Why Advanced Open Water Diver? After your five dives, you`ll be more experienced, comfortable and confident in the water; you`ll enjoy diving more because you better understand the underwater environment. We guarantee there`s no better way to spend a weekend than scuba diving on Oahu. How long will it take? Five dives in two days and your course is complete. A three-tank dive on Saturday (late afternoon deep, twilight shallow, night shallow) and a two tank dive on Sunday. All boat dives… All the time. You will also need 2 personal dive lights (primary and secondary), a dive knife/tool and a slate. Pre-registration and some independent preparation are required. Special Offer: Save up to $150.00. Combine your AOW training with the PADI Enriched Air (NITROX) Diver Course and save. Combine two great courses in one short, action packed, fun filled weekend and save hard earned time and dollars too. Email or call me now to get started.
