A good stud finder can be the difference between a successful DIY home project and disaster. When hammering or screwing things into walls, ceilings, and floors, you need to know what is on the other side. Otherwise, you might damage drywall or flooring with unsupported items you are trying to install. That is why a stud finder is important.

All stud finders do the same basic thing: detect where support areas like studs and joists are along the wall. Some finders provide basic detection capabilities that are good for just walls. Others can be used on floors and ceilings. You should think about the project you have and the type of material you are working with since all finders are different in what they can detect. Some finders can detect wood, metal, plastic, or even live electrical wiring.

To cover all of your potential needs, here are the seven best stud finders.

    Best Overall Stud Finder: ProSensor 710 Franklin Sensors Precision

    Above anything else, a stud finder needs to be accurate. If you can’t trust the tool you are using to prevent utter disaster, there is no point in spending a dime on it. For a successful project, you need to know what you are dealing with on the other side of the wall. The ProSensor 710 Franklin Sensors Precision takes the top spot because of the accurate and detailed look it will give you while in use.

    The Precision can detect 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.

    Best Budget Stud Finder: Zircon StudSensor e50-FFP

    For the occasional weekend home project, a budget stud finder is a great option to save money. You still need to be careful, however, since many budget options lack the accuracy you need to reliably drill into your walls. Typically, the best budget options offer the basics without the extra detection capabilities. The Zircon StudSensor e50-FFP will give you basic wood and metal stud detection at an affordable price.

    This finder packs a lot of handy features within its small price tag. Capable of detecting both wood and metal studs, the finder will flash and beep once it has picked up the edge of a stud. It includes two scanning modes: StudScan for studs up to 0.75" deep and DeepScan for targets around 1.5" deep. The finder also includes the ability to detect live AC wires to avoid drilling into dangerous electrical hazards.

    Best Magnetic Stud Finder: CH Hanson 03040

    Magnetic stud finders are the old school cousins of modern, more advanced finders. Despite their simplicity, a good magnetic finder can be a great budget or additional option if you want something that will work without any batteries. Using a built-in magnet, stud finders like the CH Hanson 03040 will naturally be attracted to the nails and screws that hold the home’s frame together, giving you a good idea of where studs are behind the wall.

    The finder uses powerful rare earth magnets to find metal studs and fasteners without any need for power. The body of the finder also includes a two-way level so you can hang the finder from a metal stud for accurately leveling walls and other surfaces. A pointed arrow on the bottom will conveniently mark the safe spot for screws and nails, eliminating the need for trial-and-error while hanging pictures, frames and other objects onto the walls.

    Best Stud Finder for Plastics: DeWalt Wall Scanner

    Different materials in the floors, walls, or ceiling can present a unique challenge for stud finders. In many cases, the finder itself may only be able to detect wood studs. Plastic is especially challenging since a typical finder won’t register anything even when there is a plastic surface underneath. If you want to be sure you have something that will give you an accurate look at plastic surfaces, the DeWalt Wall Scanner is the best choice.

    The Wall Scanner is a heavy-duty finder that maps out the surface underneath the wall. Scans can ​pickup a variety of things such as wood, plastic, magnetic/nonmagnetic metals, and live wires up to three inches deep. The display will clearly display the location and type of interior structures like studs and wires and keeps an accurate map of the entire area so you can scroll back to see where you have previously scanned.​

    Best Stud Finder for Metals: Zircon MetalliScanner M40

    Metal is another support material that can be difficult to detect for typical stud finders calibrated for wood studs. Even magnetic finders might not register all types of metal since many metals aren’t magnetic. The Zircon MetalliScanner M40, on the other hand, is custom designed to detect a wide variety of metal supports and objects behind floors, walls and ceilings.

    The MetalliScanner will detect both ferrous (magnetic) and non-ferrous metals behind most types of nonmetal walls, floors and ceilings. Beyond metal studs and other support structures, this makes the finder great for locating smaller items like screws and nails deeply embedded into the wall up to four inches deep. The blue coil changes as you move the finder to reveal the precise location of any object it detects as well.

    Best Floor/Ceiling Joists Stud Finder: Bosch GMS120

    It’s important to have an accurate idea of the support behind the floors and ceilings if you have a project that requires drilling or hammering into these surfaces. Ceilings are particularly important since a nail or screw in the wrong place can bring a large chunk of drywall down onto your floor or even head. The Bosch GMS120 is a multi-scanning option that is comfortable to hold in awkward positions to reach the floor or ceiling.

    The ergonomic design of the finder houses a multi-mode sensor capable of detecting wood studs, metal support objects, and live AC wiring at the same time. This finder is the top choice for floors since it provides a deep 4.75" scan depth, and can handle materials as dense as cured concrete. The LCD display and audible detection signals also provide plenty of feedback for finding and noting objects underneath the floor surface.

    Best Live Wiring Stud Finder: Fetanten TS005

    One of the most dangerous, hidden things to avoid in the walls or ceiling is live electrical wiring. Wiring to the lights, outlets and switches can kill if you are drilling or hammering into your walls with the power on. Even when the power is off, you can still avoid the headache of severing a wire with a finder that can detect the smaller profile of wiring like the Fetanten TS005. If you want to play it safe with electrical wiring, this stud finder will give you an extra peace of mind while working.

    The finder includes four different scanning modes for woods, metals, AC wires and deeply embedded objects. Its AC detection mode is highly accurate with a range of less than +/- 1%. The basic graphical display features arrows that change location and shape to accurately mark the presence of detected objects as you move the finder around. With only three buttons on the front, the finder is extremely easy to use right out of the box.
