Not dived for a while? We can help you back into the water with a Scuba Skills Refresher. Keeping your knowledge and skills up to date is a very important part of diving safely. Over time however, skills and knowledge are forgotten, resulting in problems remembering how to check equipment properly, taking a long time to descend, equalising ears, properly adjusting buoyancy and so on.

Take your diving skills to the next level with the Advanced Adventurer course. This great course not only certifies divers to depths of up to 30 meters, it’s also a fantastic opportunity to improve buoyancy, air consumption, and confidence in the water, leading to longer and more relaxed dives.

Enriched Air Nitrox on Koh Lanta with Dive & Relax

As you learned in your Open Water Course, too much Nitrogen can be a bad thing. Enriched Air gas mixtures contain more oxygen and less nitrogen which means that during a dive, our tissues are exposed to a lower partial pressure of nitrogen.

Are you tempted to go a little bit deeper on your dives? Do you want to explore shipwrecks, walls and canyons that lie beyond the limits of your current dive certification?

Why Koh Lanta?

Scuba diving around Koh Lanta is relatively easy. Most dive sites are in the 5m - 25m depth range where we have the most sunlight, best colours and widest diversity of marine life on the coral reefs.

The dive sites, marine life and coral reefs are far more extensive, diverse and healthier in the Andaman Sea compared to the Gulf of Thailand. The perfect environment for teaching all SSI courses.

Ringed Chromodoris (Chromodoris annulata)

Visibility at Koh Lanta's dive sites is usually pretty good, often at least 5 - 15m around Koh Bida/Koh Phi Phi and usually more like 15 - 20m around Koh Haa.

Sometimes visibility can be amazing, at certain times of year extending beyond 30 - 40 m around Koh Haa..

The easy dive sites and good underwater conditions around Koh Lanta are fantastic for teaching scuba courses, from the beginner level SSI Open Water Diver, the SSI Advanced Adventurer course, through to the more challenging Diver Stress & Rescue course.
