Mike Edmonston,
Thanks for the suggestion. Actually, as far as advanced Nitrox, stage and Deco procedures... I thought that's what the DSAT Tec Diver Level 1 was all about? My understanding was it would expose me to the procedures, gear, and dive physics or theory needed and could also contribute to later DSAT courses if interested. If that isn't the case, then what organization/course would you recommend?
To be honest with you, the certifying agency really doesn't matter. Find a good and reputable instructor and ask him some questions / tell him your intentions. You can get really good training from TDI, NAUI, IANTD, ANDI, GUE etc... I did not mention PADI, as I am unfamiliar with their program.
Good luck, and if you need more info PM me.
Cheers
