The StudSensor™ e40 quickly and easily locates the edges of wood and metal studs and joists behind walls, floors, and ceilings. It features a new user-friendly interface. An improved SpotLite® Pointer shines a beam of light on the wall to identify the target and WireWarning® detection indicates the presence of live AC voltage. Its new patent-pending pinch grip and contoured shape provide an easy, secure hold in either hand, at any angle.
- Locates the edges of wood or metal studs up to 3/4 inch (19 mm) deep
- DeepScan® mode doubles the scanning depth to 1 1/2 inches (38 mm)
- New "Ready" light indicates when calibration has completed successfully
- Red arrows light up sequentially as the stud finder nears a target
- New "Edge" light indicates when the tool is over a stud edge
- Updated SpotLite® Pointer shines an arrow-shaped light on the wall to mark the target
- WireWarning® detection indicates the presence of live, unshielded electrical wiring up to 2 inches (51 mm) deep
- Should scanning begin over a stud, Zircon's patented "over-the-stud" indication alerts the user to start the scan in a new location

Find Stud Edge
Stud finders work by measuring density. Your wallboard is one density; when the stud finder registers a higher density as you slide the tool along the wall, it probably means you've reached the edge of a stud. To find the center of the stud, you must find both edges first
Scan Thick Walls for Studs
Sometimes because of extra layers of wallboard or paneling, the studs are too deep to be found by standard scanning.
Tools with Zircon's Deepscan® feature can be switched to a higher strength to detect studs and joists up to 1 1/2 inches deep.
This extra power shouldn't be used unless necessary, because on normal walls it is oversensitive and results in too many false positives.
WireWarning® Detection
Tools with the WireWarning® detection feature continuously detect hot electrical wires (unshielded) up to 2 inches deep while you are scanning for studs or metal. WireWarning® detection is always on, in Stud, DeepScan®, and Metal modes, to alert you to the presence of hot, unshielded AC wires behind the wall.
