Which stud finders are best?

It doesn’t matter whether you’re hanging a small mirror or a huge flat-screen TV, the best and safest way to do that is by securing the item to wall studs. The trouble homeowners often run into, however, is driving in a nail or screw and missing the stud completely. You’ll likely eventually achieve success, but possibly after making several holes in your once-pristine wall.

A stud finder helps you get it right on the first try. The best ones are accurate, can work on a variety of walls, and detect more than studs. The ProSensor Precision Stud Finder, for instance, features an impressive 13 sensors and is our top choice. To learn more about the ProSensor and other stud finders, keep reading.

What to know before you buy a stud finder

Types of stud finders

  • Magnetic stud finders are the most affordable of the two styles, and they use a strong magnet to find nails that are embedded in the studs. The homeowner slides the stud finder around the wall until he feels a tug, which alerts him that something metal is at that location. The downside is that the nails are not the actual studs, and they likely are not perfectly centered in the stud, so you still might have a miss or two. Also, the magnet will detect anything metal such as anchors, fasteners, pipes, conduit and wiring, not just nails, so you must be careful.
  • Electronic stud finders measure the density of your wall. Most need to be calibrated where you are certain there is no stud, then you slide the unit along, waiting for it to alert you that a stud has been found. Some models find just an edge, others use multiple sensors to indicate the center of the stud. All electronic stud finders require a battery to operate, and they can have inconsistent readings depending on the thickness and type of wall you are scanning.

What to look for in a quality stud finder

There are a number of other important features to keep in mind when choosing the best stud finder for your needs. A unit with AC wiring alert notifies you of the presence of live wires, which can be a literal life saver. Some sensors can detect the difference between wood and metal, which will come in handy if you have water pipes running through your wall. A stud finder’s interface is how the unit communicates what it finds. Some models beep, some flash a light, others have an LCD screen with more detailed information. Choose the type of interface that is the most intuitive to you.

How much you can expect to spend on a stud finder

A decent magnetic stud finder can be purchased for under $10. If you prefer an electronic model, however, you can get a basic edge-finding unit for $25-$35. At $50, you’ll find stud finders that can detect the center of a stud and likely have two operating modes and live AC detection. For a pro-quality tool, with advanced sensing features, you can spend up to $75.

Stud finder FAQ

Can I blindly trust a stud finder?

A. Unfortunately, no. You still must use caution and common sense. Many models can only inform you that something is behind the wall, they don’t identify what that something is. If it is a water pipe and not a stud, driving a nail could produce disastrous results.

What is the best strategy for using a stud finder?

A. The best way to use a stud finder is to perform multiple passes over a wider range of wall. You want to see consistent results and understand shapes and distances. If something doesn’t seem right, the unit could be “seeing” something other than a stud.
