HTMS CHANG
The approximately 100-metre-long HTMS Chang was sunk off Koh Chang in 2012. Today, its hull and superstructure are home to many fish and make it a special wreck-diving destination.
The upper superstructure reaches to around 7 metres below the surface. We plan which areas to explore based on your certification, experience and the conditions on the day.
YOUR CONTACT & OUR TEAM
I’m Sheila, and I’ve been a dive instructor since 2025. Diving has been part of my life since I was little. My dad is a dive instructor too, and he encouraged me to dive from an early age.
Together with our team of experienced instructors and guides, I’ll help you make the most of your first or next diving experience.
Depending on the activity, language and availability, you’ll be with me or another member of our team.
I look forward to having you on board :)

No. Discover Scuba Diving is designed for your first experience, without a certification. If you want to get certified straight away, PADI Open Water Diver is the beginner course for you. Both are available from age 10; special training limits apply to children.
With Discover Scuba Diving you try diving under direct supervision. You receive an introduction, practise the basics and make two guided sea dives. This experience does not lead to a diving certification.
The Open Water Diver is a full beginner course with eLearning, one pool day and two days at sea, with four training dives on each sea day. Learn about equipment, safety and diving with a buddy. Once you successfully complete all requirements, you receive your internationally recognised PADI certification.
You do not have to try Discover Scuba Diving before taking the Open Water course. Both options are suitable for people with no diving experience.
You do not need to be a competitive swimmer. For the Open Water Diver you do need basic swimming skills: swim 200 metres without aids or 300 metres with a mask, snorkel and fins, without stopping. There is no time limit and you can use any stroke. You must also tread water or float for 10 minutes without swimming aids.
With Discover Scuba Diving there is no such swimming test. However, you should feel comfortable in the water and be able to stay afloat. If you cannot swim or feel unsure, please tell me before booking so we can discuss which option suits you.
Based on the PADI Open Water Diver requirements and the Discover Scuba Diving guidance.
Before a dive course or Discover Scuba Diving, you complete a medical questionnaire. Depending on your answers, a medical examination and written clearance may be required before diving.
You should seek medical advice particularly for asthma or other lung conditions, cardiovascular disease, diabetes, epilepsy or seizures, fainting, ear conditions or balance problems. Recurring sinus problems, mental health conditions requiring treatment or panic attacks may also require assessment. The questionnaire also asks about surgery in the last 12 months and prescription medication. These examples are not an exhaustive list.
A pre-existing condition does not automatically mean you cannot dive. A doctor, preferably with diving-medicine experience, must assess your fitness to dive. Ask for the questionnaire well before your trip and bring any required medical clearance to the course. If you are unsure, seek medical advice in advance. Do not dive when acutely unwell; diving during pregnancy is not recommended.

Maybe, but no one can promise it. Whale sharks live in the wild; we do not feed or attract them. They are occasionally seen around Koh Chang, including at the HTMS Chang wreck and Hin Luk Bat. There is plenty to explore even without a whale shark.
