So you want to use your GoPro for deep water shooting. I have a bit of bad news for you. The housing that comes with it doesn’t really work very well for deep water shooting due to the round shape of the lens port. In order to get focused shots, you are going to need a flat port on that little housing. Still good all the way down to 130′, the Backscatter Housing will also accept different types of filters. If you are diving with your GoPro Hero 2, this is a necessity.
