One filter is not enough. We've made thousands of dives to determine the best filter formulas for all diving depths. This 3 Filter Kit is your simple solution for perfect color. Flip between any 2 filters on the same dive with the touch of a finger. FLIP5 is designed to survive the drops and abuse that we regularly give our own gear. With aircraft grade aluminum and virtually unbreakable filter optics, we're confident you'll find that the FLIP system delivers the most rugged design along with the world's best color for GoPro.
