Blue water is best for underwater photography of people. Two of Taiwan’s islands, with consistent blue water are both off the south east coast, Green Island and Orchid Is.
The above picture was taken in Australia.
Taiwan has untapped potentials for underwater exploration by amateurs.
A good move would be to adopt the European scuba certification system offered by CMAS (of France). It should have English text books by now.
Another alternative to the controversial PADI franchise certification system is NAUI.
The world federation CMAS is the better alternative. It is not affiliated with any major equipment manufacturer.
An even better idea would be to promote breath hold free diving. Good for the lungs both now in the present and decades later as the diver ages. I can vouch for this.
The benefits of free diving are getting greater confidence with the sea, the health aspects, the much lighter and easier to handle equipment.
Scuba has become a tourist thing that people try for a short while and then do something different.
Spear fishing might be added to the skill of deep free diving. Acceptable when pelagic fish are sought and reef fish avoided. Spearing big pelagic fish is expensive. Taiwan would be an ideal. Divers drift offshore in the open ocean waters and wait for tuna and marlin to swim close enough for a shot. A boat is necessary.
Personally I do not encourage anyone to attempt free dives beyond 33 meters.
Some girls are doing 66 meter free dives and even deeper. A lot a practice and guidance is involved with these attempts. All take the diver to a brink of suddenly going unconscious and is best avoided.
Deep free diving has been called the most dangerous sport in the world.
