Course overview

The PADI Enriched Air Diver Specialty certifies you to dive with nitrox, giving you longer no-decompression times, ideal for Koh Lanta's repetitive dives on big sites. With more bottom time you can linger on the deep walls of Hin Daeng and Hin Muang or make back-to-back dives at Koh Haa with a wider safety margin. It is the most popular specialty for a reason: more time underwater and a more conservative profile.
