Key item features

  • ACCURATE STUD DETECTION – Detect with Confidence: Reliably finds the edges of wood and metal studs up to ¾ inch deep for secure mounting of TVs, shelves, and cabinets. The precise scanning helps minimize surface damage and ensures every installation is solid and level.
  • ADVANCED WIREWARNING TECHNOLOGY – Smart Safety Scanning: Instantly alerts you to live, unshielded AC wires up to 2 inches deep to avoid drilling into electrical lines. This smart safety feature makes the tool essential for any project involving walls that may conceal electrical lines. A must-have wall scanner and wire detector for safe, accurate work.
  • EASY-TO-READ DISPLAY & AUDIO INDICATORS – Know Before You Drill: Alerts you instantly to live, unshielded AC wires up to 2 inches deep to prevent accidental drilling into electrical lines. Whether you’re working in a brightly lit room or a dimly lit space, the display ensures quick, confident readings every time.
  • ERGONOMIC & DURABLE DESIGN – Built for Comfort and Control: Designed with user comfort in mind, the contoured grip fits naturally in your hand to provide steady control and reduce hand fatigue during extended use. Its compact, lightweight body allows for smooth scanning across walls, ceilings, and even textured or uneven surfaces.
  • PERFECT FOR DIY AND PROFESSIONAL APPLICATIONS: Ideal for hanging artwork, TVs, shelves, cabinets, or mirrors, this stud finder delivers reliable results for both casual home projects and professional construction jobs. Requires one 9V battery (not included) to deliver powerful, consistent energy for precise, reliable scanning and long-lasting operation.
  • IMPORTANT: WireWarning Detection is a safety alert, not a wire locator. It warns of live, unshielded AC wiring nearby but does not identify exact wire position. For precise wire locating, choose a model with AC Scan Mode.

Good value stud sensor

It works well and is worth the money. It is a little finicky and indicates studs early - just need to stay in the center of where the unit marks the edges.
