scuba gear commonly includes: one or multiple air cylinders (or with different mixtures, like nytrox), a regulator with 2 mouthpieces and a pressure gauge, a weight belt to help with buoyancy control, fins, diving goggles, a snorkel, a BCD that can inflate or deflate to help achieve neutral buoyancy and a dive computer to monitor depth and dive time. divers may also wear a wetsuit to help reduce heat loss while underwater
