I have a length of two Ethernet cables running upwards from a socket. I vaguely know where they are (+-10cm), and I want to fix a Vesa mount to the wall near their route, so i need to trace exactly where they are, so I won't drill through them.
What would be the best way to find them? Cables are run under plaster, on a brick wall, and since it's freshly finished,I really want to avoid digging them up.
I thought of connecting 230V to them, and use normal wire detector, but there has to be a safer way to do this.
