The Xtreme Action Series 5-Piece Underwater Filter Kit from Bower is designed to work with the Xtreme Action XAS-WPH underwater housing for GoPro HERO3, HERO3+, HERO+ LCD and HERO4. Each filter provides color correction for specific water depths and temperatures, replenishing vibrancy and true-to-life color balance for your video capture. This kit includes five scratch-resistant, high-grade filters that easily press into place and a neoprene case for easy transport. The Magenta Filter provides color correction for greener water. The Yellow Filter is used in shallow (<35 ft/10m), bluer water for exceptional color correction. The Grey Filter reduces bright light to curb overexposure in very sunny conditions, akin to a light neutral density filter. The Red Filter provides color correction for dives beyond 35 ft (10m), replenishing the red light absorbed by the water for more vibrant image capture. The Pink Filter provides milder color correction for shallower water (<35 ft/10m) and also enhances sky, clouds, water, foliage and snow.
