Night diving completely transforms the underwater world. The reef you explored during the day looks entirely different; diurnal fish are sleeping in crevices, while octopuses, lobsters, and bioluminescent plankton come out to play. Here's how to prepare for your first dive in the dark.
Bring a backup light. Two lights are always better than one.
Don't shine your light directly in your buddy's eyes—use hand signals illuminated by your beam.
Take it slow and focus on the macro life you miss during the day.
