2.0 out of 5 stars Not accurate June 16 2013
By azrim1

Purchased this thinking it'd be better than the cheaper Zircon but its below average in finding studs in my opinion. As I own other Bosch tools and am quite happy with them, this one I would pass on. I missed several times in the garage while installing a slat wall. Now I have a few screw holes to patch up no thanks to this gadget. I would not recommend this product if accuracy is your prime concern.

I opted for the less expensive scanner, and so far it has performed very well. I was reluctant to spend a lot more and not get good performance.

4.0 out of 5 stars Pretty good Feb. 8 2014
By Breeze
At first I thought, what a waste of money, but them I read the instructions again, and went threw the steps sssssllooowwwlyyyy, what a dif, please read and follow the instructions, Now I use thise all the time. some times still its hard to find studs, so I will go back to my Zircon, but that does not make uch of a differance, so I use a trusty magnet, when I find a jip screw, thats my stud, all in all this unit works very good , like I say read the manual, and you must be patiant pass slow with the stud finder , and usualy its very acurate .

4.0 out of 5 stars Bosch GMS120 Digital Multi-Scanner Dec 2 2013
By Bob
Verified Purchase
The Bosch GMS120 Digital Multi-Scanner arrived prior to the estimated time of delivery. It was packed well. It comes complete with good quality batteries. The product functions well overall. Though it is less accurate scanning through masonry compared to wood overall. I have not yet found the tool to be overly clear or accurate identifying power cable or copper plumbing as expected; this could be my lack of familiarity rather than the tool itself as I am giving myself time to learn the ins and outs of the tool, Other than that element, the tool works great for zeroing in on the edges of floor joist and studs so you know where to set your center line presuming the joist or studs are not curved. Accurate for me other than the metal element which I was expecting to function as straight forward as the wood element. I expect if I want the Buckingham Palace version I will need to spend the big bucks on the far more advanced Bosch D-Tect150 D-Tect Wallscanner version. In conclusion, for closer to 10% of the price this works quite well for most of my needs.
