The Breakdown of the 3-Day Course

Theoretical Learning with E-Learning
One of the biggest advantages of this course is the e-Learning component. Instead of spending hours in a classroom, you complete the knowledge development online at your own pace before arriving in Koh Samui. This gives you a head start on understanding essential safety procedures, terminology, and techniques. When you arrive, your instructor can focus on practical skills rather than classroom lecturing.
This approach appeals to tech-savvy travelers or those with tight schedules. Plus, it means you’re not rushed during the practical parts, and you can ask questions based on your pre-learning.
Confined Water Training
Once in Koh Samui, the next step involves practicing in a pool-like environment—the confined water dives. Here, you get familiar with your gear, learn how to breathe underwater comfortably, and practice basic skills like regulator recovery, mask clearing, and buoyancy control. According to reviews, the instructors are highly professional and attentive, making first-time divers feel confident and safe.
This phase is crucial because it helps you build confidence before heading into open water. The small group size (max four participants) ensures personalized feedback and plenty of one-on-one time, which many reviewers found valuable.

The highlight of the course is the four open water dives, where you put your skills to the test in the real ocean. You’ll explore vibrant coral reefs, encounter tropical fish, and maybe even spot some curious sea turtles or rays. The sites visited—Koh Tao and Sail Rock—are well known for their marine biodiversity and relatively calm conditions, making them perfect for beginners.
During these dives, you perform various skills under supervision, like ascending and descending safely, and navigating underwater. Once your instructor approves your performance, you’ll earn your PADI Open Water Certification, valid worldwide and allowing you to dive to 18 meters independently.
