DiscoStu said:A Go Pro is ok but it is a very wide angle. I have a Hero 4 and that does have some less wide options but still pretty wide. I also have a Panasonic Lumix camera that is a compact digital camera designed for active people (so not sure why I own it!) it is water proof and the quality of the images are stunning. I'm very fussy about image quality and can tell you which lens I've used on my SLR just from the image and the Panasonic really is brilliant.
I have one of those, used it on a bunch of water slides back in the 00s. Shame it sits on a shelf now, as you're right, really decent quality HD videos and images can be had from that bad boy.
