The Franklin Sensors ProSensor M150 Stud Finder with Live Wire Detection, 9-Sensor Wall is one of our picks for the measuring tool lineup. Everything below comes straight from the manufacturer's published listing - specs, capacities, and dimensions are theirs, not ours.
Layout starts with measurement you can trust: a locking 25-foot tape is the universal jobsite unit, and a stud finder with live-wire detection is a safety tool as much as a convenience - drilling blind into a live cable is a preventable incident. For lines and levels at room scale, the laser level collection picks up where the tape stops.
Key details, quoted from the manufacturer's published listing:
- ACCURATE: More sensors = More accuracy. Conventional stud finders have 1 or 2 sensors. The ProSensor M150 has 9, making it the most accurate stud sensing tool on the market.
- EASY: One mode finds it all! The ProSensor M150 adjusts for a variety of depths, materials, and textures. No calibration required. Press and hold the button to begin scanning. The ProSensor M150 allows you to start scanning anywhere, even over a stud.
- DISPLAYS FULL STUDS: The LEDs show the whole stud, double studs, and irregular configurations.
- DEEP DETECTION: The ProSensor M150 has a max detection depth of 1 1/2 through drywall/sheetrock and more.
- EXTRA FEATURES: Live Wire Detection. Two AAA batteries required, not included. NOT compatible with rechargeable batteries.

What to check before you buy
Selection starts with the published rating, not the marketing headline. Match the working load, wattage or rating to the manufacturer’s published number, confirm the standard and edition printed on the unit, and treat any listing that hides its rating as a reason to keep shopping.
- Blade standout and hook play
- Standout is how far a tape extends unsupported before it collapses - the practical limit for solo measuring. The hook is designed to move by its own thickness; that play is correct, not a fault.
- Accuracy class
- Tapes are manufactured to accuracy classes. For fine work, mixing tapes from different classes across a job introduces cumulative error.
- Readability in the conditions
- High-contrast markings and the right units for your trade matter more day to day than headline length.
- One tape per job
- Small differences between tapes compound across a layout. Marking out with the same tape throughout avoids chasing errors that are not there.
