Dear bluemar
Herbert Nitsch, current world-record holder and fellow-Austrian has pointed me to the brilliant contributions of Eric Fattah on the internet, that have helped him achieve his records.
So take a look at Eric's treatise on the Frenzel/Fattah-technique:
http://www.ericfattah.com/frenzel.doc
I had the same problem as so many freedivers have! No air left
to equalize my ears - and I have an urge to communicate to You
and to any other person who happens to bump into my message -how much the observation of this technique has helped me - because it is easy to learn !!!!
To re-explain Eric's method in my own words: You close the epiglotis and SHUT OFF THE CONNECTION between your mouth and your lungs. As pressure increases You push up pockets of air into Your mouth (squeeze them through your otherwise closed epiglotis). You begin about 15-20 mt before failure depth and continue to do this as long as you can. The simple trick: The air is trapped in Your mouth and the empty - almost negative lung cannot take it back. With this trapped air (Your cheeks should be inflated) You do a Frenzel-technique (press the air into Your ears without the help of the lungs).
My personal testimony:
My failure depth used to be -35mt (couldn't do equalizations past that depth) allowing me to cheat my way further down to a maximum of -40 to -42mt, depending on my shape for that day. I did the first austrian national record that way in sardinia in '98. (-42mt)
I went down with the uncertainty to reach my goal - even though there was enough air to go deeper!! I hope, many freedivers can identify with me in this situation. Fortunately I reached my goal that day but my ears were bulged inward and started to hurt already. But with the Fattah Method I can equalize now at a depth of -45mt WITHOUT packing my lungs and with a "normal" Cressi Sub Super Occhio mask.
The reason why my progress is still slow is, because I have only my wife waiting for me at the surface (who is not a freediver).
Astoundingly it's pretty hard to find an apnea-buddy inspite of all the organizations out there, therefore I am glad that I found this forum ...
