Although obvious, I put this here first because this is one of the most important factors when purchasing your camera. The HERO3 has three editions (white, silver and black), ranging from $199 - $399 (prices continue to drop annually as newer versions are released -- we'll keep you updated on those). The HERO2's are at the bottom of this gap, but aren't as "new" and lack some features the 3's have (they're discontinued at this point but can be found on the net here and there).
The GoPro Hero 5 is a fantastic underwater camera. However, there is a catch. The device cannot submerge on its own. Rather, it requires a Super Suit Dive Housing (also from GoPro) to get wet. Even so, that accessory turns it into one of the best diving cameras around. The device is able to go down to 196 feet and comes with a bright 2-inch touchscreen display that is easy to use while swimming. The ultra-wide angle lens, 4k recording capabilities, and 12MP image resolution bring it all together.
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.
How do I download GoPro app to my computer?
You get many of the same shooting modes you'd find on a GoPro device, such as time-lapse photos and videos and slow motion footage at 1080p at 240 fps, and there's even a Drive mode so you can use it as a dash cam when plugged into your car, automatically turning on when you start your car and off when you stop it. It's not waterproof on its own, but a dive housing is included as well as several mounts, two batteries and a charger that simultaneously powers up both packs. It also has built-in Wi-Fi so you can connect to a smartphone and use an app to control the camera and transfer your shots for sharing.
