BOSCH GMS120-27 Professional Wall Scanner, Multi-Function Stud Finder, and Live Wire Detector for Electricians, Plumbers & Contractors, Wall Detector

** Bosch GMS 120 Stud Finder** The Bosch GMS 120 Stud Finder presents a mixed bag of experiences among its users. While some customers praise its overall functionality and reliability in detecting various objects, including metal and live wiring, others express frustration with its stud-finding capabilities. Many users who expected the GMS 120 to fulfill its primary role of locating wooden studs found it underwhelming. Critics complain that the tool frequently misidentifies materials behind walls, providing false readings and causing confusion for users who are attempting to identify the location of studs accurately. Several reviews indicate that while the GMS 120 performs well in identifying metal and electrical wiring, it fails at its core function of detecting wooden studs with precision. Users expressed that the tool's indicator system—commonly lit in red for positive readings—can be misleading. Many felt that the distinction between different types of objects was unclear and resulted in a lack of confidence when trying to drill or fasten through walls. However, it's worth noting that some professionals found the device useful for specific trades, like plumbing or electrical work, where knowledge of hidden pipes or wires is more critical than the exact location of studs. Despite its capabilities in those areas, homeowners and DIY enthusiasts looking to complete basic carpentry tasks might be better served by alternative options in the market that focus on stud detection with higher accuracy. In summary, the Bosch GMS 120 may appeal to professionals needing to avoid hazards behind walls, but it lacks the reliability and user-friendly design necessary for straightforward stud finding. Its premium price point coupled with disappointing performance in finding wooden studs leaves much to be desired for those seeking essential home improvement tools. **
