Maybe I dreamed this, but I'm sure I remember seeing advertised a gadget in two parts which you could place either side of a surface to show you where a drilled hole will exit on the blind side. In case I haven't described that very well, you would have someone hold one half of the tool at the point where you intend to drill, then you go round the other side with the other part of the tool and move it around until it indicates, by light or sound, the point where the drill is going to exit. Anyone know what I'm talking about? Thanks
