Question: I need to run some wires in my wall. What is the best stud finder that can also detect electrical wiring?
If you’re going to run wires inside a wall, I’d prioritize a scanner with reliable live-AC detection rather than a basic stud finder.
My picks
Franklin Sensors ProSensor M210 - $73.97 (The Home Depot)
Best overall for a homeowner: Franklin Sensors ProSensor M210. It uses 13 sensors to show the width/center of studs and has a dedicated live-wire meter. Popular Mechanics’ 2026 testing also rated it its best overall stud finder.
Bosch GMS120-27 Digital Wall Scanner - $119.00 (The Home Depot)
Best if electrical detection is the priority: Bosch GMS120-27. It detects wood/steel studs, metal, and live wires, and is more of a general-purpose wall scanner than a simple stud finder.
When you are running wires inside a wall, you need more than a basic gadget that just pings when it finds a piece of wood. You need a dependable multi-surface wall scanner that can clearly flag live electrical lines so you don't accidentally drill into or clip a hot wire.
The top options on the market that excel at combining accurate stud/object detection with reliable live AC wire warning include:
Why it's great: Unlike traditional single-sensor models that require tedious sliding and calibration, the M210 uses to display the entire width, edges, and center of a stud instantly. It also features a dedicated, highly responsive system that alerts you to active AC electrical lines. It’s fast, incredibly accurate on drywall and plaster, and virtually eliminates false positives.
Question: I need to run some wires in my wall. What is the best stud finder that can also detect electrical wiring?
Good less-expensive option: Franklin X2100. It specifically combines electric, metal, and wood detection and is currently around $63 in the product results.
One important warning
Don't treat a stud finder’s “no wire detected” result as proof that it is safe to drill. These devices primarily detect the electromagnetic field from energized AC wiring, and testing has shown that some wiring configurations can escape detection.
For your project, I would:
Scan the wall in multiple directions and mark both studs and any wire warnings.
Check from both sides of the intended drilling/cutting area.
Turn off the relevant breaker before cutting into the wall.
Verify the circuit is actually de-energized with an appropriate electrical tester.
Be especially cautious around outlets, switches, and electrical boxes.
If you're cutting a channel in the drywall to run new cable, rather than just drilling a couple of holes, tell me what type of wire you're installing (Romex, Ethernet, speaker wire, etc.) and whether the wall is drywall or plaster. I can recommend the safest tool and method for that particular job.
Walabot
When you are running wires inside a wall, tracking down live AC electrical wiring alongside wood or metal framing is critical for safety. Standard single-sensor or basic magnetic stud finders won't catch live electrical currents, so you need a multi-mode digital wall scanner or a dedicated radar device.
Top options on the market equipped with reliable live wire detection include:
[Bosch GMS120-27 Wall Scanner ](https://www.amazon.com/Bosch-Wallscanner-Professional-Detection-Intuitive/dp/B00PJ2Q1JI) : Widely considered the gold standard for serious DIYers and pros. It features dedicated multi-detection modes for wood studs, metal (rebar, steel, copper), and live AC wiring. It uses a color-coded illuminated ring (red for stop/hazard, green for clear) and an audible signal to keep you safe.
[Zircon MultiScanner A200 ](https://www.amazon.co.uk/Zircon-MultiScanner-Electronic-Detector-Detection/dp/B09CVCZD1W) : Known for its patented WireWarning technology, which actively scans for live, unshielded electrical AC wiring in all modes—not just a specialized AC setting. It also features a SpotLite pointer to clearly project where the target edge is located.
Pro-Tip: Consumer-grade stud finders can sometimes struggle to pick up low-voltage lines or wires shielded inside metal conduit. Always treat AC warnings as absolute, and double-check high-risk zones with a dedicated non-contact voltage tester before cutting into drywall.
Are you planning to fish the wires through drywall or plaster , and do you need recommendations based on a specific budget?
When running wires inside a wall, finding wood/metal studs and safely avoiding live electrical cables is a priority. Traditional single-sensor stud finders can be finicky, but several multi-sensor and advanced wall scanners excel at both accurate stud mapping and reliable live AC wire detection.
Top options on the market for dual stud and electrical wire detection include:
Add to list Franklin Sensors ProSensor M210 — Widely considered one of the best overall choices for accuracy. It uses multiple sensors (13 separate sensors) to map the entire width of a stud instantly without calibration . Crucially for your project, the M210 features an integrated live wire warning meter right alongside its LED stud display.
Bosch GMS120-RT Digital Wall Scanner
Bosch GMS120-RT Digital Wall Scanner — A professional-grade multi-detection tool. It doesn't just find wood studs; it accurately detects metal (rebar, copper, steel studs) and live electrical cables with deep scanning capabilities and an illuminated display.
