Over the course of my career as a dive instructor I've witnessed a few students injure their ears on descent or on ascent. It's a painful experience for the unfortunate student who ignores the increasing pressures on the way down or tries to force an equalization that just won't happen.
PADI Open Water course materials highlight and emphasize the importance of full and proper equalization of your ears on descent and what to do in the event of a reverse block on ascent. At VSDS, we think that every novice diver ought to have a full medical and physiological understanding of what's going on in your ears when you dive.
