Lets flesh out this work in progress a little....First, take a class.

Regarding Safety Procedures: There is more to this than meets the eye. For example, what is a laryngospasm and how do you release it? What is the appropriate head position for an unconscious diver when you bring them to the surface? How do you protect their airway? What do you do when a diver Sambas or blacks out?

My point is that Akoni is offering a useful outline but practical instruction is critical. So take all this information and keep it in mind when you get into a class. Simply reading it doesn't mean that you know it or understand it.

Bouyancy:
Freedivers try to be neutrally bouyant at 10meters (33ft) so weights should be calibrated accordingly.

Descent/Ascent Rate: Once a diver is negatively bouyant he strives for a sink rate of 1meter per second and the same rate on ascent.

Surface Interval:
Evidence suggests that adequate surface intervals are required to avoid asymptomatic nitrogen build-up.... a common rule for surface intervals is: for dives above 25meters, two times the duration of the previous dive and for dives below 25meters, two and a half times the duration of the previous dive.

I am sure I can come up with plenty more...
