You place it on the wall, and it goes hands-free when the stud is located. It also finds wood behind drywall, but it won’t work with plaster walls.
The magnet is a powerful neodymium variety, and because the StudBuddy is so small and thin, it slips into your pocket easily. The other great thing is you get 2 stud finders for the price, so individually, this stud finder is the cheapest to feature.
It is a limited device. You don’t get any LCD, no indicator lights, or beeping alarms to alert you. All you get is the pull of the magnet when it detects the stud.
Pros
- Simple to use, making it ideal for beginners.
- Compact and thin for easy storage.
- Hands-free operation when it finds the stud.

Zircon Multiscanner 740 Electronic Wall Scanner
Best Electronic Stud Finder
The differences between this Zircon multi-scanner and the CH Hanson are stark. This model has 4 scanning modes for AC wires, depth, wood, and metal. It has an auto-correcting feature to help improve user accuracy and a floating head that stays flat even when scanning over rough surfaces.
In StudScan and DeepScan mode, it detects the edges and the center of wooden joists and metal and wooden studs. In MetalScan, it finds non-ferrous metal like copper pipes and ferrous metal such as Rebar.
The AC Scan locates live and unshielded electrical AC wires. It also has a Wire Warning that operates when in StudScan mode when you find live AC wires. And when you discover your target, it has an erasable marker that pinpoints the exact location of the stud.
This model is the complete package, but all this technology costs. This one retails at over 3 times the price of the CH Hanson model. Many users also report that it locates wires, but when they make a second pass over the same spot, it shows no results.
Pros
- 4 scanning modes cover every possibility.
- Wire Warning feature that alerts when scanning live AC wires.
- Auto-correction feature to improve accuracy.
- Floating head for scanning rough surfaces.

How Do Stud Finders Work?
A stud finder is either an electronic or magnetic device that uses capacitance (a change in electrical charge) to detect metal studs and other supporting structures beneath the surface of your wall.
Because the stud is part of your wall support, the way the studs are inserted forms a logical pattern of a stud, then a gap, then a stud. The stud finder detects changes in the wall density to locate the studs and nails.
Stud finders have been around since the 80s, when the magnetic models first appeared on the market. Since then, they have come a long way. They are way more advanced and accurate today.
Types of Best Stud Finders
To decide which stud finder is right for you, we need to discuss the 3 main types of stud finders available. Each of the models does a specific task and suits every budget.
Magnetic
Magnetic stud finders are the original models, and they are still around today. The magnets have improved, along with their accuracy, but these models are less precise than their electronic and ultrasonic counterparts.
Magnetic devices are a lot easier to master and use. They react with the metal when the stud is located, sticking to the wall. If you are looking for a budget stud finder, a magnetic option could be a great choice.
Electronic
Electronic stud finders use electrical signals to find wall studs. The distinct advantage of an electronic stud finder is it is multi-talented. It can detect pipework and even live AC wires, making it incredibly useful to construction workers, homeowners, and electricians.
These modern devices are so accurate; they can even determine where the edge of the stud is rather than the middle.
Ultrasonic
Ultrasonic stud detectors use sound waves to locate studs beneath the surface. They are pricier and bulkier compared to the other two models, which makes them better suited to commercial settings.
How To Choose the Best Stud Finder
What are the important considerations to keep in mind when choosing a stud finder? Let’s find out.
What Is It For?
How you intend to use the stud finder matters because, for general DIY tasks, you could probably settle for an electronic or magnetic model. If you are using it commercially, you might get away with an electronic variety, but you might be better using an ultrasonic stud finder.
Type of Sensors
Stud finders come with sensors that differ in size and depth capabilities. This matters because if you are searching for nails and screws in a brick wall, you need something with the depth capability to work.
The wall depth, the material used to cover the wall, and the sensor’s abilities are all considerations when choosing your new device.
What About Accuracy?
Modern stud finders are more accurate than their magnetic counterparts. Some sensors are larger to cover more space. With a wider search area, you can accurately detect several studs in one hit.
While having more sensors spreads your range, they are less capable of dealing with deeper walls. Look for center-finding sensors that detect the stud with pinpoint accuracy, determining the edge of the stud.
What About the Budget?
The prices range massively. If all you want is a basic finder, you can spend as little as $15, while the more complex models with all the bells and whistles can cost $50 or more.
What About Self-Calibration?
Like all electronic devices, they need calibrating. Calibration is the way to ensure continued accuracy by resetting the sensors. Some do this automatically, which is super convenient. Others need manual calibration, which should happen regularly.
Tips for Using Stud Finders
As with all tools and devices, there are hints and tips to help you get the most from them. Here are some easy ways to use your stud finder.
Know Where To Start Looking
Sometimes some basic knowledge of where the studs are is the easiest way to use a stud finder. Door frames, window frames, even seams where the drywall meets the next sheet in the wall are all tell-tale signs of where the studs are likely to be.
Keep the Battery Charged
It all sounds so simple, but you’d be amazed how many times rechargeable batteries get forgotten about until it is too late. As the cell dies, you lose accuracy until, eventually, the stud finder is rendered unusable.
It’s also a great idea to keep a spare battery if your model allows for a detachable power pack.
Be Patient
Patience is always the best policy when locating studs. You might not find them straight away, even with the best quality stud finder. Don’t panic! You should start getting results within 15 minutes.
