Best Stud Finders (2026): 6 Picks for Drywall, Plaster and Tile
The best stud finder for most homes is the Franklin Sensors ProSensor M210. Its 13 sensors light up the whole width of the stud at once, so you see exactly where to drill instead of chasing a beep.
Older home with plaster walls? The answer changes, and a $15 magnet may beat a $100 sensor. Use the matcher below to find the right type for your walls.

The 3 Types of Stud Finder
- Multi sensor (Franklin): a row of sensors shows the stud’s full width with lights. No calibration, and you can start right on top of a stud.
- Edge finding (most others): one or two sensors beep at the stud edge. They need calibrating on a hollow spot first, and they struggle on uneven or thick walls.
- Magnetic: finds the nails and screws that hold the drywall or lath to the stud. No batteries, slower to use, but very reliable on plaster.
A fourth group, phone based wall scanners like the Walabot, show an image of what is inside the wall. They cost more and only work on drywall.

The 6 Best Stud Finders
1. Franklin Sensors ProSensor M210: Best Overall
The M210 changed how stud finders work. Instead of beeping at an edge, it lights up the whole stud across a row of 13 sensors, and it needs no calibration, so you can start anywhere on the wall.
- 13 sensors, deep scan up to 1.7 inches
- Finds wood and metal studs
- Live AC wire detection
- 4.6 stars from 6,600+ ratings
Worth knowing: Outdoor Life named it Best Overall, and Pro Tool Reviews labelled it the one that “actually works on plaster.”
Best for: Most homeowners, and the best single stud finder to own.

2. CH Hanson Magnetic Stud Finder: Best for Plaster and Lath
Plaster walls hide studs behind thick, uneven material that confuses many electronic sensors. A strong magnet finds the nails holding the lath, and those line up on the studs. It sticks to the wall when it finds one, so you can mark it hands free.
- Rare earth magnets, no batteries
- Finds nails and screws in studs
- 4.7 stars from 600+ ratings
Worth knowing: Outdoor Life named the CH Hanson its Best Magnetic Stud Finder. It is slower than a sensor because you sweep for each fastener.
Best for: Older homes, plaster walls and anyone who wants a cheap backup.

3. Franklin Sensors ProSensor MAX: Best for Thick Walls
The MAX uses larger sensors to read through two or more layers of drywall, plaster, OSB, plywood, MDF and large tile. If the M210 cannot see through your wall, this is the step up.
- 13 larger sensors
- Max detection depth 2.5 inches
- 4.5 stars from 600+ ratings
Worth knowing: It costs about twice as much as the M210, which is all most drywall needs.
Best for: Double drywall, sound proofed rooms, tile backsplashes and older thick walls.

4. Zircon MultiScanner A200: Best Edge Finder
Zircon invented the electronic stud finder, and the A200 finds wood and metal stud edges and centers, shows stud direction and warns of live AC wiring.
- Wood and metal studs, edges and centers
- Live AC wire warning
- 4.3 stars from 800+ ratings
Worth knowing: Like all edge finders it must be calibrated on a hollow spot, so start each scan away from a stud.
Best for: People who prefer a classic one button scanner with a display.

5. DEWALT Stud Finder: Best Budget
A simple center finding sensor with LED arrows and a marking channel. On standard 1/2 inch drywall it does the job for about $23.
- Detection depth of 3/4 inch for wood and metal
- AC live wire detection
- Auto calibration and audible alert
- 4.1 stars from 5,600+ ratings
Worth knowing: DEWALT says it will not detect through plaster, tile, concrete or foil faced materials.
Best for: Renters and anyone with standard drywall on a budget.

6. Walabot DIY 2: Best for Seeing Pipes and Wires
The Walabot plugs into a phone and shows an image of what is behind the drywall, including studs, plastic pipes and wires, up to about 4 inches deep. It is the tool to use before you cut a hole.
- Visual scan on your phone, iOS or Android
- Detects up to 4 inches into drywall
- 4.1 stars from 2,900 ratings
Worth knowing: The maker says not to use it on lath and plaster, concrete, tile, brick, stucco or metal backed walls.
Best for: Remodelers cutting openings in drywall.

How to Find a Stud Without Mistakes
- Start where studs usually are. In most US homes, studs sit 16 inches apart on center, sometimes 24. Outlets and switches are usually fixed to the side of a stud.
- Scan slowly and flat. Keep the tool flat against the wall and move it slowly. With edge finders, calibrate on a hollow spot first.
- Mark both edges. Then mark the center. A stud is only about 1.5 inches wide.
- Confirm before drilling big holes. Tap a finishing nail where you will drill, or check with a magnet. If it hits wood, you are on the stud.
- Check for wires and pipes. Stay away from the area directly above and below outlets and switches, where wiring often runs.
Mounting a TV? Use lag screws into at least two studs, and drive them with a drill or impact driver. Our impact driver vs drill guide explains which to use.
Frequently Asked Questions
What is the most accurate stud finder?
Multi sensor stud finders like the Franklin ProSensor M210 are the most consistent for most homes because they show the full width of the stud. On plaster walls, a magnetic finder is often the most reliable.
What is the best stud finder for plaster walls?
A magnetic stud finder such as the CH Hanson finds the lath nails that line up on studs. Pro Tool Reviews also found the Franklin M210 works on plaster.
Do stud finders detect live wires?
Many do, including the Franklin M210, Zircon A200 and DEWALT models. Treat the alert as a warning, not a guarantee, and turn off the circuit before cutting into a wall near outlets.
How far apart are studs?
Most US homes use 16 inches on center, and some use 24 inches. Measure from a found stud to predict the next one, then confirm with the tool.
Are magnetic stud finders better?
They are more reliable on plaster and cheaper, but slower, because you search for individual nails. Electronic multi sensor models are faster on drywall.
