Product Overview
The Bosch Truvo is a compact digital detector designed for home use to locate metal objects and live electrical wires behind walls. It provides a simple, intuitive interface to help users safely drill or mount items without damaging hidden infrastructure.
Safety Instructions
To ensure accurate detection and personal safety, please observe the following guidelines:
- Grounding: Ensure you are properly grounded when using the device. Avoid wearing insulating gloves or footwear that may interfere with the detection of live wires.
- Interference: Keep your free hand flat against the wall near the device to help calibrate and improve detection accuracy.
- Environment: Do not wear jewelry or metal accessories that could interfere with the sensor readings.
Operation and Usage
The Truvo uses a traffic light system to indicate the presence of objects:


- Green: No object detected. It is safe to proceed.
- Yellow: An object is nearby. Proceed with caution.
- Red: An object has been detected. Do not drill or drive screws in this area.
For optimal performance, move the device slowly across the surface. When searching for live wires, it is recommended to have a device plugged into the circuit and turned on to create a stronger electrical field for the sensor to detect. Always scan the area multiple times in different directions to confirm the exact location of the hidden object.
Maintenance and Troubleshooting
Keep the device clean and dry. If the device fails to detect objects, ensure the sensor area is clean and that you are maintaining proper contact with the wall. If the device behaves erratically, ensure you are not wearing gloves and that your free hand is placed on the wall to provide a reference point for the sensor.
Disposal
Dispose of the device and its packaging in accordance with local environmental regulations for electronic waste. Do not discard with regular household trash.
