Product Information

Full details

The Bosch GMS 120-27 Professional wall scanner is designed for tradespeople performing renovations, installations, and interior fittings who need to confidently drill into walls without hitting hidden obstructions. Its key benefit is fast, accurate detection of metals (magnetic and non-magnetic), live wires, and wooden studs, offering peace of mind. A potential caveat is its limited detection depth for wood at 30mm, requiring users to be mindful of wall material thickness.

FAQs

What is the maximum detection depth for wood?

The maximum detection depth for wooden substructures is 30mm.

Can this scanner detect metal pipes in concrete walls?

The GMS 120-27 is primarily designed for drywalls. While it may detect metal in other materials, its accuracy and depth limitations are specified for drywalls. For concrete, specialized scanners may be required.

What types of batteries can be used?

The scanner supports 2 x 1.5v LR6 AA, 2 x 1.2v HR6 AA, or 1 x BA3.7v 1ah Li-Ion battery.

Does the product come with a carrying case?

No, the Bosch GMS 120-27 Professional does not include a hard carrying case. It comes with a pouch for basic protection and portability.

How do I ensure accurate readings?

Always calibrate the device by placing it flat on the wall and pressing the center button before scanning. Move the scanner slowly and steadily across the surface, and ensure you are using the correct mode for the material you are trying to locate.

What does IP54 protection mean?

IP54 protection means the device is protected against dust ingress to a harmful level and protected against water splashes from any direction.

Can it detect non-live wires?

The scanner is designed to detect live wires. It can detect metal, which may include non-live wiring, but its primary function for wires is detecting active electrical currents.

Troubleshooting

Device not powering on

Ensure batteries are inserted correctly and are charged or new. Check battery contacts for dirt or corrosion.

Inaccurate readings

Recalibrate the device by holding it flat against the wall and pressing the center button. Ensure you are using the correct mode for the material being detected. Avoid scanning near large metal objects or power cables not related to the detection area.

No detection signal

Verify that the object is within the scanner's detection depth (e.g., wood up to 30mm, live wire up to 50mm). Ensure the object is the type the scanner is designed to detect. Check battery levels.

Display is unreadable

Ensure the display is clean and free from dust or moisture. Check battery levels, as low power can sometimes affect display brightness.
