without aqualung or flippers
A diver has set a new world record after swimming 380ft under water without the aid of oxygen or flippers.
Going barefoot, New Zealander William Trubridge held his breath for four minutes and nine seconds to break the record for the deepest free immersion dive.
He carried out the daring feat - in which in he battled the disabling condition nitrogen narcosis - at Dean's Blue Hole, the world's deepest underwater sinkhole, in the Bahamas.
Depth charge: William Trubridge held his breath for four minutes and nine seconds in order to swim to and from the bottom of Dean's Sink Hole in the Bahamas
Wearing a specially designed silicon-coated wetsuit, Mr Trubridge, 29, used a form of breaststroke to propel himself down to without an aqualung.
‘It was hard to get the tag from the bottom as I struggled with some narcosis,' he said afterwards.
‘But it's great to have the free immersion record again.'
It was Mr Trubridge's 10th world record, Freediving Suit and puts him in first place for the competition to find the world's best all-round freediver.
He performed the dive during the Vertical Blue Suunto Dive-Off competition where last week set another record in a discipline called ‘constant weight, no fins' to 301ft.
Later on his Facebook page Mr Trubridge wrote of his disappointment at not reaching an extra 7ft.
‘So 118m (387ft) CWT was just out of my reach today,' he wrote on the social networking site.
‘I managed to equalise to the plate, wasted some time fumbling for the tag, then set off for the surface.
‘I had to use my arms a little from 20m, but reached the surface and struggled through a samba to do the surface protocol, going overtime by several seconds.
‘That was my best shot, so I will concentrate on the other disciplines for the remaining days.'
During free immersion events, Freediving Suit divers must retrieve a velcro tag from a metal plate set at the specified depth before returning to the surface.
They are not allowed to use any equipment such as fins during their ascent, but are able to use a rope to pull themselves upwards.
The previous free immersion record was set by Martin Štěpánek of the Czech Republic in the waters off Sharm el-Sheikh in Egypt last year.
Freediving Suit has become an increasingly popular extreme sport.
In April last year British freediver Sara Campbell broke a female world record by diving 314ft at Dean's Blue Hole, holding her breath for Freediving Suit three minutes, 36 seconds, before safely returning to the surface.
