Many people regard cave diving as the most dangerous sporting activity one can choose to pursue. It is an activity which requires the most high-tech equipment in order to explore the increasingly hazardous unknowns. Extensive training, experience and preparation are essential for these divers to survive the depth or distances that are covered. Cocklebiddy Cave in Australia has the longest known underwater series of passages covered by man at 5290m however its depth barely reaches more than 30m. Nacimiento del Rio Mante in Mexico by contrast attains a staggering depth record of 267m.
