The best renovations are event-free. That is why a good stud finder is crucial. Because if you are guessing what is on the other side of your floors, ceiling, or wall, accidents are very likely.
A stud finder ensures you or your contractor finds the safest spot to drill or hammer for zero headaches and simple home upgrades. So, that big, flat-screen television stays mounted.
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.
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.
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 stud’s center 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.
The Winning Item Of The Best Stud Finder of 2022
With the Franklin Sensor, finding studs is not hard, whether you are a novice or a 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.

- 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, they 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.

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.
