Freedive world champion William Trubridge says tomorrow's 102 metre dive is not only a passion but "unfinished business".
At 7.40am, New Zealand time, the former Hawke's Bay man will plunge into a deep, dark hole in the Bahamas, attempting a world record.
It is being touted as the "sequel" to his initial 102 metre attempt back on December 2, 2014 where he diced with death and failed to set a world record.
He had to pull out of the dive just 10 metres from the surface on the return journey, grabbing a guide rope and nodding to his support divers to help him.
The 35-year-old said he knew he was about to black out and did so for several seconds when he broke the surface.
