I recently had a project where I needed to install exhaust fans in two bathrooms which required new wiring, mounting the fan in the ceiling, putting in a wall switch, and venting the fans out of an exterior wall. I needed a stud finder for every one of those steps.

Having a reliable and accurate stud finder is also useful for simpler projects like mounting TV’s on the wall, installing shelving, hanging heavy art or pictures, mounting ceiling fans, and on and on.

Stud finders have been around for a long time, but modern units can do more than just find a stud. Some models detect magnetic and non-magnetic metals, wood and metal studs, and live wires. So now you can not only find your stud, but also get an idea of what else is running through your walls.

How I Tested the Best Stud Finders

To help you choose the best stud finder for you, I put ten of them to the test to see where they worked well, and where they fell short. I organized these tools into two basic categories: magnetic and electric. Magnetic stud finders are simply strong magnets in a housing that cling to the nails or screws beneath the paint and spackle on walls or ceilings. They’re great on drywall or painted OSB in a garage or shop, but they’re not effective on old construction that uses lath and plaster.

Electric stud finders send signals into your wall and interpret those signals when they bounce back. Some will find the edge of a stud, some will find both edges and indicate the center for you, and some will indicate pipes and electrical lines.

I tested the stud finders on a variety of mediums including new construction drywall, thicker ceiling drywall, paneling over drywall, OSB, MDF, and lath and plaster walls. The review for each stud finder will let you know where it excelled, and where it didn’t.

Best Stud Finders: Reviews & Recommendations

Best Overall: Franklin Sensors ProSensor M210

Pros

Accurate readings on studs and wires
Widest sensor area
13 sensors for high accuracy

Cons

Heaviest stud finder tested at 11.5 oz

Key Features

Shows whole stud: edges and center simultaneously
Live wire detection
Auto adjusts for material thickness up to 1.7 inches
Bubble level
Pencil included “on board” for marking
Price: $60

The ProSensor M210 was easy to use, gave almost no false readings, and it had the widest sensing area so you can “see” the stud coming.

This unit is held horizontally, unlike all the other sensors I reviewed, and it gave me the best view of what was behind the wall. As you move it horizontally across the wall, the stud would appear on the side and then move to the middle. In cases close to a door or window where there can be studs close together, I had more than one stud showing at once and I could mark them both. The M210 also showed live wires and the LED indicator would go from one to six lights as you got closer to the wire (6 lights indicate the center of the tool was right on top of it).

The M210 was very easy to use and did well on all mediums that I tested it on. Lath and plaster is the hardest medium to detect studs through, and while the M210 did struggle at times, it gave the most reliable readings out of the bunch.

The ProSensor M210 doesn’t have the most features, but I chose it as the best overall because it is simple to read and use. It’s the least picky about surfaces, and the multitude of sensors gave me the most consistent readings.

Best Featured Stud Finder: Bosch GMS120-27

Pros

Beep can be turned off
Easy to use and hold for long periods
Power button does not need to be constantly held like many other sensors
Highly sensitive

Cons

Poor performance on lath and plaster and 1-inch MDF board

Key Features

Screen indicates what is being detected, and the center of it
Live wire detection, metal pipe detection
AA batteries, or optional Li-ion battery pack
Color coded marking hole
Audible beep and lights for detection
Price: $99

The Bosch GMS120-27 was in strong contention for the best overall award because the feature set is awesome. It reads wood and metal studs, non-magnetic metal, magnetic metal, and wires. Plus, it gives audio and visual indication of everything.

The Bosch GMS120-27 also has a hole for marking the center. I found that it worked well for finding studs, pipes, and wires, even when they were next to each other. The center marking hole lights up green when you’re centered, which is really convenient. The screen displays symbols for what is behind the sensor, whether it be a stud, magnetic metal like a screw or nail, or non-magnetic metal such as a copper pipe, or a live wire. I found that I got good readings with the Bosch, but it did take some interpretation on my part when there were multiple objects close together.

Bosch didn’t take best overall was because it struggled with lath and plaster and it wouldn’t read through 1-inch MDF board (others units in the test did). Other than that, the Bosch GMS120-27 is a great tool that’s packed with capability, and it comes with a pouch to clip on your belt or pocket for easy access.

Best Magnetic Stud Finder: C.H. Hanson Magnetic Stud Finder

Pros

Bubble level rotates for vertical or horizontal orientation
Strongest magnets
Easy to slide across wall
Reliable way to find nails

Cons

More expensive than some electric stud finders

Key Features

2 magnets
Bubble level
Center mark
Loop for hanging plumb bob
Price: $15

The effectiveness of a magnetic stud finder really boils down to the strength of its magnets. In my testing the C.H. Hanson snapped to the screws and nails the fastest and seemed to have the strongest magnets of the three magnetic stud finders I tested.

