Divers hovering in open blue water under the dive boat

Advanced Open Water course on Koh Tao

Five adventure dives in two days turn a new diver into a confident one: deep diving to 30 m, underwater navigation, perfect buoyancy, a night dive and the HTMS Sattakut wreck.

Duration
2 days
Dives
5 adventure dives
Max depth
30 m
Requirement
Open Water (any agency)

Your five adventure dives

Deep: descend to 30 metres and learn how depth changes colour, air consumption and dive planning.

Navigation: use a compass and natural landmarks to find your way back to the boat.

Perfect buoyancy: fine-tune weights, breathing and body position so you glide without touching anything.

Night: the reef changes completely after dark, with hunting fish and sleeping parrotfish in your torch beam.

Wreck: explore the HTMS Sattakut, a former Royal Thai Navy ship, safely and responsibly.

Mostly in the water

Each dive starts with a short theory session, but there is no final exam. The course is practical, and you finish as a much more comfortable, versatile diver.

Questions

Do I need to be SSI certified?

No. Any recognised Open Water certification is fine.

I learned to dive years ago. Is that OK?

Yes, but if it's been a while we recommend a refresher dive first (from ฿1,500). Ask us in chat.

Is there an exam?

No. The Advanced course is practical, with short theory before the dives.

Can I do it straight after Open Water?

Yes, it's our most popular combo. The 5-day Open Water + Advanced package is ฿18,000.
