Rated 4 out of 5Â by trogo Quality Wall Scanner
I was frustrated buying cheap, throw-away stud finders that never seem to work when you need one, so I stepped up to the Bosch GMS120 Professional Wall Scanner. It comes with a nice flexible storage case with hand lanyard and belt loop. Using this wall scanner is not intuitive and requires reading the instructions thoroughly. There are multi-colored flashing lights, changing bar graphs, symbols and sounds that requires prior working knowledge to use properly. The instruction pamphlet would benefit from better graphics and illustrations.
The scanner has three modes; wood, metal or live electrical. In the wood mode it actually scans for all three, and will display the various signals and graphs on the display. It also identifies the center point of wood studs or metal objects. Selecting metal mode excludes wood and scans for only ferrous/non ferrous metals and âliveâ electrical wires. It is important to note that the scanner detects wires where current is flowing. The warning light may not flash for wires that have no current draw.
The Bosch GMS120 performed very well in all three modes during my testing and use. As recommended in the instructions, I used a thin piece of cardboard over the uneven ceiling texture, and it detected the joists perfectly. Now I donât have to drill and patch holes in the ceiling when looking for the joists. The scanner could be more user friendly with better graphics in the display, but itâs still a giant leap above the cheap stud finders.

Rated 4 out of 5Â by texastutt Very nice to use
This unit lets me know what is behind the wall for the most part. I gave it a 4 star as it gave me very error readings on a drywalled home where I could not figure out what was behind the existing wall. This could have more to do with what was behind the wall rather than the unit.
This unit will work with plaster but follow directions!

Rated 5 out of 5Â by Mrfxit Short learning curve
I have several "stud finders" that I have accumulated over time. None of them ever really exuded confidence to me that they were accurately detecting stud location. Forget confidence that I was actually driving a screw or nail close to the center of the stud. This new Bosch GMS120 eliminates the guesswork. In one situation I had the drywall open in a couple spots so was able to really see the accuracy of the center finder. It also quickly reports the presence of metal and electrical cables. I'm not an operators manual reader so I also liked the ease of use and quick learning curve of this device also.

Rated 1 out of 5Â by Thompson I got a bad unit...
My unit wouldn't pick up anything correctly, wood, metal or electrical. It gave out false readings constantly and led to much aggravation. After some online research I discovered that Bosch sent some faulty units to the states. I called Bosch and they confirmed the bad units being shipped over to the U.S. I attempted to return it to the Home Depot store where I bought it only I had lost the receipt and the store had pulled the stud finder from their shelves so they refused to take it back. Now I am stuck with an $80 paper weight. I will purchase a new one because I trust Bosch products but I will not buy it from Home Depot.

Rated 5 out of 5Â by Bill This is the best tool for finding studs, pipes and electrical wires.
I used the Bosh Digital Wall Scanner to locate the studs in my stairway. I located the studs without any problems, and the I installed an additional stair rail. It was a no brainier with this product. I'm not a carpenter just a do it yourself er.
