Editor's Review: Simple Stud Finder is a Proven Performer
review date: November 8, 2012
The new ProSensor 710 from Franklin Sensors is proof that stud finders, like mousetraps, can always be improved. Unlike other basic models that require endless back-and-forth scanning and a host of smudged pencil marks to locate the edges of a single stud, the ProSensor 710 can display the full width of a hidden object—or multiple objects—the moment it’s placed on a surface.
The secret lies inside the 3-in. by 7-in. unit, where multiple sensors eliminate the need to initialize the tool over a hollow portion of a wall. Once an object is detected, 13 evenly spaced LEDs illuminate individually to display its location. I tested the tool under a variety of conditions, and it turned in above-average scores for accuracy and detection depth. I also appreciated its silence; there’s no annoying beep.
Despite its strengths, this $50 tool is still a basic stud finder. It cannot detect live AC wiring, and it can’t tell the difference between studs, copper water lines, or electrical conduit. If you need that information, you’ll want a capable multiscanner.
