The ProSensor M155 Stud Finder delivers high-accuracy stud detection with 9 precision sensors—far more than conventional stud finders that typically use only 1 or 2. With more sensors reading changes in wall density, the M155 finds studs more reliably and requires no calibration, so you can start scanning immediately.

Its precision LED display (15 LEDs) shows the full width of studs, including double studs and irregular configurations that many stud finders can miss. For safer work, it also includes a live wire meter, and the center stud indicator makes fastening more accurate—the middle LED turns green when you’ve found the stud’s center. With a 1.5″ detection depth and Made in the USA build quality, the ProSensor M155 is a dependable upgrade for pros and DIYers alike.
