Rated 3.0 out of 5.0 by jweisbart Works good for wood, not so much for electrical.
I had just remodeled my bathroom so I knew where all the studs and electrical was located. It worked great to find the studs. The display showed where the center was clearly. It even has a hole to mark on the wall.
But I tried the electrical setting and it found the live wires sometimes and sometimes not. I even tried it over exposed wires and it didn't sound off.
Overall, it worked great for wood, not so great for electrical. I didn't have an occasion to try it on steel setting.

This item arrived in a plastic bag with a hole in it. The box itself didn't have any protective packaging around it and it looked like it had been opened once...possibly already returned? It was a Christmas gift to my husband so I wrapped it but was worried if it would work and, of course, it didn't. We returned it to the store and did not try our luck with purchasing another one online through your store.

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 “live” 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 don’t 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 it’s still a giant leap above the cheap stud finders.

Decided to go with a better stud finder and was not disappointed. Finds studs easily and I like the centering function.

Rated 2.0 out of 5.0 by Keen High hope deflated.
Had high hopes for this detector as Bosch makes great products. I liked the size and layout of the buttons and the backlight is great for low light areas. Thats about as far as the pro's went. The detector reads a green light as a you scan and flashes red when an object nears - confuses me, imo. it should be the other way around. When you approach an object the display "bar segments" increase until the center is found. Sounds great but I had so many false readings i didn't know what was behind the simplle 1/2" sheet rocked wall. I compared the same wall w/ a B&D dtector and had much better results. Bottom line save your $.

Rated 1.0 out of 5.0 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 1.0 out of 5.0 by Flyer Quality not what I expected
It was time to treat myself to an upgraded tool to replace my ten year-old stud finder. I bought the Bosch with the thought it was a high-end tool. The device isn't intuitive and requires multiple references to the manual. Most notably, the "Live" wire feature didn't pick up any live wires at all. I tested it against a power cord for a radio and then it worked, but wouldn't pick up electrical in known locations. The first stud it identified now has a molly bolt in its place. This tool is going back.

This scanner is so easy to read . It can find studs in walls that other scanners cant find. It is lightweight and so easy to get into places that you cant do others
