It can take a long time to get an up-to-date response or contact with relevant users.

That's why it is best to take a series of structured courses. It's better to learn the different steps in the order they are needed. As Azrael3000 mentioned, there is a difference between methods of blocking air movement and an even bigger difference when you have to block air from leaving the lungs and from entering on the same dive. Some instructors would rather teach packing after you've learned the changes required at 30-40 meters. Maybe they shouldn't teach mouthfill until way later and save some divers from hurting themselves. There are many things that are easier to learn with an instructor.
i still not understand very well: did you mean "more useful" or "more useful than something"? if second, what is something? thanx
Oops. Didn't mean to coin a new phrase or anything but if you use a tongue block to keep air in your lungs what would you use to keep air out of your lungs? Anyway the less you have to think about using the tongue the better.
By more useful, I meant learning in the same sequence that techniques will be used. Seems to be very important to some instructors. Sort of........ first you learn to crawl and swim, then to walk and run, then comes the bicycle......and so on.

Hi there!
Since the topic matches my problem somehow, I won't start a new one. :t
Unforntunately I got my trachea squeezed again yesterday, because of having contractions while trying to equalize. My contractions are already starting if I get below 12-13m and my adam's apple starts moving involuntary like crazy. I tried different breath-ups a.k.a. more or less hyperventilation and it's almost the same everytime. Even with eyes closed, chin tucked in (which helps me in dynamic to delay my contractions quite a few meters) it's always the same. I'm guessing it has nothing do with a real urge to breathe after such a short time. According to two instructors my duck dive and finning is pretty good. I'm a bit lost here, what else I could try. Do I just need more time to get used to the pressure?

I added a few purges to my preparation and did a bunch of variable weight dives to 40-50m. that helped a lot, deeper dives got more relaxed and comfortable. We were pulling the line up 20m before the dive, and I was holding onto it for the first 20m and then freefalling for the rest. Ascents were either FIM or finning up.
