Watch as Alexey Molchanov of Russia performs an unbelievable dive to 131 meters (430 ft) under constant weight in a dive time of four minutes and 33 seconds at the VB 2021 freediving competition in Deans Blue Hole on Long Island in the Bahamas.

Constant weight (CWT) is a freediving discipline recognized by AIDA, in which the freediver descends and ascends using their monofin and/or with the use of their arms without pulling on the rope or changing their ballast. Only a single hold of the rope to stop the descent and start the ascent is allowed. Constant weight is one of the eight disciplines considered for international competition. [source]
