Deepest dive under ice - breath held (no fins, no diving suit, male)

The deepest dive under ice - breath held (no fins, no diving suit, male) is 56 metres (183 feet 8.72 inches) and was achieved by Waldemar Bruderer (Switzerland) in Plaun da Lej, Graubünden, Switzerland, on 27 February 2025.

As an experienced diver, Waldemar's progression to diving beneath ice was a natural one, he says. 'The allure of the crystal-clear waters, the serenity of the underwater world, and the challenge of such an extreme environment captivated me. I thrive on the idea of immersing myself in nature, experiencing it in its purest form. By minimizing equipment, I feel more connected to the elements and can truly appreciate the majestic underwater landscapes.'

Waldemar hopes to raise awareness about climate change and the need to protect our glaciers. He said, 'Living in Switzerland, I witness first hand the impact of climate change and the melting glaciers that define our landscape... This dive is not just a personal challenge; it's a message that we must cherish and protect the natural world we inhabit.'
