Looks like you've got the bug and you want to expand your skills. This two-day course will introduce you to deep diving - down to 30m (100ft) and some additional navigation to help find your way around. Then there is a list of optional dives from which you can choose another three fun things to do.

You might want to take photos or videos; learn about finding and recovering objects from the seabed; visit a shipwreck, find out more about marine life...

One of the most important reasons to take the Advance Open Water course is that you will have a much wider range of dive sites open to you by being able to dive to 30m. Most shipwrecks are too deep for Open Water divers. The course is also required as a pre-requisite for other PADI courses.

Cost of course: 14,500 baht. Time required: Two days.
