is the battery included?

Asked by: Anonymous
Yes, a 9V battery is included. The answer from Bosch on your question is actually wrong.

what types of wire will it detect.

Will it detect live and non-live (disconnected) electrical wire?
Asked by: Bahr
In my experience, like many other reveiwers, it does not find any wires. It should however find live wires per their instructions

Can it detect water leaks Can it detect over cement

Asked by: Alexis
Thanks for your question. The GMS120 is designed for detection of wood studs, metal objects (rebar, studs and steel/cooper pipes) or live wiring. We do not make a product that will detect water leaks.

Digital Wall Scanner with Modes for Wood, Metal, and AC Wiring is rated 3.4 out of 5 by 66.
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 1 out of 5 by from I bought this to help with professional and personal projects. When we do handrails in the houses... I bought this to help with professional and personal projects. When we do handrails in the houses we build sometimes the blocking installed during framing isn't exactly where it's supposed to be, so having a good wall scanner is important, especially since just finding the studs isn't sufficient if we want the handrail brackets to be properly spaced. So I got the GMS120 and started trying it on some remodel work, where I had a 5/8" drywalled wall that was open on one side and had pipes and live wires in the cavity. I compared the GMS120 to my Zircon that cost waaaay less. Zircon: Found every stud, and alerted at the wire. No false positives. Some of that annoying erroring out, but otherwise good. Bosch: Found lots of non-existent studs. Sometimes alerted at the correct studs, but not always. Gave a lot of alerts about metal where there was no metal, flipping between ferrous and non-ferrous. DID NOT ALERT AT LIVE WIRES. Gave alerts for wires nowhere in the vicinity of live wires. What's more, the Bosch GMS120 is IMPOSSIBLE to view if it is below eye level at all. The LCD display has been oriented or polarized in a way that means you have to be 90 degrees or less below perpendicular to the plane of the LCD. This means most of the time you need to use the GMS120 upside down or sideways, unless you want to always be crouching. This is made worse by the all the false alerts the GMS 120 gives, so you really need to watch the screen to see if it's alerting to metal or a non-existent wire or alerting to a stud. The manual is atrocious. It is entirely unclear how to calibrate the unit once it's placed on the wall (press the wood/metal/elec mode button), and there's no *clear* description of how to use the scanner. There's a lot of flipping back and forth in the manual between general use instructions and specific mode usage. The interjection of part/button numbers in the text is odd and distracting. I am returning this.

Rated 4 out of 5 by from Good features and good accuracy I like the feature of moving the unit back and forth to home in on an exact location. Haven't tested to any great depth, but the accuracy seems good.

Rated 3 out of 5 by from Meh ! I bought this thinking it would help me detect live wire but found it a bit erratic & in consistent I would scan the same area twice with a different reading. Sorry bosch when it comes to wires I think its a dud

Rated 1 out of 5 by from unreliable i bought this product a year ago used once then put in toolbox now doesnt want to read anything but just beeps as if theres live wires.

I needed to find electrical wires, and read the reviews and thought, no way is this not going to work, people just don't know how to use it. But to my dismay, they were correct about the electrical identification issues. It does function well as a stud and metal locator, but not electric. I bought 2 of these, and I made several passes, but neither would find any live wires. I even exposed the sheet rock above the live wires, making sure the switch was on, but even scanning directly over the wires, it did not show anything
