Although not necessarily the most important component, a defining element of a GoPro is its lens. Rather than using a standard lens, GoPros — like many other action cams — use an extremely wide lens. What this does is increase the amount of scenery you capture in the frame, making it easy to frame your shot. Mount it to your handlebars or the side of your helmet, and you can rest assured that it sees just about anything that happens in front of you.
GoPro cameras are known for their premium shooting capabilities, but not all of them hold up underwater. Some options are a bit blurry, while others lack great depth. Always ensure the GoPro you take diving is able to shoot as well underwater as it can on land. A bit of quality difference is not the end of the world, but you want your videos to be as clear as possible.

Also note that their newest line of cameras, the HERO3+ (plus) are only smaller in size and lighter in weight. As of now, the Black Edition for both Hero3 and Hero3+ are only a few dollars different in terms of price, so go for the plus! And now that the HERO4's are out, check the prices of previous versions as they'll be dropping slowly. Unless of course you want the newest of the new, check out their HERO4!

Image quality, while good for a small action camera, is another area where a camcorder or interchangeable lens camera will come out ahead. Mirrorless cameras and DSLRs use significantly larger imaging sensors, which capture more light and thus lead to superior image quality, particularly when you have to shoot in low light conditions. But even small-sensor camcorders benefit from built-in zoom lenses, which offer a variety of perspectives without cropping the image, as a GoPro does when selecting narrower fields of view.
What comes with the GoPro 7?
GoPro is leading the charge toward consumer-created virtual reality (VR) environments, and their first VR-ready cameras make it happen with what they’ve dubbed “spherical capture,” which is pretty accurate, given the 360° field of view they record. VR is still a nascent technology, but it’s definitely the future. If you’re an early adopter, you’ll want to pick up a GoPro with spherical capture.
