I have a standard GoPro...never been used other than to check its working, still have the wrist strap and its still in its clear acrylic case. Also have a couple of wireless versions where a small unit
(size of an OXO cube?) goes in the car and you connect the receiver to a video camera or whatever....
Would be interested in a trade for a bog standard Mardave.
Like I said...I have a couple of these things if anyone else is looking for some on-board video?
