The DEEP+ Bluewater Color Correction Red Filter from Flip Filters mounts on the top or side of your GoPro HERO (compatible with all models from HERO3 to HERO13) as a second filter. Designed to counteract the effects of the ocean on light, this filter absorbs the red wavelengths at depths from 45 to 80' and facilitates accurate color reproduction for your footage.
For underwater photography from 45 to 80' beneath the surface
