See your favorite site after dark. Night diving turns a familiar reef into a brand-new world, nocturnal life out feeding, bioluminescence in the water, your light beam leading the way. The SDI Night/Limited Visibility course trains you to dive it safely: lighting and backups, buddy contact in the dark, navigation without visual reference, and low-light emergencies. It counts as a specialty toward your Advanced Diver rating. You'll need your own mask, fins, boots, and snorkel, plus a primary and backup dive light, and the rest of the rental gear is included.
