    Kingsdale bore

    I surfaced once from Joint Hole directly into the path of a passing Chaple-le-Dale bore. I was worried I may get washed down into Aquaflash Pot, or over Gods Bridge, but managed to drag/float my way to the side of the beck, and grab some turf ! Witnessed by two amused fellow divers.

    Replacement Aladin dive computer batteries
