The Hilti PS 30 and PS 35 provide an easy and reliable means of locating metal objects such as steel reinforcing bars or water pipes in concrete and masonry. They make it possible to drill through these materials safely and without risk of structural damage. Featuring a large, clearly laid-out LCD display, generously sized gripping areas and audible as well as visual indication of the position of metal objects, these tools are exceptionally user-friendly. Both differentiate between ferrous and non-ferrous metals. Single button operation makes the PS 30 impressively easy to use. The PS 35 is also capable of detecting live electric cables.
