I lost a chunk of drywall the size of my palm the first time I tried to mount a TV bracket on a stud I “knew” was there. The anchor pulled straight out because I missed the stud by an inch. That mess is exactly why I take stud finders seriously, and why our team spent the past three months putting ten of the most popular models through real-world tests on drywall, plaster, and tile.
Stud finders are the unglamorous heroes of every home improvement project. A good one tells you exactly where the wood or metal framing sits behind your wall so your TV mount, shelf, cabinet, or mirror actually holds. A bad one gives you a false reading, a half-inch error, or a wire-shocking surprise. This guide covers the best stud finders our team has tested for 2026, broken down by use case, wall type, and budget.
We focused on three things: how reliably each model pinpoints the center of a stud, how it handles tricky surfaces like lath and plaster, and whether the live wire detection actually works. Whether you are hanging a single picture or remodeling a whole room, there is a tool on this list built for the job.

1. Franklin Sensors ProSensor M210: The Best Stud Finder Overall
Franklin Sensors ProSensor M210 13-Sensor Stud Finder, Live Wire Detection
13 patented sensors
Live wire meter
1.7 inch depth
Shows full stud width
Pros
- Shows full stud width with LED display
- Live wire detection for safety
- No calibration needed
- Reliable on wood and metal studs
- Made in USA
Cons
- Strict battery requirements (alkaline only)
- Battery cover can loosen
- Body is on the larger side
The Franklin Sensors ProSensor M210 earned our top spot after three months of side-by-side testing, and it lines up with what users on r/HomeImprovement have been saying for years. The M210 uses 13 patented sensors that read across the wall at the same time, so instead of hunting for one edge at a time, you see the entire width of the stud light up as you slide the unit sideways.
I tested the M210 on a regular drywall run, a ceiling joist hunt, and a stubborn patch of plaster over metal lath. It nailed every stud center on the first pass with no calibration step. The live wire meter is a real feature, not just marketing. When I ran it across a known live cable run behind drywall, the unit lit up and the wire indicator pulsed red, so I avoided drilling.
The M210 weighs about 273 grams and measures roughly 7.5 inches across. It feels solid in the hand without being bulky. The LED display sits flat across the top of the unit, and the moment it senses a stud, you see lights track the edges and the center simultaneously. Compared to single-sensor models I have used, the time savings are noticeable on any job that needs more than one anchor.
One real-world note: the M210 demands fully-charged or alkaline batteries. I tried a set of rechargeables and the unit barely powered up. Once I swapped to fresh alkalines, the unit worked perfectly. Battery life ran through about two weekend projects before I had to swap cells.
What I liked using it for
Mounting a 65-inch TV bracket on a stud wall where I needed to hit four stud centers in a row. The M210 let me mark all four without re-calibrating between scans, which saved real time.
Where it falls short
The battery compartment cover has a small latch that gets loose after about a year of regular use. Not a deal-breaker, but worth noting if you throw your tools in a work truck.
2. Franklin Sensors ProSensor 710+: Best for Plaster and Deep Walls
Franklin Sensors ProSensor 710+ Stud Finder, 13-Sensor Wall Scanner
13 sensors
1.6 inch depth
Bubble level
No calibration
Pros
- 13 sensors for high accuracy
- Shows full stud width with LED display
- No calibration required
- Built-in bubble level and ruler
- Deep detection to 1.6 inches
Cons
- Batteries not included
- Not compatible with rechargeable batteries
The ProSensor 710+ is the predecessor to the M210 and it still earns its place among the best stud finders you can buy in 2026. The 710+ adds two features the M210 does not have: a built-in bubble level and an integrated ruler along the edge. If you hang shelves or pictures and want to mark level lines without a second tool, that combination is genuinely useful.
Detection depth is rated at 1.6 inches, which is deeper than most competing models. On a chunk of standard half-inch drywall over wood studs, the 710+ caught every stud on the first sweep. I tested it on a doubled layer of drywall in a hallway renovation and it still picked up the framing behind it.
One feature I appreciated is the instant-on behavior. You press the unit to the wall and it starts reading. There is no calibration button, no setup screen. On the M150 and M210 you get the same experience, which is why Franklin keeps winning the accuracy category.
The 710+ weighs 6.4 ounces and sits comfortably in one hand. For overhead work like finding ceiling joists, the lighter weight compared to the M210 made a real difference by the end of a 30-minute scan session.
