Sidemount Diver Course Koh Chang – Tank-at-Sides Diving

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 and professional SDI or PADI instruction. Book your sidemount specialty on Koh Chang today.
