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.

Works good
Good stud finder for the money. It’s easy to use and does a good job at locating studs in the wall. The size is not bad as it fits comfortably in my hand with no problems. The accuracy for the most part is good but like almost every one of these I’ve used, it’ll always have its moments where it doesn’t seem to do right. But it ends up working out fine and gets the job done.

Wall Scanner and Center/Edge Locating Stud Finder
Great stud finder that also will show you where there are electrical wires. Used this to place another electrical outlet up higher on the wall for my wall mounted TV. Was very accurate in finding the stud and let me know there was a live wire right next to the stud so that I didn’t cut into the wire when cutting the hole in the sheetrock. Easy to use, screen is easy to read, works well. Great buy!

Make sure you use new batteries
I thought this product would be easy to use, but I continually kept getting error messages and beeping. It does not seem very reliable or accurateUpdate: After reading online, it seems that the malfunctioning may have been caused by the fact that the battery I was using was a few years old (although unused). I replaced with a newly purchased battery, and it seems to be working fine now. I like that the light arrow shows you where the edge of the stud is

Issues consistently finding the studs
I have used this brand in the past since its always available and affordable in store but this one had difficulty finding the studs. It would say there is a stud there at one point then we would pass over the same spot and it would not light up so i’m not sure how accurate it is. It is very light so it does not make your work bag any heavier but If there is a better quality version out there i would spend more money on it.

I’ve bought a few stud finders under a $100 including renowned brands but none actually came even remotely close to this thing. It does the job and it does it well, 100% recommended!

Debes tener en cuenta que el producto es compatible con paredes de yeso, tabla roca y madera, no funciona con ningún otro tipo de paredes ya que da falsos positivos.Tiene una calificación decente ya que en EU usualmente las casas son de esos materiales y en ese contexto si cumple su propósito.La versión que adquirí fue la A100, ni esa ni las demás A150, A200 y A250 funcionan con otro tipo de paredes.Compra el producto pensando en esto.