Add to list Zircon MultiScanner A200 — A trusty multi-purpose scanner that features auto-correcting technology (ACT) to reduce user error. It includes a dedicated WireWarning detection mode that flags live, unshielded AC electrical wiring across its scanning ranges.

Note: Standard budget models like the popular Franklin Sensors ProSensor 710 are fantastic for finding studs, but they do not feature live wire detection. Make sure you grab a model explicitly built with an AC/wire meter.
If you want to narrow this down, tell me:
What type of walls are you scanning (drywall, plaster, lath)?
Are you looking for a budget-friendly handheld unit or a high-tech visual scanner?
I can help you pick the exact tool or share tips on how to fish your wires safely.
Franklin Sensors
If your main goal is finding studs while also warning you about electrical wiring, I’d pick the Zircon MultiScanner HD900c.
Zircon MultiScanner HD900 - $59.97 (The Home Depot)
My picks
Best overall for wiring work: Zircon MultiScanner HD900/HD900c — It specifically has AC Scan and WireWarning, detects live, unshielded AC wiring up to about 2 inches deep, and can locate wood/metal studs and metal pipe. The newer HD900c adds a color display that makes the different scan modes easier to interpret.
Best stud-finding experience: Franklin Sensors ProSensor M210 — 13 sensors and a wide LED display show the whole stud, rather than just an edge, and it has a live-wire meter.
Zircon MultiScanner HD900 - $59.97 (The Home Depot)
Franklin Sensors ProSensor M210 - $73.97 (The Home Depot)
Bosch GMS120-27 Wall Scanner - $119.00 (The Home Depot)
Franklin Sensors X2100 - $62.98 (Lowe's)
For your specific project, I'd spend the extra money on the Zircon. Its dedicated AC scanning is particularly useful when you're about to cut into a wall.
One important caveat: no stud finder should be treated as proof that a wall is safe to cut. These detectors can miss wires that are deeper than their detection range, shielded by conduit/metal, or not energized. Zircon specifically warns not to rely exclusively on the detector and recommends turning off power when working near electrical wiring.
If you're cutting a hole to run Ethernet/coax/low-voltage wire, I can also tell you the safest way to map the wall first—including where electrical wires are most likely to run.
Why it's great: This is a heavy-duty multi-detection tool favored by pros. It doesn't just find wood studs; it actively scans for wood, ferrous metals (rebar, steel), non-ferrous metals (copper pipes), and live electrical cables . It features automatic calibration and an illuminated display with an audio signal to pinpoint the exact location of hidden hazards.
Why it's great: Zircon is a household name for wall scanners, and the A200 steps things up with deep-scanning metal detection and WireWarning® detection which flags live, unshielded AC electrical wiring across all scanning modes. It also includes an auto-correcting technology to fix common user starting errors and a SpotLite pointer to clearly mark the target.
Why it's great: If you want a high-tech visual approach, the Walabot connects to your smartphone (iOS or Android) and uses advanced radio frequency radar to literally "see" inside your drywall . It maps out a visual image of studs, pipes, and live wires up to 4 4 4 inches deep, making it fantastic for complex projects like routing wires.[1][2]
A Quick Pro-Tip for Running Wires
Electronic stud finders with AC detection are great for a warning, but they rely on the electrical wire being live and carrying a current to pick up the electromagnetic field. If a wire is dead or shielded tightly, it might not trigger the sensor. Always exercise caution and consider backing up your wall scanner with a cheap, non-contact voltage tester if you plan on cutting deep into drywall near outlets or switches.
To help narrow down the best choice for you, tell me:
Are you working on standard drywall , or something thicker like plaster or lath?
Do you also need to watch out for pipes (plumbing/gas), or just electrical wires?
Walabot
If you’re going to run wires through a wall, I’d spend a little more on a wall scanner that explicitly detects live AC wiring, rather than a basic stud finder.
My picks
Bosch GMS120-27 Wall Scanner - $119.00 (The Home Depot)
Best overall: Bosch GMS120-27 — about $119. It detects wood/steel studs, metal, and live wires. Bosch rates its live-copper-wire detection to 2 inches deep, and it gives you a center indication for studs.
Zircon MultiScanner HD900 - $59.97 (The Home Depot)
Best value: Zircon MultiScanner HD900 — about $60. It finds stud centers, metal, and live electrical wiring, with an AC scan mode.
Walabot DIY 2 - $229.95 (Best Buy)
Best high-end option: Walabot DIY 2 — about $220. It uses a phone-connected imaging system and can visualize studs, pipes, and wiring rather than simply giving you a warning.
