Science has discovered that corals contain fluorescent proteins that are invisible to the naked eye and jump into view using innovative high-intensity fluorolights and filters. Big Blue Fluorodive kits provide everything you need to experience this stunning effect. You get specially designed filters to precisely match the coral fluorescence wavelength and yellow-blue barrier filters to increase the intensity of the colours emitted by the corals. Our innovative design is the only one that allows you to easily switch between blue and white light to accommodate changes in dive conditions. These kits are suitable for night divers, resorts, science institutions, ecological monitoring groups and speciality photographers.
