Why Nitrox?
The Nitrox Diver Course is one of the most valuable certifications in modern diving. Using enriched air (up to 40% O₂), you’ll reduce nitrogen buildup, extend your dive time, and feel less tired after your dives. It’s smart, safe, and perfect for repetitive diving on Koh Chang’s vibrant reefs and wrecks.
