Scuba divers typically wear a wetsuit or drysuit to insulate and protect them from cold water, along with a buoyancy control device (BCD) that helps regulate their buoyancy. They also use a scuba tank for breathing compressed air, a regulator to control air flow, and a mask to improve visibility underwater. Additional gear may include fins for propulsion, a weight system for stability, and safety accessories like a dive computer or dive knife.
