purchased to search for electrical son behind a partition plasterboard (the wire was put between the wall and the rail), impossible to find. Test to check whether the device works well: - Detection of apparent wire with a plug 500watt spot on the line, the device detects about 4 cm. - Same test but thread behind the plasterboard BA13: detects if the wire is plated plasterboard. about 1.5 cm. Iron detection: Detects an iron bar was about 10cm of concrete and welded mesh in the screed under tiles without cares. On this point nothing to say. Detection drink this has operated air. In summary very good device to detect iron.
