The SDI Advanced Diver Development Program was created to make truly “Advanced Divers”. During the course your SDI Instructor will take you through four SDI specialties (deep, navigations, photo, video, etc. as examples) covering all the skills and subjects, so that by the end you will feel comfortable conduct dives of a similar nature. Once you have logged your 25th dive (these can included any and all training dives) visit your local SDI facility with your logbook and four SDI Advanced Diver Development specialty cards and you will be awarded the SDI Advanced Scuba Diver certification. By earning the SDI Advanced Scuba Diver certification you will increase abilities and comfort in the water and be ready for the next step, SDI Rescue Diver.
