Deep-sea diving gear typically includes SCUBA, which stands for Self-Contained Underwater Breathing Apparatus. This type of equipment is used by divers to explore the depths of the ocean, allowing them to stay underwater for extended periods of time. SCUBA gear typically consists of a tank of compressed air, a regulator, and a mask. It also often includes fins, a buoyancy compensator, and a wet suit. All of these items are necessary for safe and successful deep-sea diving.
