Summary
4.2 stars, 1,800 reviews. The LCD screen shows scan depth and object type. Radar-assisted detection works better on difficult walls than capacitance-only models. Runs on DeWalt 12V batteries, which is convenient if you own 12V DeWalt tools but adds cost otherwise. Mixed reviews on reliability; some love it, others get inconsistent readings.
$80-120 Home Depot, Amazon as of April 2026
