When drilling in the wall, you want to get the job done and be sure that you won't hit an obstacle. This GMS 120-27 Professional locating tool allows you to locate objects easily and intuitively. The locating results are shown via a signal indicator on the display and the colour-coded marker hole. The user-friendly locator offers simple mode selection and the marker hole allows you to mark exactly where objects have been located. The robust GMS 120-27 was developed for harsh construction sites and is equipped with dust and splash water protection to IP54 and a shock-absorbing rubber housing. The GMS 120-27 Professional locating device helps to locate and localise metals, power lines and wooden beams in drywalls. Locating objects in walls before drilling makes for safer work, especially during renovation work when fitting cupboards, fitted kitchens, sinks, boilers and heating systems or installing air conditioning and sprinkler systems. This locator not only determines the centre of the located object, but also indicates its material properties such as magnetic or non-magnetic metal, a live wire or non-metallic material.
