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 William Trubridge with a depth of 108m in a dive time of 3min 51s, set on April 11, 2008 in Dean's Blue Hole, Bahamas.
