22. Making a Fluorescence Dive
• Night
• Use your white light to navigate and orient yourself
• Switch over to blue light, make sure you have the
yellow filter in front of your eyes
• Use your white light only as needed to:
– Re-orient yourself
– Signal your buddy (they won' t see the blue!)
– Find out what it is that is fluorescing
• Etiquette – don' t point your white light where your
buddy or other fluorescence divers are looking
• Discover a new world
