Bosch wall scanners and detectors find rebar, metal pipes, wooden studs, plastic pipes and live wires inside walls, floors and ceilings before you drill or cut. They prevent damage, costly repairs and electric shock on renovation and installation jobs.
How to choose a Bosch wall scanner
- Detection depth: 100mm to 120mm covers most walls. 150mm to 200mm models scan deeper into slabs and thick concrete.
- Materials: GMS detectors find metal, wood and live wires. D-tect radar scanners also detect plastic pipes and show objects on a display.
- Screen and data: D-tect 200 C shows a scan image and can save results for reports.
