Exploring the Course and Its Setting in Koh Samui

The Member Diving school operates out of Koh Samui, one of Thailand’s most popular island destinations, known for its lush landscapes and vibrant coral reefs. The two-day advanced course is designed to build on your existing open water skills, introducing more challenging concepts and helping you gain confidence in the water.
The program is delivered via the biggest boat on the island, a spacious speedboat catamaran that comfortably accommodates up to 40 divers. This boat features a sun deck for relaxing between dives, ample space to walk around, and a friendly, attentive crew serving fruits, soft drinks, and water throughout the day. The catering to comfort and convenience is clear, making each trip feel like a true island adventure rather than just a dive outing.
The pickup service is a nice touch, especially if you’re staying centrally on Koh Samui. Starting at 9:00am, the day usually begins with a smooth transfer to the boat, providing plenty of time for briefing and gear setup before heading out to dive sites.
Itinerary Breakdown: What You Actually Do

On Day 1, you’ll meet your instructor and get a quick briefing about the day’s plan. You’ll then set off on your boat trip, heading to some of Koh Samui’s best diving spots. The first dive often introduces you to the local marine life—expect to see clownfish, corals, and maybe a few small reef sharks depending on the site.
The second dive focuses on applying the skills learned, with your instructor providing personalized feedback. During the trip, the crew keeps you fueled with healthy snacks and plenty of hydration, which is especially appreciated under the Thai sun.
Day 2 continues with dives that introduce you to new specialties, such as underwater navigation or peak performance buoyancy—these are great skills that make your diving safer and more enjoyable. One of the benefits here is the performance-based nature: you get to choose which specialties you want to focus on, making your experience tailored rather than a one-size-fits-all program.
