GPR can detect metallic and non-metallic objects in the ground. In many cases it is the only non-intrusive method to detect and designate the location of e.g. non-metallic utilities such as plastic and concrete, where standard locating technology cannot provide the complete picture. The SWH system breaks many barriers in terms of ground penetrating radar systems on the market today. Very little experience is needed to operate the system. With a simple user interface and a few commands it is ready for data collection at walking speed.
