Book your Sidemount Diver Course in Koh Chang from 9,990 THB. Improve trim, comfort, and redundancy with professional instructor-led training.
The Sidemount Diver Course Koh Chang teaches you to dive with tanks mounted at your sides instead of your back – for better trim, comfort, and redundancy. Whether you're exploring the HTMS Chang wreck or the reefs of the Mu Koh Chang National Marine Park, or preparing for technical diving, this specialty builds the streamlined setup and gas management skills you need for wreck diving and beyond in Thailand's Gulf waters.
Sidemount diving originated in cave and technical diving but is now popular with recreational divers – especially those with back issues or technical aspirations. Our sidemount certification includes 3–4 open water dives from our dive boat, with small groups, boat-supported dives, and professional instructor-led coaching. Book your sidemount specialty on Koh Chang today.
On many days the Gulf side of Koh Chang offers calm, workable conditions—ideal for nailing trim, balance, and gear handling. You get both reef and wreck environments, including the HTMS Chang area, for wreck-oriented sidemount training and line-of-sight skills in real bottom profiles.
If you are comparing a sidemount course Thailand or sidemount certification Thailand and want focused sidemount training on Koh Chang, you get boat-supported dives, quick coaching loops, and a setup that is a natural bridge from recreational comfort toward a technical diving configuration when you are ready to progress.
