Franklin Sensors ProSensor M150/X990 Stud Finder with Live Wire Detection – 9 Sensors, Made in USA

Meet the ProSensor M150/X990: smarter sensing for wall projects

The Franklin Sensors ProSensor M150/X990 blends a nine-sensor array with straightforward operation to help you locate studs behind walls with confidence. Instead of relying on a single sensor, this model distributes detection across multiple points, offering a clearer map of framing behind drywall, plaster, or other common wall materials. It also includes Live Wire Detection, so you can check for electrical hazards as you work, adding a layer of safety to daily tasks such as mounting fixtures or planning renovations.

Why this design matters

• More sensors mean broader coverage and a more detailed reading of studs, including variations in spacing or edge conditions.
• A single-mode operation eliminates the need for calibration, letting you start scanning right away and move quickly through setup.
• LED indicators reveal the full extent of a stud, including edges, centers, and irregular configurations, helping you plan mounting positions with fewer guesswork moments.
• Deep detection can reach up to about 1 1/2 inches through drywall, enabling you to locate studs behind thicker wall sections before you drill.

What you can expect in real-world use

Designed for wood and metal studs, the ProSensor M150/X990 is well suited for hanging shelves, mounting televisions, or installing wall art where accurate stud placement matters. It is built for quick, practical use in everyday projects—no fancy setup, just reliable feedback.

• Live Wire Detection adds an extra layer of awareness when you plan penetrations or fixtures.
• Two AAA batteries power the unit (rechargeable batteries are not recommended), keeping you on the job without frequent replacements.
• Made in the USA, reflecting careful manufacturing and sturdy construction designed for routine DIY projects and occasional professional tasks.

Tips for best results

• Hold the trigger and scan slowly to allow the LEDs to map out the studs and edges clearly.
• Scan over different wall textures or near electrical outlets to confirm consistent readings before drilling.
• Use the LED display to mark stud centers and avoid misalignments when mounting heavy items.

With its combination of deep detection, a comprehensive sensor array, and practical features, the ProSensor M150/X990 offers a compelling option for users who want a straightforward, fast way to locate studs and identify potential electrical hazards behind walls.
