Not being the greatest of fans for previous Gopro cameras, this Gopro 7 Black is much better and stronger than previous. The greatest advantage is the camera is itself completely waterproof and no housing is required (although an option if required). No housing means no fogging and condensation building up. Otherwise Gopro's reputation speaks for itself.
One feature of this camera is voice control which I was trying out close to the sea, it worked well but I didn't hear someone out walking approaching me from behind, and there was I talking to my camera, never again.
On the plus side, I won a Gopro award for the film below which also went viral when posted by Aquabound on facebook.
