aYou’ve just finished your Open Water Diver course, your logbook still damp, your mask hair freshly earned, and your ego inflated to match your BCD. The reef has welcomed you, the fish have tolerated you, and now you stand at a crossroads: do you grab your fins and head out on a few fun dives around Koh Tao, or do you jump straight into your Advanced Open Water Course on Koh Tao and unlock the mystical powers of deep diving, wreck exploring, and night navigation?
To Dive or To Advance?
It’s a common dilemma for new divers in Thailand’s scuba diving paradise, but fear not—this is where we break it down, bubble by bubble. Whether you’re here to rack up dives or dive deeper into the unknown, we’ll help you decide the best way to get the most out of your time—and your tank—on Koh Tao.
So, dripping with seawater and self-satisfaction, you’ve cleared your mask without drowning, inflated your BCD without rocketing to the surface like a Coke bottle with Mentos in it, and—most importantly—proven to the scuba gods that you can breathe underwater without panicking, screaming, or kicking a passing parrotfish in the face.
Congratulations. You’re officially certified not to die in shallow water. This is no small thing. The SSI Open Water Diver course is the scuba equivalent of being handed a license that says, “Can dive! Must travel!.” It’s your golden ticket to fun diving adventures across the globe, assuming those adventures occur no deeper than 18 meters and in daylight, warm weather, good visibility, and perfectly cooperative marine life.
Which brings us to the Big Question:
Should you get some more experience doing fun dives first, or should you go ahead and do your Advanced Diving Course straight away?
In the spirit of fairness, let’s entertain the idea of “gaining experience” through a handful of fun dives before doing the Advanced Open Water course. It’s a perfectly reasonable notion, kind of like saying, “Maybe I’ll just drive around the parking lot a bit before I take the highway.” And yes, fun diving is, well, fun. You’ll log some dives, meet a few turtles, and develop that mysterious underwater hand signal language that no two divers seem to use the same way.
The Advanced Course
But here’s the thing. Doing the Advanced Open Water course doesn’t mean you’re suddenly Jacques Cousteau with a GoPro. It’s not an exam, or a competition, or even particularly difficult but more of a “greatest hits” album of scuba diving. Night diving! Wreck diving! Deep diving! Peak Performance Buoyancy, aka “How Not to Look Like a Floating Potato”! And most importantly: the deep dive. This gets you legally certified to dive to 30 meters, which—trust me—is where a lot of the really good stuff lives. Giant groupers, dramatic topography, maybe even the odd shipwreck or whaleshark if you’re lucky (and yes, you will be lucky on Koh Tao).
Without the Advanced Diver certification, you’re stuck in the 18-metre kiddie pool. With it, you’ve got access to some of the best dive sites around Koh Tao, including the majestic Chumphon Pinnacle, the thrilling Sail Rock, and the eerie HTMS Sattakut wreck, all just begging for a visit. These aren’t places you want to miss because you’re stuck at the surface blowing bubbles at the braver folk below.
Becoming a Better Diver
The Advanced course might sound intimidating, but it’s actually one of the most enjoyable and relaxed ways to build your diving skills. It’s less about formal testing and more about hands-on experience through five exciting adventure dives. You get to focus on enjoying the dives, building confidence, and fine-tuning your technique. The reward? Access to deeper, more dramatic dive sites and the chance to explore a whole new underwater world.
And where better to do it than right here on Koh Tao, Thailand’s undisputed capital of diving dreams? Warm, vibrant coral reefs, and more dive schools than there are pad Thai stalls, here is the perfect place for your underwater skills. Some schools offer Advanced diving courses that are affordable, fun, and utterly unforgettable.
So don’t dither. Don’t wait. Dive in—literally. Do your Advanced Open Water Diver course on Koh Tao. It will open the door to deeper depths, cooler sites, and brighter bioluminescence. Become the kind of diver who doesn’t just visit the reef, but explores it properly. Night dives, wreck dives, 30 meters of pure oceanic wonder—it’s all yours for the taking.
Besides, let’s be honest—nobody ever brags about staying in the shallow end.
