This 55mm Threaded Underwater Color Correction Red Filter from Flip 4 attaches to your GoPro 3, 3+, 4, 5, 6, or 7 using the Flip 4 55mm filter holder (not included). It is meant for use in blue ocean waters found in the Caribbean, Bahamas, Indonesia, and others. The red color of the filter counteracts the effects of the ocean on light, which absorbs the red wavelengths and restoring color to your footage. It is made from aluminum with an acrylic filter and attaches to 55mm filter threads.