You definitely know it when it runs over a nail or screw, which gives you confidence. As you make your passes back and forth across the wall, slowly moving up or down, you will eventually feel the magnet pull when you cross over a fastener. At that point, you just leave it on the wall, make your mark, and move onto the next stud. If you want to mark the whole thing, you can hang a light plumb bob off the bottom and mark the entire stud (assuming that stud is plumb).

Magnets lose their “power” quickly as you move away from the ferrous material, and so for lath and plaster magnets may not be reliable. However, magnetic stud finders are a simple and reliable way to find fasteners in studs, and the C.H. Hanson Magnetic Stud Finder had the best magnets (by a narrow margin) and that made it my pick for best magnetic stud finder.

Best Value: Zircon StudSensor A100

Pros

Lightweight
Accurate reading for studs
SpotLite Pointer for easy marking
Simple and easy to read screen

Cons

Beeping can’t be turned off
Wire detection only gets you close, not pinpoint

Key Features

Edge and center detection
Live wire detection
Deep Scan for up to 1.5 inches or Stud Scan for up to .75 inches
Visual and audible detection
Price: $33

The Zircon A100 finds the edge and center of a stud, has a stud or deep scan mode, and will detect wires, all for about $33. The Zircon A100 is simple to use and read, and gave me good readings for studs. The icon consistently lit when the sensor was near live wires. The “SpotLite” feature projects an arrow on the wall so you know exactly where to mark. The edges and center of studs are clearly indicated with a beep and lights.

The only downside is that the beep does not stop until you move off the stud, or let go of the power button. If you are marking the sides and the center, the beep can get a little annoying, but that is more of a nit-pick than anything. The Zircon A100 worked well, and was the only tool that offered wire detection at this price range, which is a nice feature for renovation and moving walls. Overall, the Zircon A100 best stud finder for the money.

Most Ergonomic Stud Finder: Klein Tools ESF150LL

Pros

Level and lasers make marking fast and easy
Comfortable grip and trigger set-up
Bright LED’s indicate edges and center of studs

Cons

No wire detection

Key Features

Shows whole stud, edges and center simultaneously
Lasers can project vertically and horizontally for marking
Bubble level
Trigger can be momentary hold or set for continuous scan
Scans up to 1.5 inches deep
Price: $60

The Klein ESF150LL has a unique design that has a pistol grip and trigger at an angle to the wall for comfortable use. The Klein Tools ESF150LL is the most comfortable stud finder to use. It has a pistol style grip with a trigger that can be held down for detecting, or, with 3 quick presses, it will stay in constant scanning mode. This is a great feature if you have to mark a bunch of studs.

The bubble level is easy to see and keeps the lasers plumb and level for marking. The button used to cycle through the lasers is easy to reach with your thumb while you’re holding down the trigger. You can have vertical only, horizontal only, or vertical and horizontal together. The lasers are bright and easy to see, and are convenient for laying out shelving or hanging things, and if you need to mark a whole stud from ceiling to floor, the Klein is the one to grab. The Klein gave more odd readings on lath and plaster than others in my test, but with a little patience, finding studs was still doable. The only real downside is the lack of wire detection.

Best Budget Stud Finder: Craftsman CMHT77633

Pros

Super lightweight
Easy on the wallet
Accurate on most surfaces

Cons

9v Battery costs almost as much as the tool
Need to detect from both sides to find edges, then measure for center

Key Features

Indicates edge of stud
Beep and Light to indicate
Lifetime warranty
Price: $12

The Craftsman is the least expensive stud finder in the test, and if you just need to find the edge of a stud, the Craftsman was plenty reliable. It’s the only tool with a lifetime warranty. The Craftsman CMHT77633 is an old-school electric stud finder. It will light up and beep when you come to the edge of a stud, and then you repeat the process from the other side to find the other edge. It won’t detect wires or pipes, but it’s only $12, and it has a lifetime warranty. For a basic unit, the Craftsman can’t be beaten. It did struggle with lath and plaster, but so did other much more expensive units. It’s rated for .75 inches of depth, but I was consistently detecting metal and wood behind a 1” MDF board. The Craftsman is cheap, basic, and pretty reliable. If that is what you need, the Craftsman is the tool for you.

Ryobi ESF5002

Pros

Accurate readings on wood and metal studs
Bright LEDs show edges
Center mark Button lights green to indicate center

Cons

No wire detection
Lots of false readings on lath and plaster

Key Features

Shows whole stud- edges and center simultaneously
Auto Depth Scan for wall material thickness up to 1.5 inches
Green LED indicator lights
Built in center mark punch
Price: $34

The Ryobi ESF5002 worked well on all surfaces except lath and plaster. The wide sensor shows the whole stud and the unique center punch lights up when you’re centered. The center punch is just a button with a sharp point that marks the wall when you push it. There is also a notch by the LED’s so you can mark the center with a pencil if you don’t want to leave a divot in the wall.

