OFFICIALLY it's known as a 'forward three-and-a-half somersaults with one twist pike' but unofficially it's the 'firework' and Tom Daley hopes it's the dive that turns London bronze into Rio gold.
The former world champion knows he needs to push the boundaries of his sport and spent most of last year battling to master his 'demon' dive, a dizzying combination of somersaults and twists he had hoped would prove the difference.
However, along with new coach Jane Figueiredo, he spent the winter modifying a new plunge, something that has never been attempted before.
Daley spent long hours on the trampoline, perfecting technique, before building the dive in stages from different heights.
It was painstaking and detailed work, but the dive finally got its premiere at the British Championships and was part of Daley's repertoire when he won silver, with a personal best score, at the recent World Diving Series in Dubai.
"There was a sense of relief when we decided to bin the old dive, but the pressure was on to come up with something," admitted Daley.
"The old dive did terrify me and, while I did conquer my demons with it, it's a weight off my shoulders that I've moved on because it was a bad dive for me.”
It's six years since Daley won his breakthrough world title in Rome, one year after making his Olympic debut as a 14-year old in Beijing.
Last year, there were inaccurate reports that Daley was to call time on his diving career, but he insists he's enjoying the sport more than ever, following a decision to relocate from Plymouth to London.
His home pool is now the Olympic pool, a place with happy memories, and he'll be the star attraction at next month's FINA Diving World Series, May 1-3, in his newly-adopted home town.
