The PADI Scuba Diver course is a sub-course of the PADI Open Water Diver course. If you are short on time but really want to become a diver, the PADI Scuba Diver level may be great for you, especially if you expect to dive primarily with a dive guide. This course is an intermediate step towards an Open Water Diver certification.
PADI Scuba Divers are qualified to:

Dive under the direct supervision of a PADI Professional to a maximum depth of 12 meters / 40 feet.
Obtain air charges, rent or purchase scuba equipment, and participate in scuba activities as long as they are properly supervised.
Continue diving training by completing the PADI Open Water Diver certification and taking certain specialty diving courses.

To enroll in a PADI Scuba Diver course (or Junior Scuba Diver course), you must be 10 years of age or older. No previous diving experience is required.

What will you learn?

The PADI Scuba Diver course consists of three main phases:

Knowledge Development to understand the basic principles of scuba diving – only the first three sections of the five of the Open Water Diver course.
Confined Water Dive to learn basic scuba skills – just the first three sections of the five of the Open Water Diver course.
Open Water Dives to use your skills and explore – just two of four on the Open Water Diver course.
