Open WATER AND ADVANCED COURSE on Koh Tao
Start your journey into the underwater world and build your skills with our Open Water and Advanced Course combo package. This beginner to advanced diving option lets you start from scratch and get SCUBA certified as an advanced-level diver, quickly and easily.
The Open Water and Advanced Course package allows you to learn the basics of diving and then immediately build on those skills to reach new depths—literally! With just two extra days of diving beyond the Open Water Course, you’ll earn your Advanced Adventurer certification, extending your dive limit to a maximum of 30 meters.
Why Should I DO BOTH COURSES TOGETHER?
In just five days total, you’ll transform from a complete beginner to an Advanced Adventurer, gaining confidence and control underwater.
Our experienced multilingual instructors are with you every step of the way, teaching at your own pace so you can fully enjoy this unforgettable dive training experience.
Combining both courses is the perfect choice, as you can expand on the freshly learned basics directly with the comfort of a known environment & Instructor who can advise you to get the most out of it.

At Ease in the Water
It’s helpful if you feel generally comfortable in the water and have basic swimming abilities.

If you’re unsure about this, feel free to ask us about other course options!

To start this course package, you need to be at least 10 years old. If you’re between 10 and 15 years old, you’ll be certified as a Junior Open Water Diver and must dive with an adult until you’re 15 years old. Please note that 10 and 11-year-olds are limited to a depth of 12 meters, while 12- to 15-year-olds are limited to a depth of 21 meters.
