Submersibles work on undersea oilwells, recover practice torpedoes, search for sunken ships or things that have fallen off ships and sunk.
They come in different shapes and sizes
Submersibles are commonly used by researchers and security forces such as the navy and the coast guard. The coast guard can use them to inspect the underside of ships for any smuggled items.
One of the major advantage of personal submersibles over scuba gear is you can't feel the changing pressure while ascending and descending.
