AIDA Freediving World Championships Video

Take a deep breath, now hold it!

In the Constant Weight (CWT) discipline freedivers descend and ascend using fins or a monofin as well as their hands for propulsion but without puliing on the rope. Whilst divers in the Constant Weight Without Fins (CNF) discipline descend and ascend without the aid of fins.

Wolrd records in the Constant Weight (CWT) category stand at a depth of 124 metres, reached by a German, Herbert Nitsch in 2010, whilst in the female category, Sara Campbell has touched in at 96 metres in 2009.

Using the rope - dynamic apnea in diving parlance - saw a Russian, Alexey Molchanov bottom out at a remarkable 250 metres in 2008.