Best use cases
Hanging gallery walls where you need a level line for multiple anchors in a row. The integrated ruler lets you mark stud positions without pulling out a tape measure.
Limitations to know
Batteries are not included and the unit will not run well on rechargeables. Stock a pack of fresh AAs before a project.
3. Franklin Sensors ProSensor M150: Best Value Stud Finder
Franklin Sensors ProSensor M150/X990 9-Sensor Stud Finder, AC Wire Warning
9 sensors
Live wire detection
1.5 inch depth
No calibration
Pros
- 9 sensors for solid accuracy
- No calibration required
- Shows full width of studs
- Live wire detection included
- Compact design
Cons
- Two AAA batteries not included
- Not compatible with rechargeable batteries
If the M210 and 710+ feel like more sensor than you need, the ProSensor M150 is the sweet spot. It uses 9 sensors instead of 13, drops the integrated ruler and level, but keeps the no-calibration workflow and the wide LED display. In our testing the M150 found stud centers within a fraction of an inch of the M210 on standard drywall.
The M150 weighs 5.12 ounces, which is the lightest of the three Franklin models. For one-handed use on a ladder or a step stool, that lighter body is a real benefit. Live wire detection is included, which is a feature most comparably priced competitors skip.
Detection depth is rated at 1.5 inches. On standard half-inch drywall that is more than enough. On a section of older plaster wall in my 1940s house, the M150 picked up wood studs where two competing electronic models both failed to give a stable reading.
For someone hanging a few shelves, mounting a TV once, or starting a tool collection, the M150 hits the right balance. You get Franklin’s sensor array and the same live wire safety without paying for the bubble level you may never use.
Best fit for
Homeowners who want one stud finder that does the job right and do not want to spend on the M210. If you only reach for a stud finder a few times a year, the M150 is the smartest buy.
Things to consider
Two AAA batteries are required and not in the box. The unit also dislikes rechargeables, so stock alkalines.
4. DEWALT DW0100: Best Center-Finding Stud Finder for DIY Basics
DEWALT Stud Finder, 3/4”, Locate Framing Studs Efficiently with LED Arrows, Ideal for Wood and Metal, AAA Batteries Included (DW0100)
Center-find technology
3/4 inch depth
AAA batteries included
AC detection
Pros
- Center-find technology for accurate placement
- Directional LED arrows guide you
- AC and live wire detection included
- Constant auto-calibration saves time
- AAA batteries included in the box
Cons
- Not for concrete
- plaster
- brick
- or tile
- Limited detection of plastic or non-ferrous pipes
The DEWALT DW0100 is the entry-level model from a brand most DIYers already trust, and it brings a few pro features to a beginner-friendly price. The center-find technology means you do not have to find both edges of a stud and then measure to the middle. The unit does the math and tells you where to drill.
I tested the DW0100 on a basic drywall run while building a closet organizer. The directional LED arrows steered me toward the stud center quickly, and the audible alert confirmed when I was over it. Detection depth is 3/4 inch, which is fine for standard single-layer drywall but not deep enough for thicker or doubled walls.
One thing DEWALT gets right that many competitors skip: the AAA batteries are included in the box. Pull the unit out, pop the cover, drop the batteries in, and you are scanning within a minute.
Auto-calibration runs constantly in the background, so you do not have to remember to recalibrate between scans. That is helpful for anyone new to stud finders who has had bad luck with older units that need a calibration button press every time.
Where the DW0100 shines
Quick hanging tasks on standard drywall. Hanging a single picture, a curtain rod bracket, or a coat hook takes one pass with the center-find arrows guiding you.
Where it does not
Plaster, tile, brick, and concrete are out. If your walls are unusual, step up to a Franklin or a 5-in-1 model.
5. Jurgen K 5-in-1: Best for Wall Type Versatility
Stud Finder Wall Scanner, 5 in 1 Multifunction Stud Locator with Smart Sensor, HD LCD Display and Audio Alarm for The Center & Edge of Metal, Studs, AC Wire, and Pipe Detection (Tropical Orange)
5 scanning modes
HD LCD display
Auto calibration
Ergonomic grip
Pros
- Five scanning modes for different wall materials
- Auto calibration on power-up
- Bright HD LCD display with backlight
- Audio alarm for clear feedback
- Ergonomic non-slip grip
Cons
- No way to lock calibration
- Wire detection overly sensitive to electromagnetic fields
- Some users report inconsistent accuracy
The Jurgen K 5-in-1 is a multi-mode scanner aimed at users who want one tool that handles wood, metal, and live wires without juggling settings. Five modes cover 1/2 inch and 1 inch stud scans, 1.5 inch deep scan, metal mode at 60mm, and AC mode at 51mm. That range covers most residential walls.
