DeWalt is adding a Hand-Held Radar Scanner to its 12-volt Max lithium-ion system. Using radar sensing technology, the tool detects and identifies wood, ferrous and nonferrous metal, live electric wires, and PVC behind wall surfaces, then displays the detected objects on a screen. It can scan through drywall, plywood, concrete, marble, and ceramic tile at a sensing depth of up to 3 inches. It will be available in May for approximately $300.
