Will this tool find wood studs, wiring and pipes through 3/4" lathing /plaster walls?

Will this tool find wood studs, wiring and pipes through 3/4" lathing /plaster walls?
Asked by: RDK
It doesn't work with metal lath. It can work with wood lath, but it isn't easy. For finding studs, you have to make sure you are scanning along the lath, or the space between, in order to get a good reading. It does better at finding the nails in the lath, or pipes in the wall. It will usually find wiring as well. It takes practice to use it will plaster and lath walls. But it is better then others I have tried. I have a hose built in 1906, and I use it a lot here.

Customer Reviews

Digital Wall Scanner with Modes for Wood, Metal, and AC Wiring is rated 3.4 out of 5 by 106.
Rated 5 out of 5 by from It does it all as advertised. I bought this as a Christmas present for my son-in-law to replace a stud finder he lost in a flood. Perfect timing since I needed one to locate studs and miss copper pipes in a bathtub wall when I installed some grab bars. The centerline sensing of studs is a cool feature. You just have to read the instructions and remember to horizontally scan across the area a couple of times for the electronics to establish a density pattern. In my case, I needed to miss the studs by a minimum of 1" for those very large hollow wall fasteners used for grab bars. This instrument will detect water pipes and electrical conduit, BX and Greenfield. It will not sense Romex or similar type of wiring that is NOT live. The circuit has to be HOT and the instructions are very clear on that. A previous reviewer was complaining about that and apparently didnt read the instructions. Given a choice of brands, I alway choose Bosch when possible because of total value...workmanship, quality, durability.

Rated 5 out of 5 by from Great precision I just bought this stud finder today and it is the very first stud finder to actually find the rafters in my ceiling. I have tried quite a few others and always had to hunt for the stud. This one did exactly what it said. Good job Bosch.

Rated 4 out of 5 by from 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 “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.

Rated 4 out of 5 by from Located rebar 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.

Rated 4 out of 5 by from Does what it says except on carpet This is a very good and solid wall scanner, it does what it says and is very accurate in finding studs behind drywall. It has a bunch of nice features and I prefer to use it over my cheaper Zircon stud finder. It has a nice opening so that you can easily mark the drilling location. A simple but very convenient feature. The display, lights, and tones are all very useful especially when working in tight locations or on ladders. I wanted to use this to locate floor joists under berber carpet in order to drive some screws to fix flloor squeeks. The manual says it can do such job. I was disappointed with its inability to detect those joists. It kept beeping like crazy and gave irregular results no matter which direction I ran. My Zircon stud finder also struggled and couldn't get this job done so I'm sure this has a lot to do with the type of carpet and thick undercarpet layer. I also tested the feature to detect wiring in the wall, and this works well as described. I did not test the feature of detecting rebar in concrete walls. I cannot give it 5 stars since I was expecting a better result for undercarpet floor joist detection.
