Quote:
As you point out someone that loses consciousness due to shallow water blackout may be restored (with limited stimulation on the surface) AS LONG AS they don't have water in their lungs. That alone could cause death otherwise. The snorkel apparently maintains an open pathway that defeats the closing off of the breathing way that usually happens automatically without a snorkel in place. The course goes into shallow water blackout symptoms, signs, detailed techniques for avoidance, emergency retrieval, restoring procedures, etc.. Lots of good content derived from accident experiences in competitive free diving. It takes a lot of the randomness out of free diving particularly diving with a buddy with similar training who knows what to look for and how to react.
