Review on 🔍 Bosch GMS120 Digital Multi-Scanner: Discover Wood, Metal, and Live Wiring Effortlessly! by Eric Young

SUMMARY: Don't buy. I tried two devices and couldn't reliably find wooden posts behind a tiled wall. I'm a handyman and sometimes need to find wooden studs behind tiled shower walls to install safety rails. Traditional nail finders work great on regular drywall surfaces. But when you have thicker materials and other materials like a cement baseplate or a HardiBacker with tiles on it, the search becomes more difficult. water pipes or electric cables. Checking by drilling a small pilot hole in the drywall is an easy and quick fix. Fixing a hole in a tile (even a small pilot hole) is a huge task, and it can be even bigger when I come across a water pipe or electrical wire! This device claims to be able to find wooden bolts, metal and electrical wires. I haven't checked the metal or electrical specs. All I had to do was find the wooden counters behind the tiled shower screen. Wooden shelves were found. But he not only found hairpins (slowly, but found), but also hairpins where there were none. If I had to rely on drilling holes in the tile to attach a handrail I would end up ruining a perfect shower screen! I used other methods such as finding a stud on the back of the wall and measuring to the same spot in the shower to ensure the stud finder was correct. This Bosch GMS120 Multiscanner didn't work for this use so I returned it for a refund. While my Franklin FS710PROProSensor 710+ sensors aren't perfect (available here at Revain), they're cheaper and more reliable! Not perfect, but definitely better than the Bosch GSM120.
