  1. Bosch, GMS 120

    Metal Setting

    The standard detection setting, the metal setting provides the best detection for magnetic (≤12cm) and non-magnetic (≤8cm) metals and can detect live wires up to a depth of 5cm on various wall types.

  2. Bosch, GMS 120

    Live Wire Setting

    While all settings detect live wires, the Live Wire setting provides best results when detecting live wires is the focus and can accurately detect them up to a depth of 5cm on various wall types.

  3. Bosch, GMS 120

    Drywall Setting

    Specialized for use with drywall, and can detect wooden and metal studs ≤ 3.8cm deep and live wires up to a depth of 5cm. This settings should only be used if the detection of wooden studs is needed.

Why does the signal change when I move along a live wire?

Twisting of leads of live wires causes variation in the strength of an electric field on the surface up to complete extinction. In case of a 3-phase live wire, the different phases of live leads cancel each other out.

Why do I have problems detecting a wooden stud in drywall?

Make sure to measure on homogenous drywall (e.g. no hidden holes or OSB walls). Choose the drywall setting before positioning the device on the wall, then wait until the LED ring turns on and start moving the device 3x over the area of interest.

Why does the device indicate live wires everywhere?

The device detects live wires by capturing the signal emitted by the live wire. If a wall has a high conductivity, this signal can be spread and over whole wall. Or, if a live wire runs parallel to rebar, all rebar might be shown as live wires.

What should I do if the device displays different results for the same measurement?

Follow the step-by-step guide when using the tool and make sure to do all the measurements the same way. In particular, move the tool 3x in each direction and keep the outer conditions constant.

Why does the device indicate metal objects on the whole wall?

The tool detects aluminium foil on underfloor heating systems and on thermal glass wool insulation as metal, and likewise detects brick reinforced w/steel fibre as metal due to the high iron content. It may show a yellow light w/red bricks or tiles.
