I covered 4 miles today... Not much for sure, the reason was to try out a different GoPro arrangement.. I bought the camera to record some of my favourite roads though the wind-rush picked up by the mic drowned out the sound of everything else, which was less than desirable, so I bought the kit to allow me to fit a remote mic with a sock so wanted to try it out in a number of locations to determine if I could make an improvement on sound quality, pleased to say it worked out rather well... Hoping now to cover a few more miles on my next time out... (-:
