Detetor múltiplo digital Bosch GMS 120-27 cabo elétrico, metal, metal não ferroso, madeira

The Bosch GMS 120-27 multidetector is a handheld detection tool designed to locate metal objects, live electrical wiring and wooden studs behind walls, floors and ceilings. With a detection depth of up to 120 mm and measurement accuracy of 1 mm, it delivers clear visual and audible indications to help users avoid hidden hazards and position fastenings precisely. The device combines compact ergonomics with straightforward controls and a display optimized for rapid interpretation of scan results, making it suitable for renovation, installation and safety checks prior to drilling or cutting.

Advantages

The multidetector distinguishes between metal, live wiring and wood, providing both audible tones and visual indicators to reduce uncertainty during scanning. Its high detection depth of up to 120 mm and 1 mm measurement accuracy enable detection of deep or small objects with reliable positioning information. The tool’s compact handheld form factor and intuitive user interface permit efficient single-handed operation on vertical and horizontal surfaces. Robust construction and clear feedback support safer workflows and help prevent damage to utilities and structural elements.

Suitable for

• Pre-drilling and cutting checks in renovation and construction
• Locating studs and joists for mounting shelves, cabinets and fixtures
• Detecting hidden metal pipes, rebar or conduits in walls and floors
• Identifying live electrical cables before any invasive work
• Site inspections and safety verifications by installers and tradespeople

Key specifications

• Detection depth: up to 120 mm for metal, live wiring and wood
• Measurement accuracy: 1 mm
• Detection modes: metal, live wire, wood (multi-material detection)
• Output: visual display with clear icons and audible signal tones
• Power: battery-powered handheld unit for portable use
• Ergonomics: compact, single-handed operation with intuitive controls

How to use

Switch on the multidetector and select the appropriate detection mode for the material you expect to find. Hold the device flat against the surface and move it slowly across the area to be scanned, keeping consistent contact and orientation. Watch the display and listen for audible signals to identify the type and approximate position of hidden objects; use the 1 mm measurement resolution to refine placement for precise drilling or fastening. Repeat scans in perpendicular directions when necessary to confirm object orientation and depth up to 120 mm.

Recommendations

Before starting any drilling, sawing or routing, perform at least two scans at different angles and verify results visually where possible. Use the appropriate detection mode for the target material and replace batteries regularly to maintain accurate measurement performance. Keep the sensor surface clean and avoid rapid motions while scanning to reduce false readings. For installations involving complex or critical utilities, combine detector readings with professional utility plans or non-destructive testing for maximum safety.
