Is it the actual lens on your camera that ' s scratched or is it the lens cover on your waterproof housing that ' s scratched ? Those are two different things and require two very different repairs . I ' m going to guess your lens cover is scratched , based on the pic in your post . In this case you can order a parts kit from GoPro , eBay , Amazon , etc and do the repair yourself in about 5 minutes . It involves taking off the lens cover by removing four hex screws inside the housing , then putting the new one in place and replacing the four screws . Done . Certainly not rocket science . If you want someone else to do it , you don ' t need to bring your actual camera with you and it can be left at home . <| sep |> Oh dear ! Haha . That one of the quick release pins then or the ones that hold the links in ? If so then you get replacement ones with it anyway
