Freediving Constant Weight

In this discipline, the diver descends and ascends using only their own muscle power while holding a fixed weight. They are not allowed to release or change their ballast during the dive. They must bring the exact same weight back to the surface.

Yes, divers use either bi-fins or a monofin to propel themselves down and up the dive line. The use of fins is what separates Constant Weight from Free Immersion, where divers must pull themselves up and down a rope using only their arms. Monofins are especially popular for achieving record-breaking depths.

Constant Weight is among the most prestigious freediving disciplines, and world record depths are immense. Elite athletes can dive beyond 130 meters (over 400 feet) on a single breath. The combination of extreme depth and physical exertion makes it a premier test of human capability.

No, dropping the weight is strictly prohibited in Constant Weight to prevent cheating and ensure safety. If a diver drops their heavy ballast, the dive is immediately disqualified. They must rely entirely on their physical strength and technique to return to the surface.
