Franklin Sensors ProSensor M210 13-Sensor Stud Finder — Live Wire Detection, Full-Width LED Mapping

The Franklin Sensors ProSensor M210 is a 13-sensor stud finder that maps full stud widths, locates live wires, and gives fast, calibration-free readings for drywall and plaster walls.

The ProSensor M210 replaces guesswork with a wide, multi-sensor scanning panel that clearly shows stud edges and centers at once. Designed for professionals and DIYers who want a reliable, repeatable way to place anchors, hang cabinets, or run wiring, this compact tool uses an array of sensors to produce an intuitive LED map rather than a single pinpoint. It also includes extras like a built-in bubble level, live wire alert, and a pencil holder so you can mark positions quickly.

How does the M210 find studs more accurately than single-sensor finders?

Instead of relying on a single sensor to infer stud location, the M210 uses thirteen sensing elements across a wide contact face. This produces a continuous visual band showing the whole stud and makes double-stud detection straightforward.

• 13 independent sensors reduce false positives across seams and textured surfaces
• LED array displays the full stud width and gradual edges
• Center LED lights green to highlight stud centers for drilling or screwing

Can it detect live electrical wiring and different stud materials?

The M210 includes live wire detection that alerts you to AC voltage beneath the surface, helping you avoid contact with powered cables. It detects both wood and metal studs and scans up to about 1.7 inches deep, making it suitable for standard drywall, plaster, and furring applications.

• Live wire indicator for AC voltage presence
• Deep detection mode reaches up to approximately 1.7 inches
• Works on wood and metal studs without re-calibration

What makes the M210 easy to use on the job or at home?

Operation is simple: press and hold the power button and slide the unit laterally—no calibration steps or test holes are required. The broad scanning surface and clear LED readout reduce the need for repeated passes, and a built-in level and pencil caddy keep necessary tools at hand.

• No calibration—begin scanning anywhere, even over a stud
• Built-in bubble level helps ensure straight installations
• Pencil caddy stores a marking pencil for quick placement

How durable and power-efficient is the device for regular use?

The ProSensor M210 is built for workshop and field use with a rugged housing and straightforward controls. It runs on two AA batteries (not included) and is compatible with rechargeable cells for cost-effective, repeated use.

• Rugged casing suited for jobsite handling
• Operates on two AA batteries; accepts rechargeables
• Simple single-button operation reduces wear points

Who is this for: The Franklin Sensors ProSensor M210 is aimed at tradespeople, remodelers, and informed DIYers who need faster, more reliable stud location without the hassle of calibration. If you hang cabinets, mount TVs, install shelving, or run low-voltage lines and want to minimize drilling mistakes and time spent re-checking placements, the M210 provides a clear, repeatable view of stud layout and potential live wiring hazards.
