This is a more affordable and awesome alternative to the GoPro. This Hitcase Pro is a wide-angled waterpoof case for iPhone 5/5s.
It's compact and 170º lens triples your phone camera's effective field of view, so you can get more of your videos and photos. It also comes with a compatible mount. Great for outdoor use as it has a ShockSeal design of rugged ABS, polycarbonate and medical-grade silicone - all of which will protect your phone from the outdoor elements.
