3-in-1 Handheld Detector Wall Scanner Stud Finder Metal AC Cable Wire Detector Handheld Multi-Scanner with Buzzer Sound Warning and LED Light Signal Indicator Wood/Metal/Plaster

This product only works 50 percent of the time

item arrived next day , used it later that day, worked ok to a limit, its says it will detect wires up to 19mm deep, would only work at 13 mm, any deep does nothing, but ok for what i need, and cheap

Great
