Free Immersion
From Wikipedia, the free encyclopedia
Free Immersion (FIM) is a AIDA International freediving discipline in which the freediver dives under water without the use of propulsion equipment, but only by pulling on the rope during descent and ascent.
Performances may be done head first or feet first during the descent, or a combination of the two.
The current record holder is Martin Štěpánek with -106m (in 3min 52s) set on April 3, 2006 at Cayman.
