Frequently asked questions about diving on Koh Tao.
Short answers to the practical questions that usually come up before you choose a course or send your dates.
Which course should I choose?
Complete beginners usually start with Open Water. Certified divers can compare Advanced, Rescue, Nitrox, Divemaster and the Complete Diver Package on the Courses page. Send your current certification, recent experience and available full days when you want Lex to suggest one practical route.
Will Lex teach my course?
Sometimes I’ll teach the course myself; sometimes another qualified PADI professional may teach part or all of it, depending on the course and dates. I’m your main contact either way, and the instructor setup is confirmed before you book.
Can I do the course in Dutch or English?
Yes. The form lets you choose Doesn't matter, Nederlands or English. The instructor and language depend on availability and are confirmed before booking.
How do I check dates and availability?
Send your preferred dates, how many people are coming, your current certification or experience and your preferred language through Contact or WhatsApp. Availability and planning are checked before anything is confirmed. Last-minute requests may be possible, but availability is never guaranteed.
How do booking and payment work?
Availability and the final amount are checked first. You then receive the payment details. Your booking is confirmed separately.
Where can I compare current prices?
Use the Prices page for current course prices, combination totals, returning-student rules and private-course upgrades. The exact amount and availability are confirmed after your dates and course fit have been checked.
Can I book accommodation without a course?
No. Accommodation through Duik met Lex is available only together with a diving course. Lex can help arrange the reservation, while Ban’s Diving Resort and reception handle room availability, rates, payments, changes and refunds.
Do I need a medical certificate?
Every student completes the standard diving medical questionnaire. Many students need no further step. When the form requires doctor clearance, the doctor makes the final decision. Divemaster candidates always need doctor-signed clearance dated within the previous 12 months and valid through completion. Read Medical and Fitness to Dive for the full process.
What happens if my plans change?
Contact Lex as early as possible. Any date change or replacement depends on timing, availability and written confirmation. Weather, safety and operational changes follow a separate process. Read Cancellation and Rescheduling for the exact rules.
What should I send in my first message?
Send your preferred dates, how many people are coming, your current certification or diving experience, your preferred language and the course you are considering. Add accommodation needs when relevant. Do not send detailed medical information through the general form.
Send the details you already know.
Lex can help you narrow the options without committing to a booking.
