Q: How wide of an area does this stud detector scan?
It's 7 inches wide and uses 13 independent sensors, so it covers a broad section of wall in a single pass instead of requiring several narrow sweeps.
88N8721 - Franklin M210 Stud Detector
This is a remarkable stud sensor. Not only is it easy to use, but its readings are practically impossible to misinterpret. At 7" wide, it covers a broad test area, with sensors that independently scan up to 1 1/2" below the surface. As soon as any of the 13 sensors detects material of greater density than the surroundings, they display its position using 21 closely-spaced red LED bulbs, highlighting precisely where the obstruction lies.
Wide enough to span most structural timbers, the LED array can indicate the full width of the stud, not just the edges, so finding center is simple – no need to sweep back and forth to outline the location. As well, unlike typical detectors, the sensors require no calibration before each use to prevent false readings; just place the unit against the wall and press the button for an instant reading.
A reliable means to locate studs as well as floor joists or other hidden substructure behind drywall, wood and plywood, it even differentiates closely positioned studs, such as those around door and window frames. It also detects live electrical wires behind walls. A low-friction backing glides smoothly over surfaces, and a built-in level helps with marking.
Intuitive to use, it operates on two AA batteries (not included). An excellent tool.

No, this detector doesn't require calibration before each reading. Hold it against the wall and press the button for an instant result.
Yes, it also detects live electrical wires behind walls in addition to studs, joists and other hidden substructure.
The Franklin ProSensor M210 runs on two AA batteries, which aren't included, so keep a spare pair on hand.
Each of its 13 sensors can detect material up to 1 1/2 inches below the surface, which is enough depth to reliably locate studs and joists behind drywall, wood or plywood.
