PADI® Advanced Open Water: Your pass to enjoy diving anywhere in the world with a buddy (max. depth of 30 m)! 

2 days | 5 Adventures Dives

Level up your diving skills! 

As an already qualified Open Water Diver, the next step is the PADI® Advanced Open Water course, which, when completed, will give you a license to dive to a maximum depth of 30m.

The PADI® Advanced Open Water course is about improving your underwater skills and learning new techniques, as it is about having more fun!


Who should attend the Advanced Open Water course?


To apply for the Advanced Open Water course, you don't need to be an  "experienced" diver. The course is built to leverage and complete the skills you learned during the Open Water courses.

So this course will be a perfect fit if you have just finished your Open Water license or registered a few dozen dives.

Our highly-trained PADI Instructor from Coral Grand Divers will teach you specific skills and knowledge, supporting you every step of the way. 

Prerequisites Be a PADI Open Water Diver or equivalent, medically fit for diving (Read the PADI Medical Form to check that there are no issues. If you answer 'NO' to all the questions then you are OK to start your diving course and there is no need for you to have a medical check.
If you answer 'YES' to any questions, please let me know. In that case, there are some additional questions on page 2 and a medical check-up may be required before starting your course)
Total time commitment 6 to 8 hours to the eLearning program; 2 days for 5 training dives

Let's go for Five exciting Adventure Dives!

Navigation (Mandatory)


✔️Maintain neutral buoyancy. 

✔️Evaluate the number of kick cycles and the time required to swim underwater at a normal, relaxed pace of approximately 30 meters.

✔️Navigate to a predetermined location and return within 15 meters of the starting point, guiding using natural references and estimated distance measurement (kick cycles or time). Surface only if necessary to verify direction or location.

✔️Position and handle a compass underwater to maintain an accurate heading while swimming.

✔️Navigate without surfacing to a predetermined location, return within 6 meters of the starting point using a compass, and evaluate distance measurement (kick cycles or time).

✔️Swim a square or rectangular pattern underwater, beginning from a fixed location and returning within 8 meters of the starting point using a compass.

Deep (Mandatory)

✔️With a buddy, plan and manage gas usage, including turn, ascent, and reserve pressure. 

✔️Establish no stop-and-dive time limits.

✔️Descend using a line, wall, or sloping bottom.

✔️Compare changes in color at the surface and depth.

✔️Compare a dive computer reading to another diver's depth reading.

✔️Ascend at a rate not to exceed 18 meters/60 feet per minute using a dive computer.

✔️Make a safety stop at 5 meters for at least three minutes.

There are three elective dives that you get to choose from:

Peak Performance Buoyancy Adventure Dive (Recommended)

The essential skill for any confident scuba diver is buoyancy. Improving your buoyancy will give you more control and improve your air consumption. 

Learn how to streamline yourself and your equipment, use your lungs more to control descents, adjust your trim, and focus on swimming, body position, and hovering.

Night Adventure Dive

Learn how to communicate at night and handle a dive torch, as well as entry and exit techniques. You will also learn to navigate a reciprocal heading, a skill you have mastered during the Underwater Navigation dive, but this time you will do it in the dark! Explore the Ocean at night with lots of new cool stuff to spot, including the extraordinary natural phenomenon, Bioluminescence. 

Wreck Diver Adventure Dive

Experience the excitement of diving into a shipwreck. Learn how to safety plan and execute a wreck dive deeper than 18 meters on the HTMS Sattakut.

Underwater Naturalist Adventure Dive

Learn more about underwater life, symbioses between species, underwater ecology, aquatic plants, and animal habitats. 

Fish Identification Adventure Dive

Learn how to identify fish, their family groups, and specific species.

We will also spend time discussing and practicing responsible dive practices to avoid adverse effects on the underwater environment.

Boat Diver Adventure Dive

This dive teaches you specific knowledge about diving off boats, including terminology, typical exit and entry points, and techniques for correctly deploying a surface marker buoy.

Digital Underwater Photography Adventure Dive

Your Instructor will teach you how to shoot stills and understand the basics of exposure, focus, and composition.

Search and Recovery

Learn how to use a lift bag, bring an item to the surface, tie various knots, and perform an underwater search.

Emergency Oxygen Provider

Knowing when and how to administer Oxygen is a valuable skill in a diving emergency. During this course, you will learn to recognize different injuries and illnesses necessitating Oxygen administration.

IMPORTANT! -Flying after Diving

When planning your diving trip and your journey toward your destinations, always remember that you must not fly directly after scuba diving. It accentuates the risk of having decompression sickness.


The PADI guidelines are to NOT FLY during a 12 hours interval after a single dive and 18 hours after multiple dives. As often when it comes to scuba diving, take a conservative approach to safety, and whenever possible, avoid flying the next 24 hours after a dive.

If you intend to do multiple dives on different days during your trip, consider buying your own dive computer, as it will calculate the optimal time to fly based on your diving history.

Even more than other outdoor sports, diving is weather- and sea-dependent. Be aware that some sites might be inaccessible on certain days and that diving trips might be canceled due to dangerous conditions.

Luckily, Thailand has a fantastic climate almost all year round and this happens very rarely.
