Franklin Sensors ProSensor M90 Stud Finder – 9-Sensor Wall Scanner for Wood & Metal (Made in USA)

Overview

The Franklin Sensors ProSensor M90 redefines wall scanning with a nine-sensor array, delivering broader coverage and more reliable readings than traditional single- or dual-sensor tools. Built in the USA, this model emphasizes consistency and ease of use, helping you locate studs with confidence across a variety of walls.

Why 9 sensors matter

More sensors translate to a clearer, more informative wall map. The M90 doesn’t just mark a point; it traces the center and edges of studs, revealing single, double, and irregular configurations that other detectors might miss. The result is a more complete picture of what lies beneath your surface, from plaster to drywall and textured finishes.

• 9-sensor array delivers broader coverage for accurate stud mapping
• LED indicators show stud center and edges for precise placement
• Detects density changes from wood or metal without extra buttons

Always-on, 1 1/2" deep scan

Scan depth is always on at 1 1/2 inches, with a mode designed to adapt to different depths, materials, and textures. No calibration is required—just press and hold to start scanning, and you can begin over a wall without guesswork. This simplicity helps reduce time spent locating secure anchoring points.

• 1.5-inch-depth scan for reliable detection through common wall coverings
• No calibration needed; start scanning anywhere with a single press
• Simple operation reduces setup time on task sites

What you can expect in real use

Whether you’re hanging art, mounting a TV, or installing shelving, the M90 provides a practical, non-destructive way to locate studs. The full-width view offered by the LEDs helps you plan anchors that are aligned with structural supports, rather than relying on guesswork.

• Clear mapping of stud centers and edges for secure mounting
• Effective through drywall and textured surfaces
• Two AAA batteries power the sensor (batteries not included; rechargeable batteries are not compatible)

Built to last

With a focus on real-world reliability, the ProSensor M90 emphasizes straightforward maintenance and dependable performance. Its USA-made construction reflects a commitment to quality and everyday durability for DIY enthusiasts and professionals alike.
