Top 10 Stud Finders of 2025: Expert Reviews & Buying Guide

Stud finders are great for when you need to hang something in your home, like mounting TVs, shelving, or mirrors. Whether you’re looking for wiring, pipes, or just the usual stud, these models are designed to help you locate it. Studs are wooden or metal supports that provide the strength needed to hold heavier items like shelves, TVs, or artwork. A stud finder saves you a ton of time (and potential wall damage) by ensuring you drill right into the sturdy support every time.

Types of Stud Finders

Magnetic Stud Finders

Magnetic stud finders catch on the fasteners that attach drywall to studs as you wave a magnet along the wall. Since fasteners often sit over a foot apart on a single stud, locating one with a magnetic stud finder may take longer, but this option is affordable and quite simple to use. They sense nails instead of studs, so keep in mind that the mark you make on the wall shows the presence of a nail and not the edge of a stud. Accuracy is not a magnetic stud finder’s best attribute, however. Because these tools rely on the fastener actually being driven into the stud, if a builder missed the stud, so will the magnetic stud finder.

Electronic Stud Finders

Their counterpart, the electronic stud finder, sends out a signal from a sensor and then reads the signal that bounces back. When the signal changes, the stud finder beeps or flashes to let you know it’s found a stud. Electronic stud finders detect density changes in the wall and can find studs under most wall surface types. They are more accurate and can help you avoid costly mistakes on your wall. For most drywall projects, a 1.5-inch scanning depth is all you need.

Radar-Based Stud Finders

The most advanced stud finders use technology like ground-penetrating radar, which creates a subsurface image. Radar-based models, like the Walabot DIY 2, offer unprecedented accuracy and even the ability to “see” through your walls. This revolution in stud finding means you can locate pipes, wires, and more alongside traditional studs.

Top 10 Stud Finders of 2025

1. Bosch GMS120 Digital Multi-Scanner

The Bosch GMS120 is a powerhouse of a wall scanner. It has three modes; wood, metal, and electrical power, and is quite accurate with all three. In addition to the three scan modes, the Bosch has a center finder for studs, a magnetic sensor to show screws and other metal, and a ring that changes color depending on how close you are to the material you’re seeking. On the downside, we wish the stud finder was a little smaller; as it is, it’s rather bulky and takes up most of the pocket on a tool belt. Its accuracy is admirable, but it takes three passes of an object to detect its location accurately. Buy on Amazon

2. Franklin Sensors ProSensor M210

Featuring 13 sensors with 21 LEDs over a 7-inch width, this model is more precise in both the sensor and the display than other options. Using AA batteries for power, it’s capable of detecting the full width of wood or metal studs up to 1.7 inches deep, which is handy if you’re working on walls with more than the standard single sheet of drywall covering it. There’s an AC detector to let you know if there are live wires nearby and a built-in level to help you lay your markings straight. There’s even a pencil caddy to keep a pencil on board so you have one when you need it. Buy on Amazon

3. Zircon MultiScanner A200

This electronic option comes with center and edge detection, and it works on live wires as well as wood and metal studs. Plus, it has a large, easy-to-read LCD screen. The A200 has modes to detect wood, metal, and live wires, as well as a deep scan mode for penetrating thick walls. While it doesn’t have as many specialty modes, it is still quite accurate and easy to use. Buy on Amazon

4. Franklin Sensors ProSensor M90

Out of all stud finders we tested, this was the most accurate. It gives precise readings thanks to its nine sensors, which find studs instantly as you move it along the wall. Unlike other stud finders that need to be calibrated before each use, you don’t have to do that with this unit, saving you time and making it more convenient. The sensors light up when it detects the entire length of the stud, not just the edge, so you can determine precisely where the edges or center are. Those with smaller hands may not find it as comfortable to hold. Buy on Amazon

5. C.H. Hanson 03040 Magnetic Stud Finder

Equipped with two magnets, this C.H. Hanson model is a basic, durable tool that scans twice as fast as the rest. It’s fast. Because the C.H. Hanson model has two magnets instead of just one, it scans twice as fast as the other magnet-based finders we tried. When you swipe it across a wall, it covers approximately a 2.5-inch swath. It simplifies the act of marking a stud. In the center of the tool is a small level vial that you can rotate; it clicks securely into place at the horizontal and vertical orientations. Buy on Amazon

6. Craftsman 3/4-Inch Depth Stud Finder

From the trusted Craftsman brand, this no-frills stud finder offers basic stud detection at an affordable price. Easy to read and use, the Craftsman is overly large but finds studs well. It has a depth range of ? inch, which will work through any fabric or wallpaper. Buy on Amazon

7. Zircon MetalliScanner M40

The Zircon MT6 is a specialist stud finder that detects metal items inside walls. With a detecting depth of up to 152mm, it is suitable for finding pipelines and rebar. Its huge LCD display produces clear and exact results, making it a crucial tool for the construction industry. This model is highly accurate when detecting metal studs or nails and screws within wood studs. Buy on Amazon

8. Walabot DIY 2

Our top pick is the Walabot DIY 2, the first visual stud finder that works with your smartphone. Radar-based models, like the Walabot DIY 2, offer unprecedented accuracy and even the ability to “see” through your walls. This revolution in stud finding means you can locate pipes, wires, and more alongside traditional studs. Buy on Amazon

9. StudPop Original Magnetic Stud Finder

The WoLF Magnetic Stud Finder SFN45 is a compact and efficient instrument for swiftly locating studs in walls, ceilings, and floors. Its powerful magnet can identify metal fasteners, screws, and nails, making it suitable for both experts and DIY enthusiasts. This stud finder does not require batteries, so it is always ready to use whenever you need it. Buy on Amazon

10. Calculated Industries StudMark Magnetic Stud Finder

This device uses powerful magnets to effortlessly locate studs behind drywall, eliminating the need for batteries and the risk of wall damage. It’s about the size of a marker pen and doesn’t require batteries. Buy on Amazon

Testing Scenarios and Performance

Faux Wall Drywall Test

To ensure the stud finders were sensing what they said they were, we framed up a faux wall complete with finished drywall. Inside, we had studs of course, but we included some other common wall interior finds, such as a wire, a PVC pipe, a copper pipe, and a galvanized pipe. We used each stud finder to scan the wall and recorded how accurate it was when identifying the edges and center of the studs. The Franklin Sensors ProSensor M90 accurately found the edge, center, and length of studs across all three wall types, plus it detected metal as well as PVC and copper pipes. The Bosch GMS120 consistently found the stud on drywall but struggled with deep scanning on thicker materials.

Real-World Home Projects

We used these products to install over 50 picture frames at home and hang bike racks in the garage to test consistency and evaluate the reliability of each. The Zircon A150 consistently did well in most tests. This consistent performance is the main reason we liked it. On our wood-paneled wall test, the A150 was one of the few that was able to sense a stud fairly consistently. On the stucco test, it couldn’t find a stud, but neither could almost any of the other models tested.
