A PADI ‘Bubble Maker’ course can be completed from the age of 8 but to become a certified Junior Open Water Scuba Diver, you need to be at least 10 years old.
10 and 11-year-olds must dive with a certified parent, guardian or professional to a maximum depth of 12 meters.
12 to 14-year-olds must dive with a certified adult.
At age 15, the junior certification upgrades to a regular Open Water Diver certification.
