In support of your research, we have compiled a list of the 10 best stud finders guaranteed to prevent disaster. All home needs are different, so some featured devices have advanced modes like AC wire detention and deep scanning.
What Is A Stud Finder?
A stud finder, as the name suggests, finds studs hidden in the framework of buildings. Different models detect metal, AC wiring, copper pipes, rebar, and studs. These scanners are either magnetic or electronic to achieve detection.
- Magnetic sensors. Only pinpoint metal hardware, nails, and screws attaching the covering material to the stud.
- Electronic sensors. Reveal the location of studs by displaying low dielectric constant readings on an LCD screen.
The Winning Item Of The Best Stud Finder
With the Franklin Sensor, finding studs is not hard, whether you are a novice or professional contractor. The model speeds up your stud search without hitching to calibrate readings.
You can rest assured of its accuracy too. It is always in deep scan mode to accurately scan surfaces thicker than the average drywall. And although the design is not ergonomic, it handles corners better than most classically shaped models.

The Complete List of 10 BEST Stud Finders for 2020
The Franklin ProSensor 710 is the most accurate and detailed scanner, making it our top choice. Unlike classic models, it uses 13 sensors for trustworthy readings so you can drill with confidence.
You will find the ProSensor 710 relatively convenient because it is capable of detecting multiple studs in broad areas. The length of the product means you can identify the center and edges of wood and metal studs simultaneously as you move along the surface. Then when the LED light flashes, mark the width of the location to know the exact space to work within. However, like most electronic options, it is expensive and provides optimal results.
- 90-degree edges fit in corners
- Detects multiple studs at once
- No Calibration Required
- Shows Stud Width
- Big and heavy
- No batteries included
- Precise location of stud edges not identified
If you want accuracy without buying batteries, consider the CH Hanson 03040. The magnetic finder has reliable, earth magnets built-in that are naturally attracted to the metals holding your frames together.
When you have found one nail or screw, confirm the presence of others to locate the stud underneath. It is strong enough to discover metal studs, ductwork, and electrical boxes.
Its strong magnet allows the finder to hang from the identified metal stud hands-free, allowing you to mark the safe drilling spot indicated by the pointed arrow before moving on. Ensuring you do not decorate your walls with holes when hanging photos and plants.
- Simple and effective
- No batteries necessary
- Limited to drywall screws and nails
Electrical wiring has the power to kill you if you hammer or drill into your wall or ceiling when current is flowing through. It is essential to detect where wires are and turn off the power before you start working. To remain safe, when you turn back on the lights use the Travool Sensor to check for wires.
This finder features 5 scanning modes for wood, metal, AC wiring, studs, and object embedded up to a depth of 60mm. The basic mode scans through one layer of drywall, but the deep scan mode observes through two layers. The easy to read LCD alerts users of wiring together with a sound warning system.

If you are looking for the best metal stud finder that is effective and accurate, it is hard to beat the performance of the Zircon MetalliScanner M40. This finder has two scanning positions, pinpoint and wide scan, to easily detect metals.
The detector locates magnetic metal under 4 inches of material, while non-magnetic metal detection has a depth range of 2 inches. When you move the device close to nails, screws, plumbing, or other metal hardware, the LED lights in the coil will change to indicate the precise location.
What sets the Ziron M40 apart is the ability to work with lath and plaster walls – making one of few metal objects under thick layers, including floors and ceilings. Another plus is that the easy to open packaging includes a battery. However, if you are a professional, it would better serve you to invest in the expensive and advanced Zircon MetalliScanner MT6.
- Scans through thick walls and concrete
- Find small metal targets like nails
- Locates both magnetic and non-magnetic objects
- Restricted to metal studs and hardware
- Requires fully charged batteries for the best results
Consistency is an issue that the typical stud finder struggles to maintain. Even when some sensors pick up the object the first time, the devices do not recognize the hardware if dragged over it again.
The DeWALT stud finder, on the other hand, consistently finds stud centers. This performance applies for both wood and metal studs located under half-inch and three-quarter-inch drywall.
One other advantage is the curved edges of the gadget that make detection possible at an angle. Additionally, the hand-held machine detects AC wiring reliably well through a half-inch drywall, plaster, and lath. Note that it may not pick up on AC wiring under three-quarter-inch drywall.
- One-hand operation
- Work well on dry and plaster walls
- Auto-calibration even at an angle
- Efficient center finding for convenience
- Wide detection area
This budget stud finder has scanning modes for wood, beam, joist, ferrous metals, AC wires, and objects deep underneath floors, walls, and ceilings. Not all metals are magnetic. The sensor applies to both ferrous and non-ferrous metals to overcome this issue.
Verified reviews often compliment the compact design and the great features offered affordably. Like the Franklin, the calibration is instant for time-saving convenience. This sensor shows green after calibrating. Yellow and red colors with buzzer sound alert users a stud center is near.
It does have its challenges. For instance, the design could use more padding for greater comfort. The good news is this model is the sweet balance between accuracy, inexpensive, and easy to use. Plus, the packing includes the first battery, and it has a 2-year warranty.
- Visual feedback provided by the LCD screen, green, yellow, and red indicator lights

