Advanced Adventurer is basically a sample platter and not a level of training from SSI, just a cool card to have
The quote is from SSI's website description of Advanced Adventurer
SSI's progression (That seems to matter beyond cards) is Open Water Diver, Specialty Diver -- 12 dives and two specialty course, Advanced Open Water Diver -- 24 dives and four specialty courses, and then Master Diver 50 dives and the addition of Rescue Diver to previous training.
The quote is from SSI's website description of Advanced Adventurer
This program allows you to experience five different open water dives from five SSI Specialty programs without requiring you to complete the entire Specialty. If you are unsure of your next step, this is the perfect way to advance your dive skills and experience, and to identify which Specialty programs interest you. You will earn the SSI Advanced Adventurer certification after completing this program.
Attention: The Advanced Adventurer certification is not counted towards the AOWD Recognition. To achieve one or more specialty certification(s) for the AOWD, you may decide to complete one or more of these specialties. Your dives from the Advanced Adventurer course will of course be counted.
