George,

What happens when a sheep flies over your head? Does the air pressure
increase to the point where it ruptures your ear drums?

Next time you find yourself bobbing up and down in the ocean sucking on your
80cf bottle of 80/20, push your colored regulators, poodle jackets and
bungie wings aside and watch your depth gauge as a wave passes over your
head.  When the numbers do not change, what does this tell you?

BTW we are very interested in just exactly who or what provided your
socalled "technical" dive training. Did some or all of your classroom time
take place in a barn or a shed?
