Bosch GMS120 Digital Wall Scanner is rated 2.7 out of 5 by 28.
Rated 1 out of 5 by from Don't waste your money This detector will definitely fail after a little use. Do not waste your money. It will end up detecting cables in mid air which renders it useless at detecting anything.

Rated 3 out of 5 by from Bosch Wall Scanner Bought for specific task in locating studs and cables for wall mounting of TV. Was pretty accurate but required multiple sweeps to discount false readings. Overall happy with the tool and would recommend

Rated 1 out of 5 by from Pointless waste of money Random live wire readings all over the place where there’s no wires (in wall and ceiling plaster and brick - all old and dry). Doesn’t detect stud work with any consistency. Detects metal where there is none. A very disappointing and expensive object, particularly as it’s a Bosch Pro range.

Rated 5 out of 5 by from Good Wasn't too sure after the mixed reviews, glad I took a punt seems to be pretty accurate. And easy to use

Rated 5 out of 5 by from Good wall scanner This has been great so far, on the two jobs I’ve used it on. It is accurate and user friendly, a must for any toolkit

Rated 1 out of 5 by from Dangerous The first one didn't work, so I sent it back under warranty. The replacement thinks that timber studs are electricity and is very inconsistent with detection. No point in having a detector that you don't trust. Very disappointing for the cost and very dangerous if it gives you wrong information.

Rated 2 out of 5 by from Poor show from bosch Nowhere near the quality expected from Bosch, First use straight through electric wire (what are the chances !!!!) can not detect electric cable unless 5mm away, remaining holes had to be drilled using the metal setting. I hope it just a faulty unit so will exchange and try again

Rated 1 out of 5 by from Money back please. Bought this unit purely for finding studding in a Georgian property. Totally ineffective, giving a myriad of false readings and unable to detect studwork on newly built walls with 12mm plaster board and only 2mm of plaster skim. I have spent 5 minutes trying to make it detect a stud which I knew the position of ! Absolutely useless, and unexpected from Bosch, I will be seeking a full refund.