What To Look For When Buying A Stud Finder?
- Sensor Type
Most commercial buildings have metal or plastic studs, while homes have wooden studs. Manufacturers often calibrate basic stud finders to find specific stud types within a certain thickness range. So, consider the material and location of the stud.
You may also want to take into account the need for batteries and price. Electronic field sensors are usually more expensive and need batteries, but magnetic sensors are more affordable and do not require external power.
- Grip Design
Remember, you need to move the stud finder along a solid surface. So, smooth, uninterrupted motion is ideal to avoid false readings. Simple designs with an ergonomic structure like rubber grip padding are the most comfortable to hold.
- Center Targeting Function
Since the center of the stud is better for fastening, some advanced electronic sensors include this helpful feature to help you find it. With a basic model, you will have to guess based on the location of nails and stud edges.
- Additional Features
Additional features are pretty expensive and common among electric stud sensors. Besides live wire detection, there can be an audible warning noise and light displays above the scanner to mark the exact spot for drilling.
Why Do You Need A Stud Finder?
Well, because without x-ray vision, you need a device to find the load-bearing structural support of your building. Otherwise, you could pierce pipes or wiring or have heavy objects suddenly collapse.
How to Use a Stud Finder?
Here is the general procedure. Be sure to read your manual, though, as manufacturer procedures vary.
- Turn on
Insert batteries into the device. Power on and choose the desired scanning mode.
Lay the device flat against the wall. Keep your hand steady, then press and hold the button for 1-2 seconds. Or until you hear a short beep sound and the loading bar on the LCD screen clears to indicate calibration is complete.
- Check the Surrounding Area
Before you declare success at finding the right spot, hold the button. And slowly drag the stud finder along the area for a thorough scan.
- Conduct Your Renovation
Beeps and LCD screens, if available, signal the detection of an object. When you have located a safe area, begin your home upgrade project.

Frequently Asked Questions
- Can I find studs behind a tiled wall?
Yes, but getting precise readings are difficult. We recommend using an advanced scanner with multiple modes.
Kitchen and bathroom tiled walls typically have a lot going on underneath, such as gas pipes, water lines, and live wires. A regular scanner with only a stud scan or deep scanning mode will not accurately assess everything beneath the tiled surface.
- I believe there are electrical wires. Why does the stud scanner not identified any?
Despite advances in technology, it is still hard to locate live wiring.
Electric field scanners will not reveal anything if the wires are in concrete, behind a plywood shear wall or metal panel, more than 2 inches from the surface, encased in conduit, or if moisture is present.
We recommend using the metal scan mode or a magnetic sensor to discover metal conduits, metal, or wires. Before penetrating the surface, always turn off the electricity, water, and gas as an extra precaution.
- Why does the stud finder blink or beep when I press the power button?
This blinking or beeping occurs when the battery charge is low. Scanning requires robust power, especially in models with backlit LCD screens. Replace dying batteries with a new battery fitting the manufacturer’s requirements.
- How do I change the batteries?
Battery changing for most electronic devices do not require unscrewing. Like you would your remote, unlatch the raise section of the finder following the direction of the indentation.
- What is the difference between wire warning and AC scanning?
In addition to the scanning for studs and metals, the wire warning feature alerts you to the presence of live, unshielded, electrical AC wires. But AC scanning narrows the general location of live wires.
We hope this list of the best stud finders was helpful.
Since no two walls, floors, or ceilings are alike. Each recommendation is perfect for different situations to ensure safety when puncturing your surfaces.
Our overall best pick is the Franklin Sensor ProSensor 710 Stud Finder. This device is excellent because of its accuracy.
