NOYAFA NF-518 Wall Detector, Multifunctional Metal Wood AC Live Wire Scanner, 120mm Depth, Voice Broadcast

The NOYAFA NF-518 Multifunctional Wall Detector is a professional-grade wall scanning tool designed for home improvement, electrical wiring, and DIY drilling projects. The NOYAFA NF-518 supports three detection modes – metal, wood stud, and live AC wire – with maximum detection depths of 120mm for magnetic metal, 100mm for non‑magnetic metal, 38mm for wood studs, and 50mm for live AC wires. This NOYAFA NF-518 wall detector features a 2.4‑inch HD color screen that shows target type, signal strength, and depth in real time, plus live voice broadcast that announces detection results so you can keep your eyes on the wall. With center positioning indicator and signal strength bar, the NOYAFA NF-518 helps you locate the exact center of hidden objects, avoiding costly mistakes and making it an ideal choice for electricians, contractors, and DIY enthusiasts. Detection Modes Metal Detection Mode – Distinguishes magnetic metal (rebar, iron pipe, steel stud) from non‑magnetic metal (copper pipe, aluminum tube). The screen displays metal type icon, signal strength, and depth information. When signal peaks, the center mark lights up – indicating the metal is directly below the sensing area. Unaffected by wall material characteristics. Wood Stud Detection Mode – Scans for wood studs, joists, light steel keels, and cavities behind plasterboard, plywood, coated wood, and drywall. Offers both auto‑calibration and manual calibration. When a material change (stud or void) is detected, the screen shows "stud" and signal strength. The center mark confirms precise target location. Live AC Wire Detection Mode – Designed exclusively for locating live AC wires (up to 50mm depth). When a live wire is detected, the screen shows a live icon and signal strength, and voice broadcasts "AC". For best accuracy, move the instrument slowly back and forth multiple times to pinpoint the live wire location – reducing the risk of electric shock when drilling. System & Sensitivity Settings Independently adjust sensitivity for metal, wood, and AC modes to suit different wall materials and environmental conditions. Metal detection calibration: if false alarms occur due to temperature or humidity changes, run calibration through the system menu (ensure no metal or strong magnetic field nearby before calibrating).

• ‌3-in-1 detection: metal (magnetic up to 120mm, non-magnetic 100mm), wood (stud/joist/gypsum board 38mm), live AC wire (50mm); avoids drilling into hidden hazards.
• Real-time center positioning & signal strength bar: pinpoints target center with illuminated center mark; signal bar shows proximity; reduces guesswork and errors;;
• Live voice broadcast + HD color screen: 2.4-inch display shows metal type, depth, signal strength; voice alerts keep hands free during operation;;
• Auto & manual calibration: auto-calibration for quick start; manual mode for dark or uneven surfaces; ensures accurate readings on various walls;;
• Adjustable sensitivity for 3 modes: customize sensitivity for metal/wood/AC detection independently; adapts to different wall materials and environments;;
• Type-C rechargeable with auto-off: 390mAh lithium battery; 5-minute auto power-off saves energy; no frequent battery changes needed;;
