Red filter designed for celestial waters for the GoPro Hero 5 Black camera (without waterproof case). Used mainly when recording underwater movies in blue waters, it allows for better white balance and eliminates the excess of green and blue in the material being recorded. Made of scratch-resistant glass. A cover included in the set. The installation does not require any tools (press-in). Designed for shallow and moderately shallow dives - from 1.5 to 10 meters.
