If you’ve ever dreamed of swapping your office chair for a dive tank and your morning commute for a stroll along a palm-fringed beach, then the Zero to Hero Divemaster Course on Koh Tao might be the life-changing adventure you’ve been waiting for. This is where complete beginners become confident dive professionals—step by step—while training in one of the world’s most popular scuba diving destinations. From your very first breath underwater to mastering every skill needed to work in the dive industry, this structured pathway guides you through each stage with clear goals, expert instruction, and a vibrant community of divers who all started exactly where you are now.
Before you sprint into the sea like an overly enthusiastic dolphin, let’s take this sensibly—one bubble at a time. Scuba diving is extraordinary, but it’s worth easing into. Think of it as a slow-burn romance with the ocean rather than something you fling yourself at without at least learning how to breathe without squeaking into your regulator.
That’s why our Zero to Hero Open Water to Divemaster Program is designed progressively. Each course builds your confidence, skills, and safety, reducing the odds of accidentally swimming upside-down or mistaking your fins for your neighbour’s.
Start at the Beginning: The Open Water Course
Your underwater journey begins with the SSI Open Water Course—a 3-day introduction to scuba diving and the surprising fact that fish have absolutely no concept of personal space.
Duration: 3 Days
Price: 11,000 THB (10,000 THB in the Zero to Hero package)
You’ll move through morning theory, afternoon pool sessions, and your first ocean dives. You’ll learn buoyancy, equipment setup, and the all-important skill of not kicking coral. And yes, you must swim 200 metres and float for 10 minutes—but it’s more “holiday paddle” than “Olympic qualifier.”
Level Up: The Advanced Adventurer Course
Once your fins are pointing in the right direction, it’s time to discover how exciting diving can truly get.
Duration: 2 Days
Price: 11,000 THB (10,000 THB for Big Blue students)
You’ll complete five specialty dives. Popular choices include Perfect Buoyancy, Deep, Navigation, Night, and Wreck Diving. Imagine floating through the ocean after dark with a torch, surrounded by bioluminescence—it’s like drifting through a watery galaxy, but with fewer satellites and more fish.
Fun Dives: The Part Where You Fall in Love with Diving
To start your Divemaster training, you’ll need at least 40 logged dives. This sounds like a lot until you realise Koh Tao is essentially a coral playground filled with swim-throughs, pinnacles, and curious turtles that glide past like elderly neighbours judging your recycling habits.
Fun dives strengthen your skills, confidence, and the kind of buoyancy control that makes other divers think, “Alright, show-off.”
Rescue & First Aid: Become the Diver Everyone Wants Nearby
The SSI Stress & Rescue Course is a 3-day confidence booster that turns you from “good diver” to “reliable human in a crisis.” You’ll learn first aid, CPR, oxygen use, and how to manage emergencies above and below the surface. It’s serious, practical, and somehow still fun—often in a “my buddy is pretending to drown again” kind of way.
The Big One: Divemaster Training on Koh Tao
This is the moment the Zero to Hero Divemaster Course Koh Tao shifts from adventure to profession.
Duration: 4–6 Weeks
Price: 40,000 THB
Our program blends SSI e-learning, leadership workshops, dive guiding practice, buoyancy mastery, deep and night diving, marine life ID, physics, physiology, and a visit to the SSS Recompression Chamber. You’ll assist instructors with real students, guide certified divers, and develop the confidence to brief dive sites without sweating through your rashguard.
Even better—you’ll join a close-knit community known for beach cleanups by day and sunset beers by evening.
Two-Week Divemaster Internship
If you’re serious about working in the dive industry, this internship is essential. You’ll shadow our professional Divemasters, learning guiding, navigation, group control, and the art of climbing a boat ladder gracefully while wearing half your body weight in equipment.
Go Further: The SSI Instructor Training Course (ITC)
Within six months, you could go from beginner to Scuba Diving Instructor, teaching new divers on tropical reefs and only wearing shoes when absolutely required.
Duration: 16 Days
Price: 75,000 THB
Includes: All materials, assessments, prep days, professional kit, and in-depth teaching techniques.
Accommodation for Every Budget
We offer options from budget dorms to private villas, all within walking distance of Big Blue Diving on Sairee Beach. Whether you’re backpacking or embracing your “Eat, Pray, Dive” era, there’s something for you.
Koh Tao Weather: Diving All Year
Koh Tao enjoys warm, tropical weather year-round. Expect 25–30°C water, abundant marine life, and peak visibility between January–May and October–November.
How to Get to Koh Tao
All journeys end with a ferry, whether you fly into Samui, Surat Thani, Chumphon, or Bangkok. Lomprayah runs the fastest connections, with options for every budget.
Booking, Payments & Avoiding That 5% Card Fee
You can book online, pay via Wise, or secure your start date with a deposit. Most long-stay divers use Wise to avoid local card fees and conveniently convert those savings into mango smoothies.
