Advanced Open Water

The PADI Advanced Open Water course at Hammerhead Divers covers five dives across two days, with e-learning handling the theory side. It's a direct continuation from Open Water certification — no additional academic prerequisites beyond completing the theory modules online. The two-day, five-dive structure keeps the course compact without compressing the dives themselves.

The Advanced Open Water qualification extends your certified depth from 18 to 30 meters and requires two mandatory dives — Deep and Underwater Navigation — plus three elective specialty dives chosen from the PADI specialty catalog. At Hammerhead, the specialty options include Nitrox, Photography, and Rescue as stand-alone courses, which gives a sense of what electives are likely available as part of the Advanced program in this location.

In the Sea of Cortez, the Advanced course opens up the more interesting site options that aren't accessible on an Open Water ticket. Gordo Banks — Hammerhead's pelagic dive listed specifically for advanced divers — becomes a realistic target once the Advanced certification is in hand. The deep dive component of the course, completed in Cabo's waters, is where most students get their first experience at depths where nitrogen narcosis can start to become a factor and where managing bottom time and ascent rate requires more attention.

The e-learning component means the academic prep for each specialty is done before the water session, so dive time stays focused on practicing what the theory covers. Instructors hold NOM-09 certification alongside their PADI credentials. The same four-diver-per-guide maximum that applies to all Hammerhead trips applies here — a meaningful difference from larger operations where training groups can run six to eight students per instructor.
