(USA Freediving) - Shelby “Shell” Eisenberg, of Kona, Hawaii broke the USA Women’s National Freediving Record in the discipline of Constant Weight (CWT) on Sunday, May 13, 2018, with a dive to a depth of 85 meters (279 feet) below the surface on a single breath of air. Eisenberg’s record dive occurred on the final day of the 2018 Deja Blue International Freediving Competition taking place off the coast of Grand Cayman and took 2 minutes and 51 seconds to complete. The previous record of 84 meters was set by fellow USA athlete Ashley Chapman off the Dutch Caribbean island of Bonaire on September 6, 2016.
 
In the competition freediving discipline of Constant Weight (CWT), as recognized by Association Internationale pour le Développement de l'Apnée (AIDA), the sport’s international governing body, an athlete takes a single breath on the surface and then kicks themselves down to depth, usually using a monofin. The athlete follows a safety line and any weight the athlete wears must remain on them throughout their dive.  
 
This is Eisenberg’s first depth national record.  She has also held two USA national records in the pool discipline of Dynamic No Fins (DNF), in which an athlete swims underwater for distance in a pool on a single breath of air:  125 meters (410 feet) set in Grand Cayman 2015 and 132 meters (433 feet) set in Kamuela, Hawaii in 2016.   
 
“I’ve been training hard for this record for a while now and I can’t believe it all came together in the 11th hour on the last day of the competition. Although I have to perform the dive myself, a successful result like this takes dozens of supporters, including safety freedivers and rebreather divers, surface coaches, training partners, and more. I couldn’t be more grateful to everyone who helped me reach this new depth—it’s beautiful down there!”   Shell lives and trains in Kona, Hawaii, where she teaches freediving through Performance Freediving International (PFI) and is an artist.  
 
Eisenberg’s record Constant Weight dive ranks her among the top 20 deepest women in history.    “Shell is one of the brightest stars in USA Freediving right now and she’s put herself in position, through a lot of hard work and discipline, to achieve a lot more in our sport” said John Hullverson, President of USA Freediving. “Shell’s 85 meter dive was incredible on so many levels. Not only was she able to withstand the nine atmospheres of pressure her body was under at that depth, but for her to endure the hypoxia, increased lactic acid buildup in her muscles and
urge to breathe throughout a nearly three minute dive, and then complete her surface protocol so cleanly, is a testament to what kind of shape she’s in. I don’t think we’ve seen the last national record for Shell!”
