William Trubridge Sets Freediving World Record (VIDEO)

William Trubridge has set the world record for the longest dive without using fins in the Bahamas.

The 29-year-old New Zealander was able to free dive to a level of 380ft in the Atlantic Ocean, during the Vertical Blue free immersion competition at Dean's Blue Hole.

"It was hard to get the tag from the bottom as I struggled with some narcosis," Trubridge said afterwards said. "But it's great to have the free immersion record again."

Nitrogen narcosis, which effects divers reach depths of more than 100 feet, produces a physical state similar to drunkenness.

The record is Trubridge's 10th, making him likely to be the best free diver in the world.
