The FourPro is a salt-tolerant underwater housing for the iPhone 4 and 4S, which allows the phones to shoot undersea video at depths down to 100 feet
If nothing else, the iPhone 4’s ability to shoot 1080p high-def video has certainly done one thing – provided inventors with things to make. There is currently what could almost be described as a gold rush, as products are being designed to augment the smartphone’s camera, to the point that it could be used for all of the same things as traditional, stand-alone video cameras. Some of these innovations have included interchangeable lenses, a mini SteadiCam, and a rugged helmet-mount system. Now, an underwater housing system for the iPhone 4 and 4S is in the works, which will allow users to shoot undersea video at depths of up to 100 feet (30.5 meters).
