“Difficulties in identifying corals underwater have been hampering coral enthusiasts and researchers alike for decades. I feel that the Coral Finder is a huge leap ahead. It is exceptionally well designed and easy to master. It is also timely, as the need for accurate survey has never been so pressing. I strongly endorse it for use anywhere in the Indo-Pacific.”
Prof. J.E.N. Veron
Author Corals of the World, former Chief Scientist of the Australian Institute of Marine Science
