Get certified in 1.5 days with the SDI Solo Diver specialty.
Imagine: Just you. The reef. The silence. No buddy to coordinate with, no group schedule to follow—only the rhythm of your breathing and the endless blue. That's how solo diving feels when you're ready for it. Not loneliness, but freedom. A deep, quiet connection with the underwater world that rewards those who've earned it.
If you've logged 100+ dives, you know your limits. You know your gas consumption, your buoyancy, how you react under pressure. You've felt the tug of wanting to go at your own pace—to linger at that critter, to follow that ray, to simply be there without compromise. The SDI Solo Diver Course at Chang Diving Koh Chang gives you the certification and skills to do exactly that.
At Koh Chang, we dive reefs and wrecks teeming with life. Picture yourself exploring the HTMS Chang wreck or drifting along vibrant coral walls—completely on your own terms. Before you get there, our course teaches you the essentials: redundant gear setup, self-rescue protocols, and gas planning for solo dives. Safety isn't boring; it's what makes the freedom possible.
This course is for experienced divers, underwater photographers, and content creators who value control, self-reliance, and that unmistakable joy of diving exactly how you want to dive. Two dives over one day. Professional instruction. Koh Chang's waters. Your next step.
