PADI Theory: Studying for Open Water Certification
We dedicated the day to reading PADI's home-study materials for our Open Water Diver Certificate. While studying wasn't exactly thrilling, doing it on the beautiful island of Gili Air made it much more enjoyable.

Completing Our Diving Education
Five months earlier, we had started our PADI Open Water Diver course but hadn't finished it. Now in Gili Air, we were determined to complete our certification. We spent the day working through PADI's theory materials, covering everything from dive physics and equipment to safety procedures and underwater communication.
Study Session in Paradise
The theory component of the PADI Open Water course covers five modules:
- Module 1: Introduction to scuba diving
- Module 2: Dive equipment and how it works
- Module 3: The underwater environment
- Module 4: Diving skills and techniques
- Module 5: Dive planning and emergency procedures
Studying this material on Gili Air - with its white sand beaches, swaying palm trees, and crystal-clear waters visible in the distance - certainly beat studying in a classroom back home!
Passing the Exam
After reviewing all the materials, we took and passed the PADI Open Water Diver course exam. The written test confirmed we understood the essential concepts of recreational scuba diving. We were officially ready for our two certification dives scheduled for the next day!
Beach Celebration
To celebrate completing the theory component, we indulged ourselves with a good dinner and a few drinks along the beach. The anticipation of exploring the underwater world was building - tomorrow we would put all this theory into practice beneath the waves.
