Scuba gear is essential equipment used for underwater diving. The main components include a scuba tank, which holds compressed air, and a regulator that controls the flow of air to the diver. Other important items are a buoyancy control device (BCD) that helps divers manage their buoyancy, and a wetsuit or dry suit for thermal protection. Additionally, divers use fins to swim efficiently and masks to see clearly underwater. A dive computer or depth gauge helps monitor depth and time spent underwater, ensuring safety during dives. Together, these items allow divers to explore underwater environments safely and comfortably.
