Hello to all fellow freedivers! 
I have a question about the frenzel equalization technique, I realized that in order for it to work for me, I had to use valsalva to clear open my ear drums first in the surface.
If I were to try the tongue "piston" before opening my ear drums with valsalva it doesn't work...
I'm not sure if anyone here is experiencing the same thing? Am I doing it right/wrong?
Any input will be greatly appreciated...
