I just got a Hero 3, and don't really want to mount it off my mask or shoulder, but would like to have it on a long leash/tether that I can attach to BCD ring than store in BCD pocket when not using. Anyone do this and have pictures? Or know of any tether/leashes that are being sold for this type of use? Also any other ideas or practical applications i'm not thinking of, for someone that wants to use it as more of a "camera" and only shoot partial video during a dive?
