This is a Backscatter Flip 3 color filter device, mounted on a waterproof scuba diving case for a GoPro Hero 3 on a Backscatter handle/tray. The device consists of a filter that flip into place over the camera lens when diving in depths of 40+ feet. I've used this on several diving trips and it works great! Super simple to use. You just flip the filter into place and It makes those otherwise dull blue/green underwater videos have bright coral and fish colors.
The rear panel has a couple of small scratches on it, but doesn't impact anything.
The Backscatter Handle & Tray allows for steady shooting underwater with your Go-Pro Hero 3.
Lens cover included to prevent any scratches on the filter.
