Zircon StudSensor i65 OneStep Center Finding Stud Finder with Wire Warning The Zircon StudSensor i65 is a center finding electronic wall scanner. Using the patented CenterVision technology, the SS i65 easily locates the center and edges of wood and metal studs and joists behind walls, floors, and in ceilings with just one pass. The specialized SpotLite Pointing System and an audio tone indicate the location of the target. In StudScan mode, the SSi65 locates the center and edges of shallower wood or metal studs up to 3/4 of an inch (19 mm) deep. Switch over to DeepScan mode by quickly pressing the Power Button twice to double the scanning depth to 1.5 inches (38 mm). This stud sensor is programmed with a WireWarning Detection feature that indicates the presence of live unshielded electrical wires up to 2 inches (50 mm) deep when using both stud scan modes. To get started, install one brand new 9V alkaline battery (not included). Place the unit flat against the wall and press the Power Button to calibrate the sensor. Once you hear a beep indicating calibration is complete, continue to hold the Power Button and slowly slide the tool across the surface. The Signal Strength Bars will appear on the LCD screen when a stud is detected. As the stud finder detects the edge of a stud, ?EDGE? will appear in the LCD screen. Continue to slide the tool along the wall until you hear an audio tone and see both the SpotLite Pointer as well as ?CENTER? on the LCD. These signs indicate the center of the stud has been found. Make sure to note whether the WireWarning Detection is alerting to live, unshielded AC wiring before drilling into the center of the stud. With the Zircon StudSensor i65, you can safely maneuver through the most complicated of projects with the professional confidence that comes from owning a Zircon.
