Q: Do I need to be a strong swimmer to start my Open Water course?

You don't need to be an expert, but you must be able to swim 200m unassisted and float for 10 minutes to pass the skills test.

Q: How many days does a standard PADI Open Water course take on Koh Tao?

Typically 3 to 4 days, depending on weather conditions and your personal learning pace during pool and ocean sessions.

Q: Is scuba gear rental included in the course price?

Most reputable schools include full rental gear in the package, but always confirm if fins, masks, or computers are extra.

Q: Can I take the course if I have a medical condition?

You must complete a medical questionnaire. If you have conditions like asthma, you'll need a doctor's clearance to dive.

Q: What happens to my course if the weather is too rough for diving?

Instructors prioritize safety. If weather is bad, sessions are rescheduled or moved to a sheltered pool area.

Q: Should I book my course in advance or walk in?

Booking in advance is better to secure your preferred dates and instructor, especially during the high season (Feb-Aug).
