1. What does Fun Dive mean?
It refers to diving by certified divers, led by an instructor or dive guide, that is non-instructional and purely recreational. It is not a course, there is no exam, and the purpose is simply to see fish, see coral, and enjoy the underwater world.
2. How do you pronounce Fun Dive?
Pronunciation: /fʌn daɪv/
Close to the Chinese approximation "翻 呆五" (say "呆五" a little faster, as one sound).
3. Does Fun Dive require certification or not?
Certification is required.
This is strictly different from "Discover Scuba Diving (DSD)". To join a Fun Dive, you must already hold an OW (Open Water Diver) certification or a higher-level diving certification before the dive shop will take you out on the boat.
4. Is Fun Dive freediving or scuba?
It is scuba diving.
Fun Dive specifically means recreational scuba diving with a cylinder on your back, wearing a BCD (buoyancy control device) and breathing air underwater. Freediving is a sport in which you do not carry a cylinder and dive on a breath-hold. The two are completely different.
