On a night dive in the Philippines several years ago, I had an opportunity to do a "fluoro" night dive. Atlantis Dive Resort rented blue underwater flashlights and yellow filter shields that went over divers' masks. Geared up, I set off into the night. The blue light was very dim and the dive was much darker than a normal night dive.
You just have to do it to understand it. Until you have experienced it, the name itself does not stir the emotions as much as the other types of diving. Once you have experienced the treasure hunt for yourself, you will be hooked. Marketing specialists would agree that it is probably misnamed and they have even tried to rename it, but nothing has stuck the same way as the coined term “muck diving.”
It was seven in the morning and my coffee hadn’t kicked in yet. The dive guide was giving me a slightly more thorough dive briefing than normal. I wasn’t supposed to wear anything colorful or shiny, and black gloves and a hood were required. Also covered in black neoprene, he was putting on chainmail gloves and told me he’d have a pole with him. He said it was more for the potato cods though, not the sharks.
