Has anyone used I3S Manta or I3S Contour for photo-ID assistance, specifically with humpback whales? It appears to have worked successfully with whale sharks and manta rays. I am interested in using it and/or testing it out, but I was wondering if anyone out there had any previous experience with it. If so, I'd like to hear how it went for you.
