Nitrox Course

Ko Lanta Diving Center offers Nitrox training in two formats: a one-day theory-only course at THB 4,500, and a two-day course with two dives included at THB 8,500. Both options lead to Nitrox certification; the difference is whether you want to log the first dives on enriched air as part of the course or take the theory alone and apply it going forward.

Nitrox extends no-decompression limits at recreational depths, which on a multi-dive day in the southern Andaman — where the boat runs two or three dives back to back — has practical value. Certified Nitrox divers can request fills at centres that supply enriched air, opening up options on liveaboards and at sites where repetitive diving is the format.

The centre has the infrastructure to support Nitrox: two compressors on board ChockSomBoon 1 and the equipment to handle enriched air fills. For divers doing the two-day course with dives, those dives take place on the same southern Andaman sites the centre accesses on its regular daily boat trips.

For divers already certified who want to add Nitrox during a stay on Ko Lanta, both course options can be fitted around regular guided dive days at the centre.
