Divers qualified to PADI Scuba Diver may upgrade and become Open Water Divers. This usually takes a maximum of 2 days. They will need to do the surface swim, two additional knowledge development modules, the quiz and a multiple choice exam. They will also need to complete two confined water sessions and two open water dives. After completing the upgrade to Open Water they will be able to enjoy dives up to a depth of 18m. The depth limit for Junior Open Water divers (10 – 12 years old) is 12m.