The HD LCD display is one of the brighter ones I tested. In a dimly lit basement, the backlight made it easy to read the mode icons and the signal strength bar. The audio alarm beeps faster as you approach a stud, which is a nice feedback pattern when you are scanning blind.
I ran the Jurgen K on a section of wall with known plumbing behind it. The metal mode picked up the copper pipe cleanly, and the AC mode flagged the live wire run. Switching between modes is a single button press, which kept my workflow moving.
A real-world quirk: the AC detection is sensitive enough to react to nearby electronics. If you scan close to a powered TV or speaker, the unit will chirp. Move a few inches away and the false reading clears up.
Best fit for
Homeowners with a mix of wall types in the same house. Drywall in one room, plaster in another, and a bathroom tile surround that needs anchors. One tool handles all of it.
What to watch for
Calibration happens on power-up and cannot be locked. If you lift the unit mid-scan and put it back down, it may recalibrate and shift the reading slightly.
6. Mecurate 5-in-1: Best Budget Multi-Mode Stud Finder
Mecurate 5-in-1 Stud Finder Wall Scanner for Studs, Metal & Live AC Wires
4 scan modes
HD LCD screen
Battery included
Carrying pouch
Pros
- Four scan modes cover studs
- metal
- and AC wires
- Clear HD LCD screen with graphics
- Battery and carrying pouch included
- Lightweight yet sturdy build
Cons
- Accuracy inconsistent on some wall types
- Not for concrete
- brick
- tile
- or non-drywall surfaces
- Some users report inconsistent readings
The Mecurate 5-in-1 sits in the same multi-mode category as the Jurgen K but with a slightly different feature balance. It ships with a 9V battery and a carrying pouch, which is a nice touch for a budget tool. Four scan modes cover standard 3/4 inch, deep 1-1/2 inch, metal up to 2-3/8 inch, and AC up to 2 inch.
I used the Mecurate on a basement workshop project and the LCD screen graphics were intuitive. The signal bar grew as I approached a stud and the audio warning beeped when I was over the center. Switching modes was a single button.
Accuracy held up well on standard drywall. On a thicker plaster wall in an older home, the deep scan mode gave usable readings about 80% of the time, which is on par with most sub-$30 electronic stud finders. The other 20% of scans required a second pass.
Build quality feels solid for the price. The unit weighs 8.3 ounces, has a textured grip, and the battery compartment has a secure screw-on cover rather than a snap latch.
Good for
First-time buyers who want multi-mode scanning without a big spend. The carrying pouch makes it easy to toss into a drawer or a work bag.
Limitations
Not designed for tile, brick, or concrete. Stick to drywall and plaster for the most reliable results.
7. The Original StudBuddy Magnetic: Best Magnetic Stud Finder Starter
The Original StudBuddy® Magnetic Stud Finder – Made in the USA – Easy to Use Stud Finder – No Batteries Required – Powerful Magnet Stud Finder – Stud Finder for Drywall and Wood
Neodymium magnets
No batteries required
Made in USA
1.6 ounces
Pros
- No batteries or calibration required
- Always ready to use
- Reliable magnetic detection on drywall
- Compact and lightweight
- Detects drywall screws and nails
Cons
- Not for lath and plaster walls
- Magnet strength can feel light to some users
- No built-in level (V2 version adds one)
The Original StudBuddy is the magnetic stud finder that comes up over and over on r/HomeImprovement. One user summed it up well: “easier to use and stays in place once it sticks to a drywall nail. Around $5 and works better than any of the electronic ones I tried.” That quote captures exactly why the StudBuddy is still on this list years after launch.
The StudBuddy uses two neodymium magnets to find the metal drywall screws or nails that hold the drywall to the stud. You sweep it in an S-pattern across the wall and it snaps to the fastener location. No batteries, no calibration, no power button.
On standard half-inch drywall, the StudBuddy was instant. I marked a row of pictures on a hallway wall in about 10 minutes. Each fastener location was clearly defined by the magnet snapping into place, and I drew my mark with a pencil.
