One of the most enduring mysteries on this planet—alongside why mosquitoes exist and how airline meals can taste both bland and alarming—is the question asked by thousands of aspiring dive professionals every year:
“How much does the Divemaster course cost on Koh Tao… and what exactly am I paying for?”
It’s an excellent question, and a surprisingly sensible one, given that scuba diving is a hobby known for persuading otherwise rational adults to spend large sums of money in order to sink gracefully beneath the waves like enthusiastic, carbon-based pebbles.
But luckily for you, Koh Tao—this small, improbably charming island of dive boats, sunsets, and sunburnt backpackers—is one of the most affordable places on Earth to complete your Divemaster training. And Big Blue Diving, with its seasoned instructors and mildly chaotic boat stories, remains one of the island’s longest-running professional training centres.
Why Koh Tao Is One of the Best (and Most Affordable) Places to Become a Divemaster
Koh Tao has, almost accidentally, become a global powerhouse for professional scuba training. This is due to a peculiar combination of factors:
Experienced instructors who have somehow managed to stay both competent and sun-kissed year after year.
Year-round diving conditions that range from “perfectly pleasant” to “positively postcard-like.”
Lower living and course costs than almost any other major dive destination on the planet.
The result?
You get high-quality Divemaster training without needing to sell a kidney or remortgage your sense of financial dignity.
So, What Is the Divemaster Course Cost on Koh Tao?
At Big Blue Diving, the price for the Divemaster course typically ranges from 30,000 to 40,000 THB.
This varies slightly depending on training agency, materials, and optional extras, but the key point is this:
You’re paying for a full professional-level program taught by highly experienced instructors with access to excellent facilities and a glorious variety of local dive sites.
It is—if I may be bold—extraordinary value.
What’s Included in the Divemaster Course?
When you see a price tag, the natural human reaction is to ask:
“Yes, but what do I actually get for that?”
At Big Blue Diving, the answer is: “Quite a lot more than you’d expect.”
Professional-Level Dive Training
Workshops, theory sessions, safety protocols, rescue skills, dive planning… all the things that make you feel remarkably competent underwater. Aswell as a day with Big Blue Tech & another with our inhouse Marine Biologists at Big Blue Conservation.
Unlimited Diving During Your Course
This is the golden phrase of Koh Tao.
Unlimited diving means you can log dives until you forget what dry hair feels like.
Real-World Experience Assisting Instructors
You won’t just watch videos or practise on mannequins. You’ll assist with real courses, real divers, and occasionally real people who put their fins on the wrong feet.
Access to Big Blue’s Dive Boats
Large, stable, and strangely comforting vessels that reliably transport humans to the best dive sites around Koh Tao.
Equipment Workshops & Tank Handling Training
Learn to handle scuba gear with confidence instead of the usual “why does this buckle exist and what is it doing to me?” confusion.
Site Briefings & Navigation Training
Because guiding divers requires more than pointing vaguely and hoping for the best.
Personal Mentoring
One-to-one coaching from experienced professionals. Think of it as scuba tutoring, but with far nicer scenery.
What’s Not Included?
(Important information for anyone wishing to budget like a responsible adult.)
Most dive centres on Koh Tao—Big Blue included—follow the industry standard where training fees exclude:
Training Materials
SSI or PADI digital manuals (7,000–12,000 THB).
Professional Registration Fees
Annual agency membership once you qualify.
Personal Equipment
Some divers prefer to buy their own masks, fins, or dive computers. Rental options are widely available.
Everything is clearly laid out, so there are no surprise charges—unless you count the inevitable cost of ice cream between dives.
Living Costs on Koh Tao During Your Divemaster Course
A Divemaster program usually lasts 6–8 weeks, and living on Koh Tao is delightfully affordable. A realistic budget might look like this:
Accommodation: 8,000–16,000 THB per month
Food: 10,000–15,000 THB per month
Scooter rental: 3,000–4,000 THB per month
Fun extras: 5,000–10,000 THB
Most people spend 40,000–60,000 THB during a full 2-month stay, depending largely on how often they mistake “hydration” for “ordering another beer.”
Why the Divemaster Qualification Is Worth Every Baht
Completing your Divemaster course on Koh Tao isn’t just about learning to lead dives.
It gives you:
A professional diving certification recognised worldwide
Work opportunities as a dive guide
The option to progress to Instructor
The freedom to work seasonally around the world
A foot in the door for dive-centre management roles
Big Blue Diving also has a habit of hiring from within, which means your Divemaster course can very naturally become your first stepping stone into the dive industry.
