did its job
the hole is a clear indication of designers making a prank to worker's pensile :) | I am interested in using this on my concrete walls. Can I use this on concrete walls? | I got this Bosch wall scanner and it’s absolutely amazing. Makes for hanging pictures a breeze. Love that it shows me where the wires and studs are. My favorite is I can use the hole and make a mark so I don’t loose my spot. Comes with a case for easy storage. Works so good. Highly highly recommend. | This thing is so nice and fancy. After using a cheap stud finders my whole life this is a game changer. Not heavy and easy to use. Would recommend to all my diy girlies. This thing finds the studs and wires so easily and accurately. | Lightweight, durable, and fairly easy to use locating studs, and metal, but more troublesome locating electrical. My experience locating electrical wires for me was mixed success, I renovated a 63 year old lake cabin and know where electrical Romex was run in my 2x4 construction home. As the manual states, it is easier to find energized wiring while my success rate indicated it still was a hit or miss proposition thru half inch drywall. Most other uses worked as advertised, like finding metal or wood studs was just as easy using more inexpensive studfinders. The center ring was a great added feature for marking the wall but a little short sighted for professional carpenters using the square pencils because they don’t fit in the opening.
My biggest beef with preparing to use the GMS 120-27 was the manual, it is poorly laid out for device familiarity and Bosch (for such a high quality company; based on previous purchases) should seek out and hire better (read much better) technical report writers, my experience indicates if the user finds it difficult to find information in the manual, user satisfaction suffers overall. For example, Page 1 and 2 provide a pictograph of the device but it is 10 pages later you will find the Functional Description of each itemized point in the Pictograph, this results in many page flips for the user. Bosch should also remove optional accessories from the main pictograph to avoid confusion and label as such on a separate page to clearly indicate “Available for purchase separately”.
Overall a great device to have and use but widen the hole for carpenter pencils and refine the electrical function. | I used the scanner for the first time to locate the studs for an exterior ledger board to secure a lean too. The tool was able to detect the studs at a random layout. The scanner read through vinyl siding and 5/8" insulation sheathing. Pros: audio sound and shows exact center. Cons: took me awhile to learn the functions being a first time user of this product. | This scanner is a must have for just about any drywall project. Right out of the box I like that it has a clip on the pouch to clip to your work belt.The scanner itself is easy to hold and everything is easy to read. The big seller for the scanner is it can detect wood,studs,metals and live wire and everything has its own detection image making it easy to use. | I highly recommend this tool . It works extremely well and very fast . It has a lot of extra bells and whistles on it to efficiently find the areas in the walls you need to be able to locate. Makes your job a lot easier and more effective. | This product is really handy to detect studs/wood, metal/copper and electric wiring. I find it very easy to use, it's got a good feel to it. Perfect for carpenters, renovators or just your ordinary individual doing small jobs around the house... I totally recommend it! |
