Milwaukee M12 2290-21 sub-scanner detection tool
By Anthony Capkun
Milwaukee expanded its Li-ion system with the M12 cordless sub-scanner detection tool. The 2290-21 can detect rebar up to 6-in. deep in concrete, as well as the location and depth of materials beneath gypsum, ceramic tile and marble. It detects the location and depth of wood, AC wiring, PEX, PVC and metals. The tool was designed with a four-wheel design for smooth measuring, and boasts an ergonomic handle position for ease of use and a high-contrast, white-on-black display for clearer readings.
