Three BIG advantages you'll appreciate: 1.) Film longer. Sony's rechargeable battery lasts 30-40% longer than the GoPro and others. Wonderful + for day-to-day riding. 2.) In and out of waterproof case much faster and easier. Latch mechanism easier to manipulate. A difference you'll enjoy over, and over and over. 3.) Lens-case orientation better for many kinds of mountings. Helmet side mount, fork mount, etc - The Sony front-to-back lens-body design is lower-profile and easier to position for many kinds of POV shots. Otherwise, many similarities to the GoPro Black system. Features a full HD 1080p with Steadyshot® image stabilization, captured through an ultra-wide 170-degree view Carl Zeiss lens. There's also a large glove friendly press-n-go start/stop button.
