I have a contour
I want a Go Pro but holding out for the 960
Contour is just too limited on mounting options and weatherproofing to make it any good for MTB in my opinion
Helmet mounts – tricky to fit flat plate / velco straps on a curved vented helmet and therefore wobbly footage
Stick on mount – flat and cant really go anywhere other than a pisspot lid unless you have huge tubes on your frame
Handlebar mount – badly designed impossible to tighten with gloves and puts camera too exposed above the bars, also camera on handlebars Im not keen on as the slightest direction change looks like a huge jump in direction
The cradle that lets you use a standard camera fixing is good, but then you need additional mounts as well, I ended up making my own frame mounts to attach it to seat clamps and bottle cage bosses but then the camera is again exposed and the last thing you need is mud and grit in the sliding record switch (easy to operate but very tempermental once dirt has got in)
Only thing the Contour has going for it is the rotating lens and sighting lasers, both of which with better mounting options I could do without
I now only use it on my helmet, any other places, its not weather proof enough to cope
If they did a chest mount though….
The Go Pro chest mount is by far the best mounting option, the lens is a wider angle, the waterproof case is miles better and the HD footage seems comparable
I second Dogcamsport as a good source of info
