Guided Sport Dives

Fluorescent UV night dive
Fluorescence night diving is also referred to as fluo diving or glow diving. Fluorescence absorbs high-energy light and  re-emits it as low-energy light. This is different from phosphorescence which has the capability to store light and re-emit it over a longer period of time.
When glow diving, UV flashlights and lens filters for your mask enhance the stunning colors and unbelievable beauty of the underwater world. All of the critters and corals that you swam past earlier will be worth a second look as they glow in hues of pink, green or blue.

Bioluminescent Ostracod night dive
Come night time, bioluminescent ostracods live up to their name. Displays begin during the first truly dark hour of the night when no moonlight is present, typically about 45 to 50 minutes post-sunset, after sunset. During this time, male ostracods leave the reef and swim up into the water column and secrete an intricate series of long-lasting pulses of light to attract non-luminescent females of the same species. These coded trains of pulses serve to attract the same species of females’ attention in hopes that at least one will approach the male, allowing for successful mating.  The train of light can be produced vertically up or down or diagonal, depending on the species.
Sudden in the darkness  the string of lights started appearing on the reef and before you know it, the lights were everywhere. It’s so beautiful, like your looking at the stars. Some customers said, ” just like the movie, Avatar.” This is an experience that you would never forget. After you have enjoyed the light show, we continued on our normal night dive.

This special type of diving requires divers to be comfortable with night diving and the particular skills that are needed for such dives. While the glow illuminates the surrounding area and divers have flashlights, there are still many safety concerns that divers need to be prepared for before taking the plunge.
