Actually, I don't think there will be much of a conflict at all. While reviewing and understanding the dive tables is a very good idea, it shouldn't keep you from going forward with the AOW class.
I'm originally PADI certified, and have my AOW through PADI, but have come to think that SDI has one of the better advanced diver programs. To quote the SDI
Advanced Diver Development Program:
- "The SDI Advnaced Diver Development Program was created to make truly "Advanced Divers". Under the old way of training a student could take and Andvacned Course right after an Open Water course and have a total of nin (9) dive sall under the direct training of an instructor. The SDI Advanced Diver Development program requires a new OW student to take and complete four (4) SDI specialties or equivalent, along with having a total of twenty-five (25) logged dives. SDI feels a diver will truly be "Advanced" after this is accomplished."
Back in early to mid summer 2000, we had a discussion on what is an Advanced diver. At that time, I had just completed my AOW training, but had told the shop to hang onto my card since I didn't agree that I was truly and advanced diver (at the end of the class, I had just 14 dives total). So much improvement in skills and increase in confidence occurs over the first 25 dives that I strongly agree with SDI's standard of that many dives before conveying the "title" of Advanced Diver. Plus when you are finished, you have 4 additional certs that will help you in the long run.
After reading all of this, here is what I would do.....interview the instructor and ask him/her what will be taught and how indepth will it be taught. Make sure it's to your satisfaction. If the PADI class is still your desire, also ask what it would take to be certified in one of the "Adventure" classifications (such as night, navigation, drysuit, etc).
Also, be sure to report back on your progress. Hearing how the other diver's progress is something we all enjoy.
