Scuba (short for scuba diving) is an underwater activity that requires proper training, certification and adherence to strict safety protocols. While it is a demanding sport that can be dangerous without proper instruction, the rewards of scuba diving are great. Divers see fascinating animals in their natural habitat, are exposed to a variety of physical challenges and achieve a calm meditative state that can help them reduce stress and anxiety.

The most urgent underwater emergencies typically involve a compromised breathing gas supply, and divers are trained in procedures to donate or receive oxygen from their buddy in an emergency. Additionally, divers often carry an independent alternative air source in case of a failure of their buddy’s tank or their own buoyancy control systems.

During dives, scuba divers typically keep an eye on their air gauge or SPG (Submersible Pressure Gauge) and regularly communicate with their buddy(s) about their remaining air supply. During a dive, a diver may also use a dive computer to track their depth and time underwater and a wetsuit or drysuit to stay warm in colder water conditions.

Many scuba divers own their own equipment, but some rent from local dive shops or purchase it through PADI (Professional Association of Diving Instructors). Once you have your gear, the most important thing to remember is to respect the water and dive within your comfort zone. For example, a strong current can pull you away from where you want to go or make it difficult to get back to the surface. Likewise, diving in large waves can be intimidating, especially for beginners.
