I bought this scanner about 2 months ago to help with assisting in finding live wires and copper pipes in the walls where I work. I'm a maintenancce technician and I do a lot of sheetrock repair and replacement. in the past I had to use a cheap little stanley wall scnanner that couldn't find a wall stud to save its life. I stumbled upon the bosch gms120 by accident online and read what it could do and decided to spend the extra money to try it out. I bought it online and when it arrived I put it to use asap. The stud finder is dead on accurate and the ability to find the center of the stud helps tremendously when cutting drywall and installing screws into the wall. The metal detection features are also very acurate in finding copper pipe and or rebar and the fact that it can distinguish between ferrous and non ferrous metals helps out a lot. The only issue I have with the scanner is the live wire detection. There has to be 120v+ power flowing through the wire to detect it and sometimes the scanner doesn't find the live wires. I've had the scanner right over live wires with 120v running through them and the scanner picked up a weak signal. Other than that this scanner works way better than I could ever imagine or expect. I highly recommened this scanner to any homeowner or professional out there. The cost is a little bit much but well worth is if you use it often.

I have had the opportunity to use this device twice. Each time I knew I was looking for rafters above a ceiling that was set down 1/2-inch from the rafters with metal supports. Neither the rafters nor the metal bars were detected. I did use the "wood" and "metal" detection settings. I have 20-plus other Bosch products which I use (mostly) without issue or concerns.

Located rebar

By RichardL

from Ontario, Canada

Comments about Bosch Digital Wall Scanner (GMS 120):

I received this tool as a Christmas gift to replace me dead stud finder. My first use of the tool was to see if it would detect rebar in a six inch thick concrete floor. I had a fairly good idea where the 12" X 12" grid was but this tool allowed me to install 4" anchors with increased confidence. I was installing an automotive hoist...5 anchors per column. I did not hit one rebar (rebar was installed on 3" pedestals so it should have been 3" deep...my holes were 5"). I am looking forward to testing the other features of this tool but considering that I only expected it to be used for finding studs the tool has already exceeded my expectations. My rating may seem low considering this note but since I have yet to try any other functions of this tool I think 4 is pretty fair.

Very nice to use

By texastutt

Comments about Bosch Digital Wall Scanner (GMS 120):

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!

Short learning curve

By Mrfxit

from Undisclosed

Comments about Bosch Digital Wall Scanner (GMS 120):

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.

Outstanding features

By REGENCY

Comments about Bosch Digital Wall Scanner (GMS 120):

Bought this for several reaons: 4.5 inch depth reading; auto center; locates rebars in concrete. Beats the top of the line stud finders I already have. Easy to use, even for my wife.

Looks good, fails to deliver

By missmagic

from UK

Comments about Bosch Digital Wall Scanner (GMS 120):

I trust the Bosch name, and in part that was why I was prepared to pay so much for a cable detector. A decision I now regret. It may just be this unit, but the results are so erratic on cable detection to be totally useless, and potentially dangerous.

Best Uses

    Comments about Bosch Digital Wall Scanner (GMS 120):

    Product is easy to figure out. I read the directions; very confusing. SO I tried it for a while, then read the directions. They make much more sense. They need to be rewritten, so don't start with the directions. Just play with it. It does a good job of detecting and is easy to use. Once you want to do more technical detecting (live wires and such) then check the directions as there is handy info about each mode and what it does, in the manual.

                    I received it in the mail and put it to work right away. It did everything the manufacturer promised. Easy to use and easy to understand. The directions were simple enough a child could use it. Very happy with the product. I like the backlight and the fact it will tell you where wires are behind the wall.
