Key Features
🔍 3-in-1 Multi-Mode Detection
Quickly switch between Metal, Wood, and AC Live Wire modes. Locate hidden studs, rebar, pipes, and live electrical lines behind drywall, concrete, or plaster – all with one compact tool.
⚡ Live AC Wire Detection (90–250V)
Detects energized wires from 5–10 cm (approx. 2–4 inches) depth. Helps you avoid drilling into live cables – a must‑have safety feature for electricians and DIYers. Works with 110V and 220V systems.
📊 LCD Signal Strength + Audible Alarm
The LCD bar graph shows signal intensity in real time, while the buzzer beeps faster as you approach the target. No need to stare at the screen – the sound guides your hand.
✅ One‑Button Calibration (TEST Key)
Short‑press TEST to calibrate before scanning. This eliminates false signals and ensures accurate edge‑to‑center locating. Repeat from opposite direction for pinpoint precision.
⏻ Auto Power‑Off
Turns off automatically after 30 seconds of no use to save battery life. Long‑press power key for 3 seconds to manually power on/off.
🛠️ Ergonomic & Compact
Lightweight (144g / 5.1 oz) and slim (176×60×28 mm / 6.9×2.4×1.1 in). Easy to grip and slide smoothly over walls, ceilings, and floors.

🧹 Works on Most Surfaces
Paint, wallpaper (without metal foil), and even rough sprayed ceilings are fine. For very rough surfaces, slide a piece of cardboard between the scanner and the wall – performance stays excellent.
🔧 Solves Real‑World Problems
DIYer / Homeowner – Hang shelves or mount TVs without fear of hitting a live wire or water pipe.
Electrician – Quickly locate hidden AC lines before cutting into drywall.
Contractor / Remodeler – Find metal studs, rebar, or wooden joists behind concrete or tile.
🎯 Accurate Edge Detection
The TEST‑calibration routine lets you mark both edges of a hidden object. By scanning from opposite directions, you can pinpoint the exact center every time – no more guessing where the stud really is.
⚠️ Safety First
The live wire mode works on 90–250V AC (50–60Hz). The device alerts you before you drill. Always turn off power when working near wires, but even then, this scanner gives you an extra layer of confidence.
