Right then, the dotting and dabbing lads have lost my 3 core and earth wire inside a wall for me. The wall is quite thick as it is on the outside wall of a barn, so there is plenty of space for my cable to get lost in. How can I find my cable? I have tried my cable/stud finder on it, but it only goes to about 12mm deep. Someone mentined putting high frequency on it, but I don't know how to do that.
