High-accuracy detection: Updated internal sensor locates the bolt centre precisely and consistently. Rivet edges are displayed on the screen so you can identify fastener locations quickly and position drills or anchors with confidence. 4-in-1 multifunction scanner: Four detection modes cover common site needs: Bolt scan Depth scan Metal scan — up to 60 mm AC scan — up to 51 mm These modes let professionals, homeowners and DIYers find bolts, metal, studs and live wiring fast and reliably. Cable protection and safety alert: Built-in cable alarm detection reaches a depth of up to 60 mm and warns you when AC cables are present. The alarm operates during beam scanning, depth scanning or metal scan mode to reduce the risk of cutting or drilling into live cables. Clear visual and audio guidance: Large LCD display shows detected objects and rivet edges. An acoustic alarm provides directional and intensity cues — beeps change with proximity to the target so you can pinpoint the exact location quickly. Wide surface and application compatibility: Detects metal, wooden beams and live cables hidden in walls, ceilings and floors. Works on common surfaces including concrete, tiles and wooden boards. Practical use scenarios: Mounting a wall-mounted TV or shelving: Locate studs, bolts and rivets behind drywall or tile to choose secure fixing points and avoid hidden cables. Running or repairing electrical wiring: Use AC scan and cable alarm to detect live cables before cutting or chasing walls. Renovation and tiling work: Verify beam and metal locations in concrete or tiled surfaces to avoid structural or electrical damage during drilling.
