Bigblue FDK38 Fluorodive Kit

The FDK38 Fluorodive Kit from Bigblue is designed to help view fluorescent coral and fish. It includes a blue filter and a yellow blue-barrier filter mask. The kit is compatible with several Bigblue dive lights including the CF450, CF1200P, AL1200WP, AL1200XWP, AL1200WP Tail, Black Molly II, and Black Molly III. The filters allow observation of underwater organisms that have fluorophores in their proteins which are invisible to the naked eye but visible with the provided filters.
