Bosch Truvo Digital Detector - 2nd Generation

Before you drill into a wall to hang a shelf, mirror or TV bracket, the Bosch Truvo helps you check for metal pipes and live cables. There's one button: switch it on, slide it across the wall and follow the traffic-light LEDs.

It calibrates itself, so there are no settings to learn. Green means clear, red means something is there, and a warning tone backs up the lights.

Why it's worth a look

• Detects ferrous and non-ferrous metal, so it picks up copper pipes as well as steel
• Finds live cables up to 50 mm deep
• Small and light at 0.15 kg, so it lives happily in a kitchen drawer
• Batteries are included, so it's ready to use straight away

Good to know

A detector is an aid, not a guarantee. Depth depends on the wall material and the size of the object, so always drill with care, and turn off the power at the consumer unit if in doubt.
