MultiScanner i700 OneStep quickly and easily locates the edges and centre of wood and metal studs and joists behind walls, floors, and ceilings. It also locates metal as well as live AC electrical wiring. The ultra-bright display screen, SpotLite Pointing System, and audio tone all indicate the location of the target. The signal strength indicator helps to distinguish between shallow and deep targets. Sensing depth and accuracy can vary due to moisture, content of materials, wall texture, and paint.
