What do I need to start?

An Open Water certification (PADI or equivalent). That's it - Advanced is the natural next step.

Is there an exam or theory?

No exams and no classroom theory. There's short knowledge reading per adventure dive, but the course is 100% in-water.

What's the maximum depth?

30 meters - that's the deep adventure dive. It's one of the highlights of the course.

Do I have to pay a deposit to book?

Yes - a 3,000 THB deposit secures your spot, and the balance is paid here on the island. Message us on WhatsApp and we'll arrange it in a minute.

Can I do it straight after my Open Water?

Yes, and that's the most popular way to do it. Book both together and we discount the combo - ask us on WhatsApp.

How long does it take?

1.5 days, five dives. You're certified by late morning on day two.
