Overview
Not a magnetic screw finder, the Franklin ProSensor uses a row of sensors to light up the full width of each stud behind drywall. It needs no calibration, so you press the button and slide, even starting over a stud.
Seeing both edges at once makes it easy to find stud centers, double studs and odd framing. It needs standard alkaline cells, and scan depth is limited to typical drywall.
Who it's for
DIYers and installers who want quick, confident stud locations for hanging heavy items. People working through very thick wall coverings may need a deeper scanning tool.
Pros and cons
- Shows full stud width
- No calibration step
- Finds wood and metal studs
- Built-in level and ruler
- Batteries not included
- No rechargeable batteries
- Limited scan depth
Performance notes
Multiple sensors read density across the tool's width, so the LED row maps where a stud starts and ends in one pass. Thicker or denser wall layers reduce how clearly the edges show.
