The explorer made the bold claims in relation to the stolen gold the Nazis hoarded during World War Two.
Some believe it was stored in a secret bunker before the fascist dictator’s suicide
But diver Phil Sayers has now claimed the stash is 450m deep on the bottom of the Baltic sea.
The former professional said that he met a survivor of the tragic Wilhelm Gustloff ship, which was sunk by Soviets in January 1945 killing 9,500 on board.
Mr Sayers, 61, claims that survivor Rudi Lange – who was a radio operator on the ship – saw crates of what he said is Nazi gold being boarded onto the boat.
He did not know what was being taken on at first, but it was not until 1972 when he met up with another survivor – who was one of the guards who had been tasked with looking after the gold and he revealed what was in those huge cases.
Mr Sayers explored the ship in 1988, when he dived into the Baltic to see the ruins.
He said the structure was completely broken up and left in a pile on the seabed – which would have left the crates buried below.
Mr Sayers also took some portholes to the surface, to be placed in a survivors’ museum in memory.
But he realised there were bars across the windows – suggesting they were from a “strong room” that would have been used to store valuables.
The diver, from Essex, believes that these clues point to the existence of the gold.
Nazis were known for taking valuables including art works, gold and other objects during the Third Reich.
Treasure hunters began digging for hidden Nazi gold in rural Poland this summer.
Excavators started their attempt at uncovering the alleged gold in a Nazi train, believed to be hidden between Wroclaw and Walbrzych in western Poland.
The excavations in Walbrzych are intended to uncover hidden treasure from the Third Reich, including priceless gold, jewellery and artworks looted by Nazis and buried in the dying days of World War 2 .
Using heavy equipment, the team started to dig for a hidden railway tunnel as the treasure hunting duo claimed last year to have uncovered the incredible find in an underground chamber.
Workers were pictured last week setting a fence around the area which lines the 65km of the railway track, going from Wroclaw to Walbrzych, near to the Czech border.
Rumours had swirled in the region since the end of WW2 that a train was packed with Nazi loot being moved back to Berlin before the advancing Red Army.
But Polish troops with explosive-detecting devices scoured the ground which the train is said to be buried some 200 feet beneath in the autumn of 2015. They found nothing.
