What it does Detects metal objects and bolts inside walls and other materials. Locates live AC cables to help avoid electrical hazards. Identifies wooden elements such as handles and wooden trunks/studs. Combines bolt detection, metal stud finding, and wood-trunk/handle finding in one compact handheld tool. How it alerts you Acoustic alarm notifies you immediately when metal, wood or AC cables are detected. Analogue display provides a clear visual indication of detection strength to help pinpoint the exact location. Key benefits — why you need it Prevents accidental drilling or cutting into bolts and live cables, reducing risk and rework. Quickly locates metal studs and wooden studs/handles so you can place fasteners safely and accurately. Simple audible and analogue feedback speeds up inspections and installation work without complex setup. Compact, non-slip handheld housing makes the tool easy to handle and control in tight spaces. Important attributes Functions: bolt detection, metal stud finding, AC cable detection, wooden handle and wooden trunk/stud finding. Alerts: acoustic alarm plus analogue display for precise location feedback. Design: compact handheld housing with non-slip surface for secure grip and convenient use. Performance: reliable detection across metal, bolts, AC cables, and wood elements (handles/trunks/studs). Typical use scenarios 1. Mounting shelves or brackets: scan the wall first to find studs and avoid drilling into bolts or live AC cables. 2. Installing fixtures or running new wiring: locate studs and cables so you can route cables safely and secure fixtures to solid material. 3. Renovation or carpentry work: identify wooden trunks/studs and metal fasteners hidden behind walls to plan cuts, anchors, or removal without damage. Practical notes Use the analogue display together with the acoustic alarm for best accuracy: move the detector slowly over the area and mark the strongest response. The compact, non-slip housing is designed for one-handed operation and portability between jobs. This detector combines bolt sensor, metal stud finder and wooden trunk/handle finder functions into a single handheld tool to reduce guesswork and increase safety while working on walls and wooden structures.
