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.
Though the Hero 8 Black has all the latest and greatest features, in the end it's not a huge leap forward from what you'll get with the less expensive Hero 7 Black. It's last year's model and has almost all the same features -- including HyperSmooth image stabilization, the killer feature for this model. There are a handful of other differences like a better user interface, more shooting options such as 1080p at 240 frames per second, vertical video and livestreaming straight from the camera. That said, the differences between the Hero 7 Black and discontinued Hero 6 Black aren't that great either, so you might want to keep an eye out for deals on that as the holidays approach.

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!