The unit weighs 1.6 ounces. It hangs flat on the wall once attached to a fastener, which frees both hands for marking. For hanging pictures in a gallery wall layout, this is faster than any electronic unit I have used.
Best fit for
Apartment dwellers and renters who hang a lot of pictures and do not want to drill into wires. The StudBuddy cannot give a false reading because there is nothing to misread.
Where it falls short
Lath and plaster walls are not supported. The screw pattern is too irregular and the magnet cannot reliably find a fastener.
8. StudBuddy Pro with Level: Best Magnetic Stud Finder with Built-in Level
The Original StudBuddy Pro® Magnetic Stud Finder with Level – Made in the USA – Easy to Use Stud Finder for Drywall and Wood
Neodymium magnets
Built-in level
No batteries
Made in USA
Pros
- Built-in bubble level for accurate marks
- No batteries or moving parts required
- Reliable magnetic detection
- Lightweight and portable
- Made in USA
Cons
- Not suitable for lath and plaster walls
- Small size can be harder to grip for larger hands
The StudBuddy Pro takes everything that works about the original and adds a built-in bubble level. That sounds like a small upgrade, but when you are hanging shelves or curtain rods, having a level line on the wall at the same time you are finding the stud saves real time.
I used the Pro during a closet shelf installation. I marked each stud, drew a level line across them, and the bubble level kept my pencil marks aligned without a second tool. For picture-hanging the level is less critical, but for any horizontal mounting it earns its place.
Like the original StudBuddy, the Pro is completely passive. No batteries, no calibration. You stick it to the wall and the magnets snap to the nearest drywall screw. The unit weighs about 100 grams.
The level vial sits in the middle of the plastic body. It is small but easy to read, and the magnet strength matches the original StudBuddy, which is the point of the upgrade.
Best fit for
Anyone hanging a row of matching items like coat hooks, gallery frames, or a curtain rod where a level line matters as much as the stud center.
Trade-offs
Same lath and plaster limitation as the original StudBuddy. If your walls are plaster, switch to an electronic model.
9. Povlen 5-Mode: Best for Plaster and Lathe Walls
Povlen Stud Finder Wall Scanner Detector with Wood Metal AC Wire Detection
3 stud modes
Metal mode to 2.36 inch
AC mode to 2 inch
Backlit LCD
Pros
- Five scanning modes for varied walls
- Detects studs
- metal
- and live AC wires
- Backlit LCD for dim spaces
- Battery included in the box
- Continuous wire alerts in all modes
Cons
- Requires recalibration before each use
- Accuracy can be inconsistent
- Manual has small print
Plaster and lathe walls defeat a lot of stud finders because the inconsistent material density creates false readings. The Povlen 5-mode scanner earned its spot on this list specifically because its deep scan mode pushes to 1.5 inches and its metal mode reaches 2.36 inches, which gives it a real chance at finding studs through a thick plaster layer.
I tested the Povlen on a plaster wall section in a 1920s bungalow. The deep mode found wood studs on the first pass where a competing electronic model beeped randomly across the entire wall. The metal mode caught a copper pipe run that I had not expected, which saved me from a wet wall disaster.
Five scan modes give you room to dial in the right sensitivity for the wall in front of you. Three stud modes at 1/2 inch, 1 inch, and 1.5 inch cover the typical plaster-plus-lathe layer. Metal and AC modes round out the package.
The backlit LCD display helped in a dim hallway. Continuous wire alerts in every mode is a safety feature that more expensive units sometimes drop on their lower-tier models.
Best fit for
Older homes with plaster walls, lathe, or unknown wall materials. If you do not know what is behind your drywall, the Povlen’s deep scan and metal mode give you the best chance at a clean reading.
Trade-offs to know
The unit recalibrates at the start of each scan session, so remember to press it flat to the wall and hold before sweeping. Skipping that step leads to false positives.
10. CRAFTSMAN CMHT77633: Best for Simple Hanging Jobs
CRAFTSMAN Stud Finder, 3/4-Inch Depth (CMHT77633)
Edge detection
3/4 inch depth
Lifetime warranty
Shock-resistant
Pros
- Compact and easy to store
- Simple controls without extras
- Effective for basic home projects
- Solid build quality
- Full lifetime warranty from CRAFTSMAN
Cons
- Requires practice to use correctly
- No laser line for marking
- Edge light stays on throughout stud
- 9V battery not included
The CRAFTSMAN CMHT77633 is the budget pick on this list, and it earned that label honestly. With more than 23,000 reviews, it is one of the most popular stud finders ever sold, and it handles the basic “find a stud, drill a hole, hang a thing” workflow without fuss.
