The record for deepest Freedive with no air or fins is 66m deeper than the max allowed for recreational scuba diving!
Scuba diving is dangerous enough. If you don't get the Bends by ascending too fast, you could just run out of air and never make it to the surface at all. However, free diving may be even more dangerous.
Free diving uses none of scuba's equipment (fins, air, etc.) But instead relies on a single breath of air and the diver's own physical prowess.
The record of deepest free dive without fins is 101 meters set by William Trubridge in 2010. Trubridge successfully completed the dive at Dean's Blue Hole in Long Island, Bahamas. The Blue Hole is one of the largest sinkholes at 202 meters.
A video of Trubridge, who started freediving at the tender age of 8, shows him descending into the black depths of the hole on only one breath of air and then returning back up to the surface. He wears goggles, a swim cap and a wet suit but otherwise uses no equipment.
