Look at what deal i missed out on...
The Optrix XD5 Waterproof iPhone 5 case, along with a monopod, has allowed me to film swimmers during lessons and in workouts, with more ease and clarity than I've experienced with any other products. Period. This inexpensive combination of products gives me the ability to "track" swimmers better than anything I've ever used. The "magic" of this case is the wide-angle lens on the back of the case. It's like having an Olloclip on your phone, but with a waterproof case. With the Optrix combination, you're now able to shoot video of your swimmers in Lane 1, and get the entire body in the frame.
