[...] to blackout, no matter how good of a diver they are. I blacked out last week. Freediving great, Patrick Musimu died last year because he trained by himself in a pool. It happens, so the best plan is to employ a [...]

But she was coughing up blood! That can't be good, I was shocked that they took it so lightly. I would have asked to be checked out in hospital.

The people that need to learn a lesson is Omer - this diver was was trapped because of the stupid clip they put on their Stingray footpockets (and the Millenniums had this unnecessary clip too, though the Stingray design is worse). How they could not consider the risk is unbelievable.  No other footpocket design includes anything that line can catch on.

the diver is feeling fine after a minute under water with a 1/2 breath, then the next thing is hes panicking because...hes out of breath completely!!! (hyperventalation?)Always surface well before you absoultely need to, with about 15 seconds to lesuirely get up. That way, if you find yourself stuck, you have time to assess and release if tangled. If that doesnt work, cut the line immediately with no hesitation. Lines are super dangerous anytime, especially in murky, kelp heavy water.

Lesson learned: no fish is worth dying for! If you're trapped underwater and you need to breathe, get your knife and cut through the line. I have been trapped underwater once by some fishing line that got tangled around my weight belt at 6m, and I was amazed at how calmly I reached for my knife and cut myself free.