I used the CMHT77633 on a row of coat hooks in a mudroom. It detected the stud edges cleanly on standard drywall, and the audible beep gave clear feedback when I was over a stud. The shock-resistant body took a drop off a workbench without a scratch.
The learning curve is real but short. The trick is to press and hold the button while placing the unit against the wall, then sweep. New users often release the button before the sweep starts and wonder why the readings jump around.
CRAFTSMAN backs the CMHT77633 with a full lifetime warranty, which is rare in this category. If the unit fails, you send it back and they replace it. For a budget tool, that warranty alone can justify the purchase.
Best fit for
Occasional users who only need a stud finder a few times a year. Hanging a curtain rod, a coat rack, or a small shelf. The lifetime warranty means it can sit in a drawer for years and still be useful.
Where it does not fit
Plaster, tile, brick, and concrete are not supported. Live wire detection is not built in, so exercise caution near outlets.
How We Tested the Best Stud Finders?
Our team put each of these stud finders through a series of tests on the same wall sections to compare results directly. We scanned standard half-inch drywall over wood studs, a doubled layer of drywall in a renovation project, a 1940s plaster-and-lathe section, and a tile bathroom wall to check metal and AC modes.
For each model we logged how quickly it found a stud center, whether the reading matched a known stud location, and how many false positives showed up across 10 consecutive scans. We also tested the live wire detection by running scans across known live cable locations and noted whether the unit gave a clear warning before we drilled.
User feedback mattered as much as our own testing. Forum threads on r/HomeImprovement and r/Tools highlighted the same patterns we saw on our test wall: cheap models give inconsistent readings, Franklin units earn consistent praise, magnetic finders win for drywall picture hanging, and plaster walls are a separate challenge from standard drywall.
Stud Finder Buying Guide: What Actually Matters
Magnetic vs Electronic Stud Finders
Magnetic stud finders like the StudBuddy pair use strong neodymium magnets to detect the metal fasteners holding drywall to the stud. They never need batteries, never need calibration, and cannot give a false reading because there is nothing to misread. They work best on standard drywall where screws or nails are evenly spaced.
Electronic stud finders use sensors that detect density changes in the wall material or capacitance shifts near framing. They are the right choice for plaster, lathe, tile, and concrete walls where magnetic detection fails. The trade-off is calibration sensitivity, battery dependence, and the need to learn the unit’s quirks.
For most homes, the answer is to own both. A magnetic finder handles picture hanging and basic tasks in seconds. An electronic unit handles heavy mounting jobs, plaster walls, and any project where you need to know what is behind the wall before drilling.
Center vs Edge Detection
Edge detection tells you where the stud edge is, then you sweep the opposite direction to find the other edge, then you measure between the two marks. That process works but adds time and error to every scan.
Center detection, also called center-find technology, does the math for you and lights up when you are over the middle of the stud. Models like the DEWALT DW0100 use directional arrows to guide you to the center. Multi-sensor units like the Franklin M150, M210, and 710+ show the full stud width at once, which removes the guesswork entirely.
Sensor Count and Scanning Depth
More sensors mean a wider read at one time. The Franklin ProSensor line uses 9 or 13 sensors in a row, which is why those models can show the entire stud at once. Single-sensor models can only tell you what is directly under the unit.
Scanning depth matters on thick walls. Standard 3/4 inch depth handles single-layer drywall. For doubled drywall, plaster, or tile over drywall, look for a model with 1.5 inch or deeper scan modes. The Povlen 5-mode and the Franklin 710+ both push past 1.5 inches.
Live Wire and AC Detection
Live wire detection is the safety feature you hope you never need but should always have. Models like the Franklin M210, the Jurgen K 5-in-1, and the DEWALT DW0100 all include AC detection that warns you when you are scanning near a live wire.
If you are mounting a TV, running cable through a wall, or installing a ceiling fan, AC detection is non-negotiable. Drill into a live wire and you are looking at a tripped breaker at best, an electrical fire at worst.
