Free Diving...aka Skin Diving!

[Islandtrader]

This thread is to find out a little more about diving with out tanks.

Connor I know you are a free diver...are there any more of you around?

My few questions are what is the average depth you normally dive at, and how long can you stay down?

Did you have any specific way of training yourself (lung capacity)? I am certified scuba, but my personal MO is scuba is just to much stuff to haul around. So diving fell off my radar. Looking for another way to use the 21?

Any thoughts or books or articles that anyone can recommend.

Thanks,
