How to become a certified scuba diver on Gili Trawangan
This world’s most popular dive course, often referred to as ‘PADI’, allows you to dive to 18 meters deep with a certified dive buddy. Our 2,5 day course is designed for complete beginners and taught by our experienced multilingual instructors. Our groups are kept small, with a maximum of 4, allowing our instructors to focus on your individual needs and ensure a safe and enjoyable learning environment.
The Open Water Diver course consists of three main parts:
Theory
This is where we explain to you the important aspects of diving; in person and through theory lessons on the SSI app. We will make every effort to break it up to keep things interesting.
Confined water training
We start out in our swimming pool at standing depth to get used to breathing underwater. Through the gradual introduction of basic skills, your confidence will increase surprisingly quickly. By the end of the confined water session you will find you can control your position and depth with confidence and have mastered the basic equipment skills.
Open Water dives
To complete the course we take you on 4 reef dives to the top dive sites on Gili Trawangan, Gili Meno and Gili Air. Your first two open water dives will be to a maximum of 12 meters.
