Price range: ฿5,970 through ฿19,900
The PADI Eco Open Water Course is an enhanced beginner certification that pairs the standard PADI Open Water Diver curriculum with two additional PADI specialties, AWARE and Peak Performance Buoyancy, in the same 3-day format. Divers leave Koh Tao with three certifications, refined buoyancy control, and formal marine conservation training, instead of the single certification a standard Open Water course provides.
New divers are focused entirely on survival during their first open water dives: clearing a mask, controlling breathing, managing air. Body position gets little attention as a result, which is why standard beginners commonly contact the reef with fins, gauges, or knees, kicking coral and disturbing the marine life they came to observe.
The PADI Eco Open Water Course addresses this directly. Rather than treating buoyancy as a skill to refine later, it builds Peak Performance Buoyancy training into your first certification, alongside PADI AWARE marine conservation training, standard curriculum plus two specialties, in the same three-day timeline.
The result: divers who leave Koh Tao already diving cleanly, not divers who spend their first dozen dives elsewhere learning what should have been covered from day one.
Most beginner courses in Koh Tao teach the minimum PADI requires to pass, no more. The Eco Open Water course costs more because it delivers more: an extra open water dive, an additional specialty certification, and buoyancy training most divers don’t receive until years into diving.
Buoyancy control, holding a fixed position in the water column without rising or sinking, is typically introduced at a basic level in standard Open Water training, then refined later through the PADI Advanced Open Water course. The Eco Open Water course moves that refinement forward: the full Peak Performance Buoyancy specialty is built into your first certification, covering the breathing control and weight distribution techniques instructors use to stay motionless mid-water.
The PADI AWARE certification included in this course covers marine ecosystem function and threat identification beyond the standard curriculum. It’s built around the PADI AWARE Foundation framework, the conservation program dive operators worldwide use to train divers on reducing physical contact with reef ecosystems, turning what you learn into measurably lower-impact diving, not just awareness.
Constant fin movement to hold position raises heart rate and increases air consumption. Precise buoyancy control removes that correction entirely: divers who master it early consume air more slowly and get measurably longer dive times as a direct result, not as a side effect of experience.
Graduates of the Eco Open Water course earn three distinct, globally recognized PADI credentials:
Every course fee includes the equipment, materials, and logistics needed for the three days, nothing to arrange separately before arrival.
Earning three certifications typically takes longer than three days. This course is structured to fit the same three-day timeline as the standard Open Water course, with no extra days required. Here is the schedule.
*This schedule can be changed due to the weather and other factors
The Eco Open Water course costs more than the standard course because it includes an additional open water dive and two additional certifications. Here is the direct comparison.
| PADI Open Water (the “Standard”) | PADI Eco Open Water (the “Eco Upgrade”) | |
|---|---|---|
| Time | 3 Days | 3 Days |
| Open Water Dives | 4 Dives | 5 Dives |
| Certifications Earned | 1 – Open Water Diver | 3 – Open Water Diver, AWARE, Peak Performance Buoyancy |
| Details | Core buoyancy, safety, and dive-planning skills required for independent diving anywhere in the world. | The same independent-diving standard, plus Peak Performance Buoyancy and PADI AWARE training built into the certification itself. |
| Price | ฿3,600 – ฿12,000 | ฿5,970 – ฿19,900 |
| Verdict | The globally recognized certification at the lower price point. | Three certifications and advanced buoyancy training in the same three days. |
Booking the two specialties as part of Open Water certification, rather than adding them later, costs meaningfully less than purchasing them separately, and avoids returning to a classroom for material you’ve already covered once.
With all three certifications complete, you’re positioned to continue directly into more advanced diving or applied conservation work.
The PADI Advanced Open Water course extends your certified depth to 30 meters, including access to deeper shipwreck sites. Because Peak Performance Buoyancy is already complete, it counts toward your Advanced Open Water course credit.
Your AWARE training applies immediately to local marine protection trips we run around the island, including debris collection dives and reef monitoring surveys. Participation doesn’t require diving, you can support the same conservation work by helping spread AWARE’s guidance on protecting the local marine environment.
The Eco Open Water course is the more thorough starting point: the same lifetime certification as the standard course, plus buoyancy control and conservation training most divers only pick up after years underwater.
Reserve your dates, receive your e-learning access, and begin the course that gets you diving cleanly from your first certified dive.
A few requirements apply before starting the PADI Eco Open Water Course:

Choosing a premium dive package comes with distinct advantages. Here is how the eco-certified course flow works.
Yes. Upon successful graduation from this package, you will hold three independent PADI certifications. Your profile on the PADI app will display your digital licenses for Open Water Diver, PADI AWARE, and Peak Performance Buoyancy Diver. This instantly proves to dive centers worldwide that you are a highly capable, low-impact diver.
New divers often struggle with horizontal alignment, causing their legs to drop and scrape the ocean floor. Mastering your trim early protects the coral reefs from accidental fin strikes. Additionally, excellent body positioning dramatically lowers your physical exertion. When you move efficiently, you consume less air, allowing you to enjoy longer dive times on every single trip.
No, because we use a highly efficient linked-dive strategy. PADI training standards allow us to evaluate your performance for multiple certifications simultaneously during your open water training. You complete the exact same amount of pool work and core ocean dives, but your underwater tours are structurally optimized to test your buoyancy execution, meaning you save massive amounts of time without cutting corners.
5,970-19,900 THB depending on season and booking class (24H Flex, Saver, or Secure). See the comparison table above for how this compares to the standard course
You need to complete a continuous 200-meter swim, or float/tread water for 10 minutes, as part of PADI’s entry requirements. If you can’t yet meet this, Discover Scuba Diving may be a better starting point.
It’s not harder; it’s more comprehensive. You cover the same core Open Water skills plus buoyancy and conservation training, at the same instructor-to-student ratios and safety standards.
