Franklin Sensors ProSensor M70 7-Sensor Stud Finder
Best for
This is for anyone who wants one stud finder that just works, whether the wall behind it is drywall, plaster, or old lath. If you're deciding between spending under $20 here or several hundred dollars on the Bosch D-tect, you'd only regret the Bosch unless you're working through tile or concrete daily.
Why we love it
Seven sensors read the full width of a stud instead of guessing from a single edge, which is why this consistently outperforms single or dual sensor units on drywall, plaster, and lath alike. Unlike the StudBuddy, which only finds the screw holding the drywall on, the middle LED here lights up green right over the stud's true center, so there's no interpreting a magnet's tug. It needs no calibration: press and hold, and it reads accurately even starting directly over a stud. Deep scan is always on up to 1.5 inches, and it runs on two AAA batteries with a low battery indicator so it doesn't die on you mid job. At under $20, it costs a fraction of the Bosch D-tect 120 while nailing the one job most people actually need a stud finder for.
Pros
- Seven sensors read the stud's full width, not just one edge
- No calibration required, scan starts anywhere on the wall
- Deep scan up to 1.5 inches finds both wood and metal studs
- Runs about $20, far less than radar based scanners
Cons
- No live wire detection, unlike Zircon's WireWarning feature
- Not rated for the extra depth of tile or masonry work
- Requires two AAA batteries and is not compatible with rechargeables
Verdict
Yes, for nearly every home project this is the stud finder to own. If you're scanning through tile or need radar level depth for concrete, step up to Best for Tile and Pro Jobs. Otherwise this outperforms pricier options for standard walls.
StudBuddy Pro Magnetic Stud Finder with Level
Best for
This is for anyone hanging a single picture frame or floating shelf who doesn't want to think about batteries or calibration. If you're outfitting a whole house or working on plaster, you'd regret stopping here instead of stepping up to the Franklin ProSensor.
Why we love it
Neodymium magnets find the actual screws holding your drywall to the stud, so there's no ambiguity once it sticks. Unlike the Franklin ProSensor, it needs zero batteries and zero calibration, you just slide it across the wall until it grabs. Felt pads on the case protect paint and wallpaper while you search, and the built in level means you can mark a straight vertical line the moment it locks on. At under $17, it costs a fraction of any electronic sensor on this list, and it will never wear out or need replacing the way batteries do.
Pros
- No batteries or calibration required, ever
- Felt padded case protects paint and wallpaper
- Built in level marks a straight line once it locks on
- Costs a fraction of any electronic sensor here
Cons
- Finds only the fastener, not the stud's true edges
- Not intended for lath and plaster walls
- Less effective once nails sit deeper than standard drywall
Verdict
Yes, if you're hanging light to medium items on standard drywall and want the simplest possible tool. Skip it for plaster or lath walls and get the Zircon or the Franklin instead, since a magnet can't find a fastener that isn't there to find.
Zircon StudSensor Pro LCD Stud Finder with DeepScan
Best for
This is for buyers who want deep scan and wire warning features without paying professional radar prices. If you have true lath and plaster instead of thick drywall, you'd regret this pick and be better served by the Bosch D-tect or a sensor explicitly rated for plaster.
Why we love it
The DeepScan setting extends detection up to 1 1/2 inches, matching the Franklin ProSensor's depth while adding a WireWarning alert for hot electrical wiring that the Franklin doesn't have. It's widely stocked at big box stores, so replacing or comparing units is easy if a reading seems off. The LCD display gives a clearer visual readout than a simple LED bar, which helps on trickier walls where you're triangulating a stud's exact center. At $36.99, it sits comfortably between the budget magnets and the professional radar scanners on this list.
Pros
- WireWarning alert flags live electrical wiring the Franklin lacks
- LCD readout is easier to read on tricky walls than a basic LED bar
- 1 1/2 inch DeepScan depth handles most thicker drywall and paneling
- Widely available at hardware and big box stores
Cons
- The manufacturer does not recommend it for lath and plaster, despite the deep scan branding
- Some users report newer DeepScan models feel less sensitive than older Zircon units
- Costs nearly double the Franklin for similar maximum depth
Verdict
Buy it if you want wire detection and don't mind paying more than the Franklin for similar depth. If your walls are genuinely old plaster and lath, this isn't rated for that job, so look at the Bosch D-tect instead.
Bosch D-tect 120 Professional Wall Scanner
Best for
This is for contractors and serious renovators who need to find studs, pipes, and live cables behind tile, concrete, or other dense finished surfaces where a standard sensor can't read through. If you're working on ordinary drywall, you'd be overpaying compared to the Franklin ProSensor, which several redditors say performs just as well for routine jobs.
Why we love it
Bosch's radar technology reads through up to 120mm of non-magnetic metal or live cable and 38mm of wooden studs, detection depth that no other pick on this list comes close to matching. Three detection settings, drywall, concrete, or universal, let you tune the scan to the actual material instead of guessing, and it worked well on a tricky tile job that stumped simpler tools. It runs on either a 12V Li-ion battery or standard AA batteries, so a dead battery on a job site doesn't stop you cold. At $234.19, it's more than ten times the price of the Franklin ProSensor, and that gap is the honest tradeoff for radar depth most homeowners will never need.
Pros
- Radar reads up to 120mm through metal, cable, and dense material
- Three material specific detection settings: drywall, concrete, universal
- Works through tile and other finished surfaces standard sensors can't read
- Dual power source keeps you working if one battery type runs out
Cons
- Costs over $200 more than the Franklin for jobs that don't need radar depth
- Several redditors found cheaper Franklin sensors performed just as well for typical jobs
- Steeper learning curve than a single button electronic sensor
Verdict
Buy it only if you regularly work through tile, concrete, or need cable detection on the job, since the price is hard to justify otherwise. For everyday drywall and plaster, the Franklin ProSensor or the Zircon deliver comparable accuracy for a fraction of the cost.
Frequently Asked Questions
Do magnetic stud finders work on plaster walls?
Not reliably. Magnetic finders like the StudBuddy locate the screws or nails fastening drywall to a stud, and older plaster and lath construction often uses nails set deeper or spaced less predictably, so an electronic sensor rated for plaster is the safer choice there.
How deep can a stud finder detect through a wall?
Standard electronic sensors typically read up to about 1.5 inches, which is enough for drywall and most interior walls. Radar based scanners like Best for Tile and Pro Jobs can read several inches deeper, which is what makes them worth it for tile, concrete, or thick masonry.
Are expensive stud finders actually worth the extra cost?
Only if your walls demand it. A premium radar scanner earns its price on tile, concrete, or commercial jobs, but on ordinary drywall a sub $20 multi sensor unit like Best Overall reads just as accurately for a fraction of the cost.
Why do two stud finders give different readings on the same wall?
Single sensor models can be thrown off by wiring, moisture, or paint texture, and give a false edge instead of the stud's true width. Multi sensor tools reduce this by reading the whole span of the stud at once, which is why cross checking with a second, more sensitive tool is common practice among people who need to be sure.
Honorable Mentions

See PriceAmazonShinwa Sokutei 79026 Needle-Type Stud and Screw Detector
Pairs a piercing needle with a magnet for direct physical confirmation of a screw or ferrous stud rather than an electronic guess, though it won't find non-ferrous items like deeper conduit.
