Scuba diving equipment is essential for underwater exploration and safety. The main components include a scuba tank, which holds compressed air, and a regulator that controls the air flow to the diver. A buoyancy control device (BCD) helps divers manage their buoyancy, allowing them to float or sink as needed. Additional gear includes a wetsuit or dry suit for thermal protection, fins for efficient swimming, and a mask for clear vision underwater. Divers also use a dive computer to monitor depth and time, ensuring a safe diving experience. Proper equipment is crucial for enjoying the underwater world safely.
