Theory
Either in a classroom with us, online or via an app, the theory section is broken down into sections, followed by a review or quiz. It finishes with a 50 question multiple choice exam, sounds scary but you will see how much you have learnt.
Confined water
In the pool, you are shown step by step the skills you need to become a diver. each skill builds to the next one, increasing your ability and comfort slowly but surely.
Open Water
Where we want to be, we will take you to some off Khao lak’s local dive sites, where you repeat some of the skills you learnt in the pool, in a real dive situation. Once all the skills are complete, that’s it, you will be an open water diver.
