Cave diving depth world record

On the 3rd of November 2023 Frederic set a new world record on a depth of 308 m for the deepest cave dive.

During cave diving in the resurgence of Font Estramar after a series of long dives to test the equipment and protocols, on Friday, November 3 Frederic started his dive in Font Estramar cave in France. After passing the current EOL at 260 meters, he has driven his Seacraft Ghost to explore the cave down to -308 meters.

Faced with the configuration of the cave, Fred chose to separate the dual Seacraft GHOST scooters and use one as the primary scooter, and the other as a backup unit. Fredric and his team are currently using ENC3 navigation console data to understand the topography of the cave as precisely as possible, but also for medical decompression reports.
