1. PRECISION CONSISTENCY: Our upgraded metal detector utilizes an internal sensor to identify spatial density changes behind walls, enabling accurate bolt center detection. It also displays stud edges for easy location verification, simplifying and enhancing your DIY projects. 2. 5IN1 DETECTION: Featuring an advanced 5in1 mode, this wall scanner adapts to various detection requirements. The bolt scan mode detects wood at depths of 1/2' (12.7mm) and 11/2' (38mm), while the metal scan mode identifies metals up to 2.36' (60mm) deep. The AC scan mode reaches depths of 2' (51mm), saving time and effort for professionals, homeowners, and DIY enthusiasts. 3. CABLE PROTECTION ALERT: The cable alarm function warns users of live AC cables up to 2.36' (60mm) deep when operating in stud scan, deep scan, or metal scan modes. This feature prevents potential cable damage and enhances safety during use. 4. CLEAR DISPLAY AUDIO ALARM: Equipped with a large LCD screen and audible alerts, our cable detector ensures easy reading and precise target positioning. The LCD displays directional and intensity cues, while beeps guide you closer to the target, significantly speeding up detection. 5. VERSATILE APPLICATIONS: Designed to locate hidden metals, wooden beams, and live wires in walls, ceilings, and floors (including concrete, tiles, and wooden panels), our wall scanner suits diverse scenarios, delivering reliable performance for both professional and projects.
