Who can join a specialty diving course?
Most advanced scuba specialties here start from Open Water Diver (WRSTC-recognized). A few ask for extra dives or depth — each course page spells out prerequisites. Most specialties finish in 1–2 days with less classroom time than full programs like Open Water. For step-by-step flow, read our specialty course guide.
Best specialty courses for Koh Chang divers
Our scuba specialties on Koh Chang match the terrain: the HTMS Chang wreck and other wrecks for Wreck Diver, deep profiles for Deep Diver, long reef runs for Nitrox and Navigation practice, and calm night dives for Night Diver. The Deep, Wreck & Nitrox package stacks three certs in one trip — a strong base for specialty diver training before technical or Master Scuba Diver routes.
Wreck, Nitrox, Deep and Navigation specialties explained
Nitrox (enriched air) helps you stay within no-decompression limits with less nitrogen loading. Deep prepares you to plan and execute dives to 40 m. Wreck covers hazards, reels and limited penetration within recreational rules. Navigation builds compass and natural navigation on our local sites. Each is a stand-alone scuba specialty course; combine them as you like.
Which specialty course should you choose first?
Many divers start with Nitrox or Deep; wreck-focused divers add Wreck; Navigation and Night fit almost any path. Not sure? Message us or use the guide above — then scroll to the cards for pricing and booking.
