The UtilityScan ground-penetrating radar (GPR) system from Geophysical Survey Systems Inc. (GSSI) locates metallic and nonmetallic targets, including plastics, cementitious materials and fiberglass. It can also detect trench lines if a pipe is obscured.“Ground-penetrating radar can detect pipes without tracer wire or those that cannot be traced with electromagnetic locators,” says Peter Masters, applications specialist for GSSI. “Having the ability to quickly and effectively locate pipe enables users to finish jobs faster and complete more jobs during the day.”GSSI recommends using GPR in conjunction with other locating technologies, such as electromagnetic locators, metal detectors, sondes and even leak locating equipment
