How often do you take an action cam underwater? Most people never will, and YI clearly thinks that scuba divers will be happy to stump up for a waterproof casing whatever brand of action cam they choose. So in some regard the YI 4K ActionCam is about some cutting corners, but what it leaves out – GPS, voice control, auto-upload, and raw shooting – are hardly core features. In fact, it gives as much as it takes, with a large and responsive touchscreen, a big battery and a fast file transfers all good reasons to consider the YI 4K.
It may lack a few niceties – and we would include lens distortion correction and image stabilisation in that list – but the YI 4K Action Cam remains a great value addition to any adventurer's kit bag.

The Hero5 Black is a great reminder of why the name GoPro is so revered and why it's still our top action camera pick. Simple to use, the addition of a rear touchscreen, voice control and GPS make it one of the most feature-packed cams currently available.

If may lack GPS, voice activation and the ability to link external sensors, but for those who simply want to capture good-looking footage without breaking the bank, there's very little to complain about.