What I'd buy
For actually routing new electrical/network wires, I'd choose the Bosch GMS120-27. It's a good middle ground between a $20–$30 stud finder and expensive professional radar scanners.
One important caveat: don't treat any stud finder as proof that a wall is safe to drill into. Wire-warning systems generally detect live, unshielded wiring, so a de-energized wire or wiring shielded by certain materials may not be detected. Zircon specifically says its WireWarning feature is intended as a warning, not as a precise wire locator.
If you're cutting/drilling the wall, I'd turn off the relevant breaker(s) and use the scanner in multiple directions before making the opening.
If you tell me what kind of wall you have (drywall, plaster, etc.) and whether you're running electrical, Ethernet, coax, or speaker wire, I can recommend the best scanner and the safest way to route it.
The overall best stud finder that detects live electrical wiring is the Franklin Sensors ProSensor M210 . It uses a 13-sensor array to instantly show the entire width of a stud without needing calibration, and it features a dedicated, highly accurate live wire meter.[1]
Top Recommended Models
For a project involving routing wires through walls, you need a balance of fast stud mapping and deep AC voltage detection. The best options on the market depend on your specific needs:
Add to listBest Overall:Franklin Sensors ProSensor M210 . It has 13 precision sensors that track wood and metal studs simultaneously. The LED display lets you see the center and exact boundaries of the studs in real-time while monitoring live wires.[1]
Do not rely entirely on a stud finder's wire detection feature. Most stud finders only detect live, unshielded AC electrical lines . They will not pick up wires if the circuit breaker is turned off, if the wires are low-voltage (like internet/coaxial cables), or if they are housed in metal conduit. Always turn off the power at the breaker panel before cutting into or drilling through walls.[1]
If you would like to narrow this down, please let me know:
Your approximate budget
The wall material (standard drywall, plaster and lath, or concrete)
What type of wires you are trying to install (low-voltage ethernet/audio vs. standard electrical lines)
Zircon
If you’re running wires in a wall, I’d prioritize a stud finder that can detect live AC wiring and has reliable stud locating—not just a cheap magnetic stud finder.

Before you run wires, a few safety tips
Use the stud finder with the circuit energized first so it can detect live wiring, then turn the breaker off before cutting or drilling.
Don’t assume “no signal” means “no wire.”
Avoid drilling directly in line with outlets and switches; wires often run vertically from them.
For new cable runs, use proper protection (such as nail plates) if a cable passes through a stud where it could be hit by screws or nails.
If you’re fishing low-voltage cable (Ethernet, HDMI, speaker wire) versus new 120V electrical cable, the best tool choice and precautions are a little different.
The overall best stud finder that detects live electrical wiring is the Franklin Sensors ProSensor M210 . It uses a 13-sensor array to instantly show the entire width of a stud without needing calibration, and it features a dedicated, highly accurate live wire meter.[1]

If you’re going to run wires through a wall, I’d spend a little more on a good scanner rather than buying a basic stud finder.
🏆 Best overall: Franklin Sensors ProSensor M210
Franklin Sensors ProSensor M210 - $73.97 (The Home Depot)
This is the one I’d buy for a typical drywall project. It has 13 sensors, shows the full width of the stud, detects wood and metal studs, and has a dedicated live-wire meter. It scans to about 1.7 inches deep and doesn't require calibration.
The big advantage is that you're not just getting a beep when you cross a stud—you can see its edges and center, which makes laying out your drilling/cutting locations much easier.
🥈 Best if electrical detection is your priority: Bosch GMS120-27
Bosch GMS120-27 Wall Scanner - $119.00 (The Home Depot)
I'd choose this if you're dealing with thicker/complex walls or want more comprehensive material detection. It has separate detection modes for wood, metal and live AC wiring. It's more expensive, but it's a more sophisticated wall scanner.
🥉 Good alternative: Zircon MultiScanner A200
The A200 is a good middle ground, with wood, metal, deep-scan and live-AC modes and a useful center-marking system.
⚠️ One important warning
Don't treat the wire-detection feature as proof that an area is safe to drill. Electronic stud finders can miss wires, particularly depending on wire orientation, depth, wall material, and whether the conductor is energized. Franklin's own instructions specifically warn that its live-wire detector may not detect all live wires and recommend scanning in multiple directions.
If you're actually cutting into the wall or drilling deeply to run new electrical cable, I'd use the scanner to map the area, then turn off the appropriate circuit at the breaker and verify that it's de-energized with an appropriate voltage tester before penetrating the wall.
My pick: Get the ProSensor M210 for about $60. It's the best combination of easy stud finding + useful live-wire warning for ordinary drywall.
