Is it the same technic that from the movie "Into the Blue"? Those ppl can dive into underwater for few meter with mask and fins only. Any requirement for the diver and the environment to do the free diving? I thk at least the visibility should be very clear.
And i saw the record from the website given, someone can do breath holding for 8 ~ 9min..... wow, they really great.
I think I cant last more then 60 seconds inside a pool.....
but seriously, how to dive or get into the bottom of the pool.....lets say i want to try n dive + test how long i can stay underwater....
any methods + training ourselves at public pool?
normally i go to the olympic size pool > i try to dive.....>but i keep floating to the surface

whats the correct technique? hold my breath?
