Diving gear refers to the equipment used by divers to explore underwater environments safely. Essential items include a wetsuit or dry suit for thermal protection, a mask for clear vision, and fins to aid swimming. A scuba tank provides breathable air, while a regulator controls the air flow from the tank to the diver. Additional gear may include a buoyancy control device (BCD) to help manage buoyancy, a dive computer for tracking depth and time, and weights to counteract buoyancy. Safety equipment, such as a dive knife and signal devices, is also important for emergencies.
