Ninja freediving duckdives - updated

Hey all,

Here is a little video of Sarah Whitcher demonstrating some of the smoothest duckdives in history.

We've been using this short clip very successfully in our courses, can only recommend.

This is also good to refute any arguments of "I need weights to get down." - Note how buoyant Sarah is.

Is this a salt water pool? If not, I'd like to see this done in the ocean. Also with a wetsuit and without weights. ;-)
But seriously: great skill, technique, posture, etc.

Concenring buoyancy, I don't know if "not having to use weights" can be generalized though. Some people even sink with full lungs (without a wetsuit and without weights) whereas I have to empty my lungs far beyond FRC to be able to sink (in the same conditions). I'm not all that sure if buoyancy exclusively depends on technique.

This being said: it remains a fact that learning to duck dive properly is a must for freediving (unless you only do static and DYN/DNF, of course)! This is a great video, and who am I yo argue with the woman who designed a one breath CO2 table where you have to endure 60 seconds of contractions on each breathhold when I can only do 20 seconds.

Buoyancy is a physical property and does not depend on technique, but is defined by the average density of the freediver, as defined by has contained in the body, body mass and volume and equipment mass and volume.

What Sarah shows here (and equally well in salt water) is that a freediver can descend into the water efficiently and gently even with very high positive buoyancy that is beyond reasonable for freediving.

She shows that any safely weighted freediver can learn to start their dive efficiently without adding weights.

Any information that discourages dangerous habits such as over weighting to descend easier is welcomed in my book and by the vast majority of us one breath folk I would imagine Carry on the good work!
