Description
Features:
Clear and simple: the intuitive wall scanner that makes the invisible visible
Gives you confidence by detecting metal, live wires, and wooden studs behind the wall
Easy to use with simple mode selection and marking hole
Built for operation on tough job sites thanks to shock-absorbing rubber casing and IP54
When you’re drilling into a wall, you want to get the job done, confident that you won’t hit an obstruction. Our GMS 120-27 Professional wall scanner allows uncomplicated and intuitive detection of objects. Detection results appear via signal indication on the display and the colour-coded marking hole. The easy-to-use detector offers simple mode selection, and you can mark exactly through the marking hole where objects have been detected. The robust GMS 120-27 was developed for tough job sites with IP54 dust and splash water protection, plus a shock-absorbing rubber casing.
Our GMS 120-27 Professional wall scanner helps you detect and locate metals, live wires, and wooden studs in dry walls. Locating objects in walls before drilling provides increased safety on the job, especially for craftspeople doing renovation work when fitting cabinets, kitchen counters, washbasins, boilers, and heating systems, or installing A/C and sprinkler systems.
Not only does this scanner identify the center of the detected object, it also indicates its material characteristics such as whether the object is magnetic or non-magnetic metal, a live wire, or non-metallic.
