The world record for the deepest freedive, also known as a no-limits freedive, was set by Austrian freediver Herbert Nitsch. On June 14, 2012, Nitsch reached a depth of 253.2 meters (831 feet) in the waters of the Greek island of Santorini. This incredible achievement was accomplished using a weighted sled to descend and an inflatable lift bag to ascend rapidly. Nitsch’s record-breaking dive demonstrated extraordinary skill, training, and physiological adaptation to extreme underwater conditions. However, it’s important to note that freediving records may change over time as athletes continue to push the limits of human capability in this challenging sport.
