Works, but super short range – Free Metal Detector - Stud Finder and EMF Meter in One! Review

It works exactly as they say. It’s super short range, and remember, this only detects metal and EMF fields. Even shows how close to WiFi and speakers you get. To find a ring or something would take a long time, but could work.
