Meet the FLIP4 Pro kit for GoPro cameras: a 3 filter kit that lets you flip between filters on the same dive with a simple touch. FLIP is tough enough to survive abuse as it is made using aircraft grade aluminum and unbreakable filter optics.
The kit comes with shallow, dive, and deep filters. You can mount any 2 filters to your GoPro at the same time. FLIP fits standard and dive housings for GoPro 3/4. More information is available here.
