To get right to the point of my writing: I can't give you a definite answer. What I can definitely tell you right now is that we are to focus on the GoPro HERO4 and HERO3+'s (and I will touch base on a few HERO2 and original 3's as well), as it is the best technology and provides options for numerous consumers. With the recent announcement of the HERO4's especially, we'll tackle the main features of those to help you decide if that hefty price is worth it.

For a company known for its camera drones, DJI got a lot right with its first action cam. One of its stand-out features is its front color screen. It might be small, but it's enough to make sure you're centered in the shot when the camera lens is facing you. The view can be switched with a voice control. It's also waterproof and rugged with removable lens covers, it has great electronic image stabilization, shoots HDR video and has customizable presets so you can get to the shooting modes you want without diving into menus.

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.

The GoPro HERO7 White is the company’s entry-level model, although the term “entry-level” is a little hard to apply to a camera so powerful. The HERO7 White has most of the same features as the other HERO7 models, with one big difference: the camera is limited to HD (1080p) video and doesn’t shoot in 4K. That’s not as big of a deal as it sounds. The resulting video is still excellent, and the price break more than justifies the concession in resolution. The GoPro HERO7 Silver is another good option for anyone looking for a good middle ground between the HERO7 White and HERO7 Black. It records in 4K at 30 fps, and it even has on-board GPS like its more expensive counterpart. If you need a dependable, affordable 4K camera and you don’t mind that the battery isn’t user-replaceable, the HERO7 Silver is your best option.
A. It depends on how big of a memory card you use with your GoPro. GoPro cameras work with standard SD cards, which are affordable and come in all different quantities. In most cases, it pays to get a memory card with plenty of storage. GoPro videos, especially those shot in 4K, can produce especially large files that can eat up storage faster than you think. We recommend getting an SD card with at least 128GB of available storage.
