freediving
Apnea-based underwater descent
Freediving is underwater diving without breathing apparatus—the diver descends on a single breath and returns before needing air.
Competitive freediving measures depth, distance, or time submerged.
The term distinguishes the practice from scuba diving: She switched from scuba to freediving to experience the ocean more directly.
