Dewalt's existing 12V MAX Lithium Ion system now benefits from the addition of the Hand-Held Radar Scanner, No. DCT418. The tool detects and identifies wood, ferrous metal, non-ferrous metal, live electric wires and PVC behind multiple types of wall surfaces making it ideal for remodelers, installers, service technicians and maintenance personnel. This tool can scan through wall surfaces including vehicle interiors, drywall, plywood, concrete, marble and ceramic tile at a sensing depth of up to 3". Includes a 3.5" LCD color screen and a pre-scan mapping mode that eliminates the need for the user to calibrate or choose between settings.
