Most leaks happen around the parts that pass through the shell: the skimmer, the return fittings, the light niche and the main drain, as well as the plumbing joints just behind them. The shell itself, whether plaster, gunite, fiberglass or vinyl, leaks less often than people expect. When it does, the leak is usually at a crack, a seam or a penetration rather than in the open floor.
That is why leak detection checks each system one at a time. Each of these areas fails in its own way and sounds different during testing, and ruling them out in order is faster than searching the entire pool.
