free diver
Tankless underwater swimmer
A free diver is someone who dives underwater without breathing apparatus, relying only on held breath.
The practice ranges from recreational snorkeling to competitive depth diving.
Free divers train to extend breath-holding capacity and equalize pressure at extreme depths: Free divers can descend hundreds of feet on a single breath.
