FREEDIVING

Constant Weight

These are the six competitive disciplines:

Constant weight without fins (CNF)

The freediver descends and ascends under water without the use of propulsion equipment or pulling on the rope. Constant weight without fins is the most difficult and natural depth discipline, because of absolutely no propulsion material to go down in the water. This discipline needs a perfect technique and coordination between propulsion movements and equalization.


Constant Weight (CWT)

The freediver descends and ascends using his fins or monofin without pulling on the rope, only a single hold of the rope to stop the descent and start the ascent is allowed. The freediver has to come back to the surface with the same amount of weight he started. Constant weight is the most common depth discipline of freediving.


Dynamic Without Fins (DNF)

The freediver swims in a horizontal position under water to cover the greatest possible distance. Without any propulsion aids. This discipline needs a perfect technique and coordination between propulsion movements and streamlining.

Dynamic With Fins (DYN)

The freediver swims in a horizontal position under water to cover the greatest possible distance. The freediver is allowed to use only fins or monofin.

Static Apnea (STA)

The freediver holds his breath for as long as possible with his airways submerged, his body either in the water or at the surface. Static apnea is the only discipline measuring the duration. Performances could be done and recognized in both pool and open water.

Free Immersion (FIM)

The freediver dives under water only by pulling on the rope during descent and ascent. Free immersion is the depth discipline with the purest sensations, because of the speed of the water on the body. Performances could be done head first during the descent, or feet first, depending on equalization.

No Limit

These are two disciplines only for record:

Variable Weight (VWT)

The freediver descends with the help of a weighted sled and ascending without the weight and coming back to the surface using fin swimming technique or pulling the rope with the arms.

No Limit (NLT)

The freediver descends with the help of a weighted sled and ascends via balloon filled with air or other buoyancy device. No limit is the absolute depth discipline.
