PSAI Cave Diving Programs



As with all technical diving, our training programs start here in Hong Kong. We can do quite a bit here to prepare you. For any overhead environment, your buoyancy control must be pretty much pitch perfect, we can can do line drills both on land and underwater, and if your goal is to become a full cave diver, you'll also want to be at least Advanced Nitrox or Extended Range diver to be able to conduct decompression dives.


The nearest cave system where we do the actual penetration dives is Sai Siu Saan near Foshan in China. If you are doing overhead programs with us, you are likely to get familiar with the place. It is an ancient flooded quarry with crystal clear fresh water and offers very good diving in both overhead and open water parts of the quarry with depths down to 40m. Another cave dive location we often go to is El Nido in the Philippines, but our divers have trained in other parts of the world, too: Florida, Mexico, etc.


We are constantly looking for new cave systems in China and once you have progressed far enough in your training you'll be very welcome to join our expeditions.

How long does it take?

The duration of the courses vary. Cave diving is a process: you attend training sessions and earn the ratings along the way.

If you have successfully completed the PSAI Advanced Buoyancy Control with a twin-tank or sidemount set-up and other pre-course work , your dive skills are up to it and the logistics work out, you may be able to complete the full PSAI Overhead Program (Cavern, Intro to Cave, Apprentice Cave and Full Cave) in 7-8 days. In most cases, though, divers complete the course requirements in stages spanning over a much longer time.



All overhead programs start with getting your skills - especially buoyancy control - up to the levels required from divers in overhead environments with the PSAI Advanced Buoyancy Control course. The ABC is done in Hong Kong (or sometimes in Guangzhou).

There are no caves suitable for diving in Hong Kong. All cave dives are conducted abroad. Cave dive training you can join is arranged in caves in China, Philippines, Florida and Mexico several times a year.

How much does it all cost?


Cave diving is fairly expensive. There is no way around that. You need full technical gear set-up with other cave diving equipment: dive lights suitable for overhead environment, reels, etc. Cave diving locations are often difficult to reach so there will be travelling costs.


We quote the courses as 'Tuition Only', you will then pay for the dives and travel as you go.

Professional Scuba Association International (PSAI) Complete Overhead Program consists of four stages:



These can be completed one or more courses at the time, or if logistics and your time allow, in one complete program.
