Located in South China’s Guangxi autonomous region, which borders Vietnam, Jiudun Cave has two main entrances – North and South. The previous record, also set by Han, was to 767.7 ft (234m) in Jiudun, with entry and descent through the southern entrance and his ascent via the northern arm.
For his latest record, the entry and exit both took place via the cave’s northern arm.
“The north part of Jiudun Cave is quite complex, which makes the descent and ascent more complicated and challenges the support team. At depth, some areas are easy to silt out, which lowers the safety margin and increases problem solving time stress,” Han tells DIVER.
Preparations for the record-breaking dive included the instillation of an underwater decompression habitat from Michael Lombardi in the cave ceiling at 33ft (10m).