The Ryobi is light, but also one of the largest tools in the test. While it was reliable for finding studs, there were other tools that would do the same job for less money. I liked the center punch idea, and the LED’s are nice and bright. The batteries are easy to change and the tool works well. If you are a Ryobi fan, and want to keep with their line, the ESF5002 will get the job done, but I don’t think it has as much value as the other tools in its price range.

Stanley 77-050

Pros

Accurate readings on studs
Lightweight
Inexpensive

Cons

Less features than the Craftsman, but costs more

Key Features

Indicates edge of stud
LED to indicate
Scans up to .75 inches
Price: $15

The Stanley 77-050 looks identical to the Craftsman on the list, but it lacks an audible beep, and costs a few bucks more. It’s another old-school type stud finder that indicates the edge of a stud with a small LED labeled “edge”. However, unlike the Craftsman, the Stanley has the little sound ports blocked off and offers no beep. Other than that, (and the color) the Craftsman and the Stanley look and function identically. The Stanley is not a bad tool, but the Craftsman is superior. If it’s on sale, or the craftsman isn’t available, and you need an electric stud finder for cheap, then the Stanley 77-050 will do the job.

The StudBuddy Magnetic Stud Finder

Pros

No batteries required
Wide magnet spacing makes detection faster
Two Pack makes locating and marking studs easier

Cons

Magnets not quite as strong as others tested

Key Features

2 magnets in each
Made in USA
Price: $18 for 2-pack, $10 for single

The StudBuddy comes in a two pack, and the long narrow design makes lining up a stud easy work. The magnetic stud finders worked well, and it was really nice having two of them. I was able to leave one on the first stud I found, and then narrow my search for the next one by estimating the 16 inches between the studs. I was also able to leave one high on a stud and then search for the bottom of the stud which made marking a whole stud easy. The magnets were not quite as strong as the other two I tested, but the StudBuddy did slide easily across the wall surfaces and I was able to find all of the studs that the other magnet finders were able to. Overall, The Studbuddy was easy to use, and the differences between the magnetic stud finders were very small. The Studbuddy has the best price point, and they did a good job locating the fasteners.

Vaughan Magnetic Stud Finders

Pros

Easy to use
Durable
Level aids in accurate marking

Cons

Magnets not quite as powerful as the C.H. Hanson

Key Features

2 strong magnets
Bubble level has 4 positions
Plumb can be hung from either end
Price: $17

The Vaughan Magnetic Stud Finder did a good job sticking to nails and screws, and it slid easily across the different wall surfaces. It has a very similar build to the C.H. Hanson, and the only reason the Vaughan didn’t take the best spot is because the magnets were slightly weaker. However, it is basically a toss up between the magnet finders in the test (I did like the Vaughan bubble level). The Vaughan did a good job of finding nails and screws, and is a great low-tech way to get the job done.

FAQs

Q: How do I use a stud finder?

A: There are some small differences, but for electric stud finders, you place the finder against the wall, and then press and hold the power button until it calibrates, usually indicated with a beep or flash. Then you slowly move it across the wall and wait for it to indicate a stud. If there are strange readings, or flashing lights, repeat the process from a different part of the wall as you may have calibrated on a stud or other anomaly. For magnetic stud finders, hold them against the wall and move horizontally in a 2 ft wide zig-zag motion moving up or down the wall until the magnets find a fastener. I usually move about 2 to 3 inches up or down when I’m searching for a stud with magnets.

Q: Are there things that can affect my stud finders’ accuracy and readings?

A: Yes! Electric stud finders can be affected by very high humidity, or a high moisture content in a wall. For example, if you recently put in wallpaper, it will likely need to dry for more than a week before you can be confident in your readings. Many are so sensitive that having your other hand on the wall can affect the readings if it’s too close. Other electromagnetic fields from cell phones and other devices close by can also affect readings. Be sure to read the directions to eliminate these types of factors before deciding that the stud finder doesn’t work properly. Also, some wallpapers have metal foils or threads which can skew readings.

Q: Will my stud finder detect PVC or Pex pipes?

A: Generally speaking, no. But if they are full of water, they can sometimes affect readings on many detectors.

Q: Why is lath and plaster such a problem for stud finders?

A: Lath and plaster is difficult because it’s inconsistent by nature. Plaster is applied by hand, and so the thickness varies. Stud finders work by reading differences between materials, and having so much variability “confuses” the readings and makes it more difficult to get an accurate picture of where studs are.

Final Thoughts on the Best Stud Finders

Both magnetic and Electric stud finders have a place in the toolbox. The low-tech approach of the magnetic finders will work in many situations, and they are great for simple projects like hanging a TV or a shelf. However, for larger jobs that might include cutting new doorways, or new windows, or moving walls, a stud finder that will detect wires and pipes might save you a whole lot of headache and money. I’ll always have at least one of each in my tool kit because they each serve a purpose.
