Best Overall: Franklin Sensors ProSensor 710 Precision Stud Finder
Above anything else, a stud finder needs to be accurate. For a successful project, you need to know what you are dealing with on the other side of the wall. The electronic ProSensor 710 Franklin Sensors Precision takes the top spot because of the accurate and detailed look it will give you; its 13 sensors simultaneously "look" behind the walls or underneath the floors, pinpointing the location of wooden studs and metal objects easily and accurately.
Our product tester had high praise for this stud finder, saying, "The Franklin 710 locates studs quickly and accurately. You’re not left waving your hand over the wall for long before the 13 indicator lights start popping. This model is always in deep scan mode, so even if the walls are thicker than a standard .75 inches, you get an accurate reading."
The Precision can scan a wide area of wall while searching for studs underneath. The extra width of the device means you will have a more accurate sense of stud locations as you move the finder along the surface. LED lights on the front will light up, marking the location and width of any stud, so you will know exactly where the stud begins and ends as you work. This stud finder requires two AA batteries.
