Become a PADI PRO diver

Becoming a professional diver is one of the most exciting choices you can make in your personal life. You need the proper training and support to grow as a professional and as a person.

Coral Grand Divers offers the unique opportunity to become a highly qualified professional diver. Our top-level PADI Course Director Alexander Arnold can teach the highest level of PADI ranking. From the Divemaster qualification, the Open Water Scuba Instructor, to the Master Scuba Diver Trainers certification, including numerous PADI specialties.

Our diving school is the ideal place for learning, with a dedicated diving classroom and pool to learn the theory and practice in a safe environment.

The Divemaster (or "DM") qualification is the first step of the Pro ladder. To become a Divemaster, you need to take the PADI Divemaster course and have passed a few other milestones: you need 40 logged dives before you can start the course, and qualify, you need to have at least 60. Once qualified as a Divemaster, you can guide certified divers on "fun dives" and help instructors train new divers.

To become an Open Water Scuba Instructor (or "OWSI"), you must have the Divemaster qualification and have completed at least 100 dives. Instructor qualification involves completing the Instructor Development Course (IDC) and passing the Instructor Examination (IE). Coral Grand Divers is one of the few diving schools offering an IDC preparatory course.

Most instructors become Master Scuba Diver Trainers, or "MSDT." There is no course or exam for this, but you must complete several steps before qualifying. You will need to have certified at least 25 PADI divers and the ability to teach five specialties, so you will need to pass the requirements of five PADI Specialty Instructor courses. An MSDT internship is an ideal way to do this and gain experience while teaching enough students to earn this level of certification.

As divers look to the Divemaster, instructor candidates respect IDC Staff Instructors. As the name suggests, these assist with Instructor training and share their wisdom and experience with new PADI Leaders. The IDC Staff Instructor course gives you in-depth knowledge of the instructor training process and prepares you to shape the new generation of PADI professionals. It's also a great career choice.

Marine life around Koh Tao

Koh Tao, a popular diving destination in Thailand, boasts a vibrant marine ecosystem. When diving or snorkeling around the island, you can expect to see a variety of marine life, including:


  • Butterflyfish: These colourful and graceful swimmers are a common sight.
  • Barracudas: Particularly around Chumphon Pinnacle.
  • Angelfish: With their striking patterns, they are a treat to observe.
  • Groupers: These are larger fish, often found lurking around rock formations.
  • Triggerfish: Though they're fascinating to watch, some, like the Titan Triggerfish, can be territorial.
  • Nudibranchs are tiny, colourful sea slugs beloved by macro photographers.
  • Batfish: These flat silverfish can often be seen in schools.

Corals and Anemones

Soft corals, hard corals, and sea fans can be found in many dive sites around Koh Tao.

Anemones, often home to the clownfish or "Nemo," are also common.

Other Marine Life

  • Sea Turtles: Hawksbill and green turtles are often spotted.
  • Whale Sharks: Although not guaranteed, there are times, especially between March and April, when these gentle giants can be spotted around Koh Tao.
  • Stingrays and Eagle Rays: They can be observed in sandy areas.
  • Moray Eels: These often hide in crevices but can be seen poking their heads out.
  • Sea Snakes: Banded sea kraits are venomous but generally not aggressive.


Crabs, shrimps, sea cucumbers, and urchins are among the many smaller creatures that divers and snorkelers might spot.

Sharks in Koh Tao

Koh Tao, located in the Gulf of Thailand, is a renowned diving destination and offers the opportunity to spot a few species of sharks. While diving around Koh Tao, the following types of sharks might be observed:

  • Whale Sharks (Rhincodon typus): Although not seen daily, these gentle giants are the most celebrated visitors to Koh Tao's waters, especially around popular dive sites such as Chumphon Pinnacle and Southwest Pinnacle. They are typically spotted more frequently between March and April, but sightings can occur throughout the year.
  • Blacktip Reef Sharks (Carcharhinus melanopterus): These are one of the more common sharks spotted around Koh Tao, especially in shallower waters. They are often seen around dive sites like Shark Bay and Aow Leuk.
  • Bull Sharks (Carcharhinus leucas): There was a time when the Bull Sharks gang were a common sight around Koh Tao. We used to guarantee shark sightings at Chumphon Pinnacle during specific seasons, with instances of up to 15 sharks at once. However, they mysteriously vanished in 2010, only to reappear briefly in 2014 at Sail Rock for a few months.

It's worth noting that there's no guarantee to spot sharks on every dive, as with all wildlife. However, Koh Tao's waters offer a diverse range of marine life, and every dive presents the possibility of a memorable encounter. If you're keen on seeing sharks, you can contact us and ask about recent sightings and the best times or dive sites to increase your chances. Always ensure to dive responsibly and observe sharks from a respectful distance without attempting to touch or disturb them.
