Bob Croft literally rewrote the book on deep breath- hold diving. At the time of his first record attempt, the U.S. Navy diving manual clearly stated that breath-hold diving below 120 feet could prove fatal. Despite this warning,Bob decided to test the limits of human freediving potential. On February 8, 1967, holding a heavy lead weight in his hand, he hurtled beyond a depth of 200 feet, and into history.
