The official name is "C card". C is an abbreviation for certification, and if you obtain it, it will prove that you have acquired the knowledge and skills necessary for Diving.

In order to obtain a C-card, it is necessary to take a "C-card course" by the leadership group.

In the beginner's class C card course, you will learn basic Diving knowledge such as how to handle and manage equipment, Diving rules, how to contact sea creatures in the department (classroom), and underwater in the pool (limited water area) course After learning how to set up equipment and how to dive, you will practice what you have learned so far in the ocean training that actually goes out to the sea.
