with the overhead aspect.... and that means more steps needed to be added specifically to the cave curriculum.
In contrast, technical wreck is a separate entity to the decompression. Basic tech prerequisites ensure the student has adequate equipment and protocol knowledge in preparation for the training. Once training is completed... the depth of the wreck environment dived is dictated by the technical qualification held (ER, Trimix etc....)
There are also courses beyond Technical Wreck... dealing with issues like how to pass restrictions properly, stage tank use... and the logistical operations and planning necessary for expeditionary grade technical wreck exploration.
