SCUBA

Last night I took a basic SCUBA refresher class. We covered such topics as hand signals to communicate underwater, entry/exit, buoyancy control, equalizing the ears, mask clearing, air share, ascent/descent, planning with a NAUI Dive Table, emergency swimming ascent, and treating nitrogen emergencies.

I first became certified in college by taking diving as a phys ed class so I could dive in Jamaica. We did a night dive in Sponge Garden in St. Anne's Bay. Note: the sea critters, ie., hydras and jellyfish, are attracted to light. Bear this in mind if placing a light near the ladder to board the dive boat. Our divemaster was stung about the face as he surfaced.
