Capture accurate colors underwater with your HERO4, HERO3+, or HERO3 camera. This B+W Underwater Kit includes a red filter, a magenta filter, and a 58mm filter mount for the standard housing of the camera. Compensate for the color cast caused in water once you are under several feet of depth. The red filter is for blue and tropical waters, and the magenta filter is for green and salt waters. The filters feature a hinged frame that allows them to be quickly removed when you want to use the camera out of the water.
