What is scuba diving in Nha Trang?
Scuba diving is an underwater activity where divers use a self-contained apparatus to breathe compressed air while submerged. Equipped with an air tank, mask, regulators, and a Buoyancy Control Device (BCD), divers can precisely manage their depth, buoyancy, and dive time. This allows for safe descents between 10 to 30 meters—and deeper with advanced certifications—to explore the marine ecosystem firsthand.