Wall Type Compatibility
Drywall is the easy case. Every stud finder on this list handles drywall cleanly. Plaster and lathe are a different challenge because the material density varies. Multi-mode units with deep scan and metal mode handle plaster better than single-mode units. Tile and concrete require specialized scanners, which are beyond the scope of consumer stud finders.
Metal stud framing, common in commercial buildings and some modern homes, requires a model that can detect ferrous and non-ferrous metal. Most stud finders on this list handle wood studs and metal studs, but check the spec sheet if your project involves steel framing.
Battery Type and Calibration
Battery type matters more than people expect. Many Franklin models refuse to run on rechargeables, so you need to stock alkalines. The CRAFTSMAN CMHT77633 takes a 9V battery that is not included in the box. Magnetic stud finders sidestep the whole battery question.
Calibration is where budget models fall down. Some units require you to press a calibration button before each scan, and if you forget, the readings are unreliable. No-calibration models like the Franklin ProSensor line and the DEWALT DW0100 with constant auto-calibration remove that error source.
How to Find Studs Without a Stud Finder
If you do not own a stud finder or your walls are unusual, there are three reliable methods to fall back on.
First, use a strong rare-earth magnet. Drag it slowly across the wall in an S-pattern. When it sticks, you have found a drywall screw or nail, which means you are over a stud. This works on standard drywall and is the same principle the magnetic StudBuddy uses.
Second, look for outlet and switch boxes. Electrical boxes are almost always mounted to a stud on one side. The stud is typically on the right side of the outlet as you face it, though that varies by region. From one outlet you can usually measure 16 inches to the next stud.
Third, knock on the wall. A hollow sound means empty space between studs. A solid sound means you are tapping close to a stud. This method is not precise, but combined with the 16-inch on-center spacing rule, it gives you a rough idea of where to start.
Frequently Asked Questions
What type of stud finder is most accurate?
Multi-sensor electronic stud finders like the Franklin Sensors ProSensor M210 and 710+ are the most accurate because they read across the entire stud width at once instead of detecting one edge at a time. For the best results on standard drywall, multi-sensor models with 9 or 13 sensors consistently outperform single-sensor budget units.
What is the best stud finder that actually works?
The Franklin Sensors ProSensor M210 is our top pick for actually working on the first try. Its 13 sensors show the full stud width without calibration, and the live wire detection adds safety for any drilling project. For a budget option, the CRAFTSMAN CMHT77633 handles basic drywall tasks and has a lifetime warranty.
How deep can a stud finder detect?
Most consumer stud finders detect between 3/4 inch and 1.7 inches deep. Standard drywall-only models stop at 3/4 inch. Models like the Franklin ProSensor 710+ reach 1.6 inches and the M210 reaches 1.7 inches, which is enough for doubled drywall and most plaster walls. For thicker surfaces like tile over concrete, you need a specialized scanner.
Do stud finders work through ceramic tiles?
Standard stud finders struggle with ceramic tiles because the tile and adhesive layer create false readings. To scan through tile, you need a multi-mode scanner with metal and deep scan modes, and even then results vary. For bathroom tile projects, consider drilling into grout lines or using anchors rated for tile rather than relying on stud detection alone.
How far apart are wall studs?
Wall studs are spaced 16 inches on center in most modern residential construction, meaning the center of one stud is 16 inches from the center of the next. Some homes use 19.2 inch or 24 inch spacing, especially in older buildings or commercial structures. Measuring from an outlet or switch box is the easiest way to find the first stud, then mark every 16 inches from there.
Is zircon or franklin a better stud finder?
Franklin Sensors is generally considered more accurate than Zircon for stud detection because of its multi-sensor design. The Franklin ProSensor M210, 710+, and M150 all use multiple sensors to show the full stud width at once. Zircon MultiScanner models like the A200 are still solid picks, especially for users who want center-find features and AC detection in a single mid-priced unit.
Final Verdict
After three months of testing, our pick for the best stud finder in 2026 is the Franklin Sensors ProSensor M210. The 13-sensor design shows the full stud width at once, the live wire detection is reliable, and the no-calibration workflow means you spend your time mounting things instead of fighting the tool.
For shoppers who want to spend less, the Franklin ProSensor M150 keeps most of the M210’s accuracy at a lower cost. For anyone hanging a lot of pictures on standard drywall, the Original StudBuddy magnetic finder is faster than any electronic unit. Match the tool to your wall type, not to the brand, and you will spend less time patching drywall and more time enjoying the finished project.
