I'm interested in learning about the different kinds of scuba diving equipment.

There are two main types of scuba diving equipment: surface-supplied and self-contained. With surface-supplied equipment, a diver is tethered to an air tank on the surface via a hose. This type of equipment provides the diver with breathing gas and buoyancy control. Self-contained equipment includes a regulator and compressed air tank that can be worn by the diver, allowing them to breathe underwater without being tethered to a surface supply. Both types of equipment provide the diver with the ability to explore deeper parts of the ocean.
