Multi-Functional Wall Scanner with ColorTrip Display The Zircon L550C MultiScanner OneStep vibrantly locates studs, metal, and live AC electrical wiring behind walls, floors, and ceilings. The advanced ColorTrip display lights green in stud scan, blue in metal, and red in live AC scan. Screen flashes, or lights red, to alert the presence of live AC in Stud, DeepScan, and Metal Scan modes. A 4-mode switch makes it easy to change modes, while the ultra-bright display screen, patented SpotLite Pointer, and audio tone all indicate the location of the target. Features: StudScan mode locates the centre, edges, and direction of wood or metal studs up to 19 mm deep DeepScan mode doubles the scanning depth to 38 mm deep WireWarning Detection indicates the presence of live, unshielded AC electrical wiring up to 50 mm deep Metal Scan mode locates non-ferrous metal, such as copper pipe, up to 38 mm deep, and ferrous metal, such as rebar, up to 75 mm deep AC Scan mode locates live, unshielded AC electrical wiring up to 50 mm deep ACT (Auto Correcting Technology) automatically corrects common errors, such as when scanning begins over a stud ColorTrip display indicates the direction and edge of the stud and illuminates when the centre of the stud is detected Low Battery Indicator for optimum performance Signal Strength Indicator helps to distinguish between shallow and deep targets SpotLite Pointer shines an arrow-shaped light on the wall to clearly indicate the centre of the stud “V” marker groove for more accurate marking of target location Rubber handle for non-slip grip Specification: Dimensions: 196 mm H x 84 mm W x 43 mm D Battery Type: 9V Alkaline (not included) Position Accuracy: Up to a depth of 19 mm: Typically within 3 mm Up to a depth of 38 mm: Typically within 5 mm In Metal Scan mode: Typically within 13 mm using the dual scan and mark procedure Depth:  StudScan mode: Up to 19 mm DeepScan mode: Up to 38 mm Metal Scan mode: Up to 38 mm for copper, up to 76 mm for rebar AC & WireWarning Position Accuracy: Typically 90-250 V at 50-60Hz within 152 mm of a hot, unshielded wire in drywall AC & WireWarning Depth: In typical wall with Romex wiring, wire can be detected up to 51 mm deep Operating Temperature: -7° to 41°C Storage Temperature: -29° to 66°C Humidity: 5 - 90% RH (non-condensing) Water Resistance: Splash and water resistant, not waterproof Weight: 0.218kg without battery
