The Zircon StudSensor Pro 25 provides reliable edge detection for wood and metal studs up to 3/4" deep behind drywall. A light indicates when calibration is complete, and an illuminated arrow shows when a stud is found. The V-marker groove on top enables accurate pencil marking right at the stud edge, so you can hang shelves, TVs, and heavy items with confidence.
